Full textAbstract:
Distribution and abundance of the carangid larvae collected during ten survey cruises in the southeastern Brazilian Bight were analyzed. Trachurus lathami was the most abundant species in the surveyed area with 58.54 % of total carangids taken, followed by Chloroscombrus chrysurus with 15.22 % and Decapteruspunctatus with 12.17 %. Larvae of T lathami and D. punctatus were found all over the continental shelf while the distribution of C. chrysurus larvae was limited to the coastal region. Most of the species occurred all year-around but remarkably during spring and summer. This intensive spawning period of most carangid species seems to be related to the seasonal variation of the hydrographie structure of the southeastern coast of Brazil.

Full textAbstract:
Prosorhynchoides lamprelli n. sp. (Digenea: Bucephalidae) is described from the intestine of the brassy trevally, Caranx papuensis (Carangidae) from off Lizard Island, Great Barrier Reef, Australia. The new species is differentiated from other species of Prosorhynchoides Dollfus, 1929 by the shape and distribution of its vitelline follicles, the shape and extent of its uterus and the configuration of its digestive system. This is the first bucephalid to be described from Caranx papuensis; we have not encountered this species from other carangids or from over 1,500 individuals of other teleosts species we have found to be infected with bucephalids from the Great Barrier Reef.

Full textAbstract:
Carbon and nitrogen stable isotopes were used to describe an estuarine mangrove food web in New Caledonia, SW Pacific. Isotopic values were measured for all components of the ecosystem, from various organic matter (OM) sources to predators. Primary producers showed δ13C values from −32.29‰ (Bruguiera gymnorhiza) to −24.67‰ (mouth particulate organic matter), whereas δ15N values ranged from 1.48‰ (Avicennia marina) to 10.17‰ (Eichomia crassipes). Two potential organic matter sources, i.e. the mangrove species and E. crassipes, appeared not to be directly used by consumers although were indirectly entering the food web through particulate and sedimentary organic matter pools (POM and SOM). Overall, invertebrates showed C-depleted and N-depleted values compared with fish, highlighting their lower trophic level. The highest trophic levels in this estuarine mangrove were represented by carangids (δ15N of 11.24‰ for Caranx sp. and 10.81‰ for Carangoides fulvoguttatus) and gerrids (δ15N of 10.42‰ for Gerres filamentosus). Two main pathways of organic matter were identified from sources of OM to end-members, i.e. from estuarine POM and SOM toward gerrids and from marine POM towards carangids. The food chain comprised three or four trophic levels, depending on the pathway of organic matter. The position of some consumer species within the reconstructed food web might imply that an important source of organic matter was probably missing, i.e. microphytobenthos. Despite an obvious connection, the role of river inputs as potential drivers of mangrove food web dynamics appeared important only during the wet season.

The present study was the first attempt to investigate the public health importance of infestation of Ostracoda in some marine food fishes in southeast region of Tamil Nadu India during June 2019 to May 2020 by the method of Becker’s measuring utility by a single-response sequential method. Total 540 fishermen belonging to 5 villages from Ramand District were interviewed to understand the public health issues related the infestation of Ostracoda V. tsujii in ten major marine food fishes i.e. Parupeneus indicus, Lutjanus fulviflamma, Priacanthus hamrur (Snapper), Carangoides gymnostethus, Carangoides malabaricus, Carangoides ferdau (Carangids), Cephalopholis sonnerati, Epinephelus coioides (grouper), Lethrinus ornatus and Plectorhinchus gibbosus (sea bream). Fishermen, local whole sale buyers, small fish-stall owners and fish consumers were part of respondents. It was observed that there was no difference at statistically significant level (P < 0.05) between infested and healthy fish samples in terms of nutritional profile like protein, fat, ash, carbohydrates and mineral nutrients level. Based on the feedback and information obtained from respondents in the present study found that no incidence of health issues or risk associated with food fishes infested with Ostracoda Vargula tsujii (local name – Arattlai) or any other true parasites.

Full textAbstract:
This work had as objective to study the distribution and abundance of the Carangidae larvae and to analyze the influence of the hydrological (temperature and salinity) and biological factors (phytoplanktonic biomass and zooplanktonic biomass), on the space and temporal distribution of the larvae. Ichthyoplankton was collected during four expeditions from the Northeast Exclusive Economic Zone. Six species (Trachurus lathami, Decapterus punctatus, Chloroscombrus chrysurus, Selene setapinnis, Selene vomer and Elagatis bipinnulata) and Caranx- Carangoides complex were identified. D. punctatus was the species most abundant (52% of the total), with higher abundance during the Period 3, while the Period 2 was the period of low abundance. C. chrysurus was the second species in abundance representing 30% of the total of carangid. This species had higher abundance during the Period 2 and the Period 1. However, in Period 3 abundance were lesser. The third species in abundance was T. lathami that corresponded 8% of the total of carangid larvae. S. setapinnis, S. vomer and E. bipinnulata were the species less abundant, representing together 2% of the total identified larvae. The larvae of Caranx- Carangoides complex represented 9% of the carangid total.

Full textAbstract:
Bigeye scad (Selar crumenophthalmus) is one of the small pelagic economical species from the family of Carangidae. The annual landing of Carangids in Ambon Island sharply dropped in 2018. Meanwhile, demand for these fish has increased following the local population growth. Was the reduction of fish products showing an indication of overfishing? To answer this, we measured the maturity of bigeye scad caught in Ambon waters during east monsoon (May to July 2019 and March to June 2020), including the length-frequency distribution. We found that the minimum size was 5 cm, the maximum (Lmax) was 23 cm, and the optimum length (Lopt) was 18.7 cm. The estimated length of first maturity (Lm) of bigeye scad was 18.3 cm. This study showed that the optimum length was slightly longer than maturity length. Less than 30% of the catch of bigeye scad was immature and indicated a small probability of recruitment overfishing. Arround 57% of megaspawner found during this study showed more robust broodstocks to produce survival larvae into the population. The possibility of overfishing is relatively low for the bigeye scad fishery during the east monsoon, except for the reduction in the maturity size should be concerned.

Full textAbstract:
The skipjack tuna (Katsuwonus pelamis) is a mesopredator fish species with seasonal abundance in waters off Taiwan. Regional ecological and life-history information has been historically lacking for this species. In recent years, stable isotope analysis (SIA) of carbon and nitrogen has been used to assess predator feeding ecology and broader ecosystem trophic dynamics. This study evaluated comparative skipjack feeding ecology in distinct regions off Taiwan, combining traditional stomach content analysis with SIA of individuals off western (n = 43; 2020) and eastern (n = 347; 2012–2014 and n = 167; 2020) Taiwan. The stomach content analysis showed the most important prey to be ponyfish (Photopectoralis bindus) in western Taiwan and epipelagic squids (Myopsina spp.) and carangids (Decapterus macrosoma;) in eastern Taiwan from 2012 to 2014 and epipelagic carangids (Decapterus spp.) and flying fishes (Cheilopogon spp.) in eastern Taiwan in 2020, suggesting that the skipjack tuna is a generalist predator across regions. In contrast, time-integrated diet estimates from Bayesian mixing models indicated the importance of cephalopods and crustaceans as prey, potentially demonstrating more mesopelagic feeding in less productive waters during skipjack migrations outside the study regions. Skipjack off western Taiwan had a slightly higher estimated trophic position than in the waters off eastern Taiwan, potentially driven by the varying nutrient-driven pelagic food web structures. Skipjack SI values increased with body size off eastern Taiwan but not in western waters, suggesting that opportunistic predation can still result in different predator–prey size dynamics between regions.

Full textAbstract:
Multifactorial sampling designs were used to determine the vertical distribution of ichthyoplankton at multiple temporal and spatial scales in New Zealand. Hypotheses concerning the vertical distribution of fish larvae were tested in the following: depth strata, surface, near-surface, mid-depth and deep, and near the substratum. The consistency of abundance patterns was examined at three sites separated by 2–20 km over 2 months. We also tested for differences in shallow water columns of two depths (20 and 40 m) and both day and night. Although peak abundance of total larval fish was found at upper and lower strata, regardless of total depth of the water column, consistent taxa specific patterns of vertical distribution were also found. Some taxa were most abundant at the surface (e.g. mullids, hemiramphids, and kyphosids), whereas others were found at multiple depths below the surface and throughout the water column, regardless of site, time or depth of water column (e.g. carangids, engraulids, clupeids, scombrids, sparids and pleuronectids). Some taxa were most abundant in shallow water columns (e.g. mullids, tripterygiids and gobiids). Rank abundance by depth stratum for non-surface dwelling species varied among sites and times. Diel vertical movements were detected, some taxa (e.g. clupeids, scombrids and bothids) that were most abundant at the surface at night whereas for other taxa this pattern was more variable (e.g. carangids). We conclude that diel depth-related patterns in shallow water columns will influence interactions among taxa and the importance of different transport mechanisms for larval transport.

A espécie Carangoides bartholomaei, conhecida vulgarmente como guarajuba, pertence à família Carangidae, a qual apresenta alguns dos peixes mais importantes para comercialização. Os indivíduos desta espécie possuem distribuição de Massachussetts (EUA) a São Paulo (Brasil), abrangendo toda a plataforma continental. O presente trabalho teve como objetivo analisar os aspectos biológicos da reprodução e alimentação da guarajuba na plataforma continental de Pernambuco. Os 87 indivíduos amostrados, variando de 24,1 a 43,6 cm de comprimento total, foram capturados com rede de espera demersal de malha entre - nós de 40 mm, com aproximadamente 20 m de comprimento e 2 m de altura. Os peixes foram coletados mensalmente, de janeiro de 2009 a março de 2010, após o desembarque do pescado, na comunidade pesqueira de Brasília Teimosa, em Recife. Para cada amostragem, os indivíduos foram submetidos à biometria, sendo mensurados o comprimento total (CT), o comprimento furcal (CF) e o comprimento padrão (CP), medidos em centímetros (± 0,1 cm); o peso total (PT), o peso da gônada (PG), e o peso do estômago (PE), medidos em gramas (± 0,01g). As gônadas foram fixadas em formaldeído 10% e os estômagos fixados internamente com formaldeído a 4% e, externamente, em formaldeído a 10%. Para a análise da reprodução foram determinadas: as proporções sexuais; a frequência relativa dos estádios maturacionais das fêmeas; o índice gonadossomático (IGS); o fator de condição alométrico; o tamanho de primeira maturação sexual (L50); e a fecundidade total das fêmeas. Para a análise da alimentação foram determinados: o grau de repleção (GR); o grau de digestão (GD); o índice de importância alimentar (IAi); as variações na dieta por sexo, meses e classes de comprimento; e o hábito alimentar. A proporção F:M para o total de indivíduos foi 1:0,58. Microscopicamente as gônadas foram classificadas em imatura, em maturação, matura, desovada e em repouso. O período de desova foi longo, ocorrendo do início do período seco até o início do período chuvoso. A relação peso-comprimento para fêmeas e machos foi significativa, com alometria negativa. O L50 foi de 30 cm de CT para as fêmeas. De acordo com o grau e índice de repleção estomacal e grau de digestão das presas, C. bartholomaei apresentou estômagos com maior quantidade de alimento no período chuvoso, enquanto que, no período seco, os conteúdos estomacais se encontravam mais digeridos. A categoria Actinopterygii apresentou maior contribuição no período chuvoso e entre os indivíduos maiores enquanto que Matéria Orgânica Animal e Decapoda foram mais consumidas no período seco e por indivíduos menores. A espécie caracterizou-se por ingerir principalmente Actinopterygii (IAi% = 51,1), tendo Decapoda (IAi% = 3,8) como categoria acessória na dieta. A espécie, bem como a maioria dos indivíduos da família Carangidae, pode ser considerada carnívora pscívora, com dieta variando entre os sexos e de acordo com os estágios reprodutivos, o que se torna uma estratégia para obter sucesso na reprodução.

Full textAbstract:
This thesis had two overriding aims. The first was to describe the biology of Samson Fish Seriola hippos and therefore extend the knowledge and understanding of the genus Seriola. The second was to uses these data to develop strategies to better manage the fishery and, if appropriate, develop catch-and-release protocols for the S. hippos sportfishery.
Trends exhibited by marginal increment analysis in the opaque zones of sectioned S. hippos otoliths, together with an otolith of a recaptured calcein injected fish, demonstrated that these opaque zones represent annual features. Thus, as with some other members of the genus, the number of opaque zones in sectioned otoliths of S. hippos are appropriate for determining age and growth parameters of this species. Seriola hippos displayed similar growth trajectories to other members of the genus. Early growth in S. hippos is rapid with this species reaching minimum legal length for retention (MML) of 600mm TL within the second year of life. After the first 5 years of life growth rates of each sex differ, with females growing faster and reaching a larger size at age than males. Thus, by 10, 15 and 20 years of age, the predicted fork lengths (and weights) for females were 1088 (17 kg), 1221 (24 kg) and 1311 mm (30 kg), respectively, compared with 1035 (15 kg), 1124 (19 kg) and 1167 mm (21 kg), respectively for males. Despite these differences, female and male S. hippos attained similar maximum age, i.e. 29 (1470 mm FL) and 28 years (1280 mm FL), respectively. The maximum age determined for S. hippos is greater than that recorded for any other Seriola spp. The largest female and male S. hippos recorded during this study were encountered during the tagging component and had fork lengths of 1600 mm and 1380 mm, respectively.
Seriola hippos has a protracted spawning period, ca four months, which starts in late spring and continues through summer into early autumn during which time many individuals engage in large spawning aggregations on the lower west coast of Australia. The length at which 50 % of the females in the population reached maturity was 831 mm FL (888 mm TL) and approximately 4 years of age, whilst all females over 950 mm FL were mature. Whilst aggregated for spawning S. hippos ceases feeding, however, during the non-spawning period this species can best be described as an opportunistic carnivore which feeds on a variety of pelagic and demersal prey.
This study has greatly increased our understanding of S. hippos movement on the west and south coasts of Australia and has documented, for the first time, the migratory behaviour of a carangid in these waters. Many S. hippos individuals undertake long distance migrations to join spawning aggregation sites near Rottnest Island. Individuals tagged at these aggregation sites where recaptured throughout this species distribution along the south coast of Australia, some after travelling distances of over 2400 km. Many S. hippos individuals displayed strong temporal and spatial spawning ground fidelity as numerous fish released at the spawning aggregations were recaptured at the exact same spawning site at similar times in subsequent years. Tagging data suggest that on the completion of spawning S. hippos individuals return to a resident location and remain in that general vicinity over the winter months.
This study has developed a hypothesis describing larval dispersal associated with the S. hippos spawning behaviour exhibited near Rottnest Island. It is proposed that variations in the prevailing ocean currents, at this important spawning location throughout the protracted spawning period, leads to high intra and inter-annual variation in larval distribution and survival. The affect of this variation on the evolution of the spawning and migratory behaviour displayed by S. hippos is discussed.
A recent increase in the popularity of S. hippos as a catch-and-release sportfish has led to concerns by some anglers about post release survival of this species, particularly due to the depth of capture. Short term mortality of S. hippos capture at the sportfishing sites was assessed by monitoring fish held within an enclosure near the site of capture for up to 31 hours post release. The total hooking mortality of S. hippos subjected to catch-and-release angling within the Rottnest Island sportfishery is approximately 8%. Most of this observed mortality is delayed and occurs sometime after release. Although best handling practises require ongoing development, the current level of mortality associated with this catch-and-release fishery is considered acceptable. Furthermore, this mortality is likely to have little effect on the S. hippos population due to the high abundance of this species and the fact that even the highest fishing effort yields a relatively low catch. Seriola hippos exhibits a typical teleost neuroendocrine stress response associated with catch-and-release. The physiological dysfunction associated with the stress of capture in this species does not appear to cause any post release mortality. Instead, most mortality was attributable to barotrauma, however, although mortality in S. hippos increases with capture depth, this species is much less susceptible to depth induced mortality than other commonly targeted species in which barotrauma has been observed.
This study developed key handling protocols for fishers who catch-and-release S. hippos at the Rottnest Island aggregation sites. These protocols cover aspects of catch-and-release fishing such as hook type, water depth, time at surface, release method and shark predation.
Almost all S. hippos observed during capture from deep water released large quantities of gas from the opercular region, particularly during the last 10 to 20 m before reaching the surface. This phenomenon has also been witnessed by divers and fishers to occur under natural conditions. Investigations into this release of gas revealed this physoclistous species to exhibit unique swim bladder characteristics. Seriola hippos possess a membranous tube that connects the posterior-dorsal surface of the swim bladder internally to a region under each operculum externally. This connection, termed the swim bladder vent, allows the escape of expanding swim bladder gases on rapid ascent. The presence of the swim bladder vent provides an explanation as to why the incidence of external barotrauma symptoms in S. hippos captured from the deepwater was low. The ability to expel excess swim bladder gases during rapid ascent whilst retaining full swim bladder function is likely to offer this semi-pelagic species considerable advantages when hunting prey, avoiding predators and engaging in spawning activities.
Preliminary estimates of total mortality indicated that S. hippos is not currently subjected to a high level of fishing pressure. However, managers must remain mindful of the fact that the size at which females reach sexual maturity, i.e. 888 mm TL, is greater than the current minimum legal length, i.e. 600 mm, and thus fishers are currently allowed to harvest sexually immature fish. Furthermore, the effectiveness of future conservation measures must consider the large scale migration and spawning strategy undertaken by this species in order to ensure its protection.
The collaborative research approach undertaken during this study demonstrated that a high level of community engagement produced a large amount of research interest, increased stakeholder satisfaction from project input, improved understanding of research outcomes, and increased research uptake, all of which has led to increased stewardship and conservation of the S. hippos fishery and fisheries resources in general. Indeed, projects of this nature would not be possible without this type of approach.

This study developed key handling protocols for fishers who catch-and-release S. hippos at the Rottnest Island aggregation sites. These protocols cover aspects of catch-and-release fishing such as hook type, water depth, time at surface, release method and shark predation.
Almost all S. hippos observed during capture from deep water released large quantities of gas from the opercular region, particularly during the last 10 to 20 m before reaching the surface. This phenomenon has also been witnessed by divers and fishers to occur under natural conditions. Investigations into this release of gas revealed this physoclistous species to exhibit unique swim bladder characteristics. Seriola hippos possess a membranous tube that connects the posterior-dorsal surface of the swim bladder internally to a region under each operculum externally. This connection, termed the swim bladder vent, allows the escape of expanding swim bladder gases on rapid ascent. The presence of the swim bladder vent provides an explanation as to why the incidence of external barotrauma symptoms in S. hippos captured from the deepwater was low. The ability to expel excess swim bladder gases during rapid ascent whilst retaining full swim bladder function is likely to offer this semi-pelagic species considerable advantages when hunting prey, avoiding predators and engaging in spawning activities.
Preliminary estimates of total mortality indicated that S. hippos is not currently subjected to a high level of fishing pressure. However, managers must remain mindful of the fact that the size at which females reach sexual maturity, i.e. 888 mm TL, is greater than the current minimum legal length, i.e. 600 mm, and thus fishers are currently allowed to harvest sexually immature fish. Furthermore, the effectiveness of future conservation measures must consider the large scale migration and spawning strategy undertaken by this species in order to ensure its protection.
The collaborative research approach undertaken during this study demonstrated that a high level of community engagement produced a large amount of research interest, increased stakeholder satisfaction from project input, improved understanding of research outcomes, and increased research uptake, all of which has led to increased stewardship and conservation of the S. hippos fishery and fisheries resources in general. Indeed, projects of this nature would not be possible without this type of approach.

Full textAbstract:
Three stocks of the Cape horse mackerel, Trachurus trachurus capensis, have been recognised in the ICSEAF convention region off southern Africa (Figure 1) on the basis of catch distribution and biological analyses. They were identified as being off Namibia (ICSEAF Divisions 1 . 3 and 1.4), off the West Coast of South Africa (Div. 1.6) and off the South Coast (Div. 2.1 and 2.2). Recently, speculation as to the accuracy of the classification of the South African populations has arisen. The aim of this study was to determine the number of stocks In Divisions 1.6, 2.1 and 2.2, using methodology which assessed the spatial and temporal nature and the phenotypic and genotypic characteristics of the species. The distribution of horse mackerel was evaluated by studying the trends in catch data and length frequency distributions obtained from the demersal industry during 1986 to 1988 and from the demersal biomass cruises in 1987 and 1988. Adult fish, found in Div. 2.1 and 2.2, probably migrated; during the months in which horse mackerel were expected to spawn, CPUE values were higher over the central Agulhas Bank than in the east of the study region. During the quiescent period, catches and numbers were higher in the latter region. Juvenile horse mackerel were found in the nursery areas utilised by pelagic fish and it is likely that they were transported northward from the Agulhas Bank. A decrease in biomass of individuals in Div. 1.5 indicated a separation between a northern and a southern population. Analyses of the phenotype, or epigenetic characters, of horse mackerel were used as a further test of stock integrity. Monthly samples were drawn from Div. 1.6, 2.1 and 2.2 during May 1988 to June, 1989. Comparisons for the values obtained from growth, length-at-50%-maturity and the season of otolith ring formation from each region showed no significant variation in the phenotype. Morphometric analysis proved inconclusive. Monthly gonadosomatic indices show that fish south of the Orange River share the same spawning season. Reports from the literature show that horse mackerel in the latter region differ from those of northern Namibia in spawning season, age-at-50%-maturity and season of otolith ring formation. The genetic structure of the populations of horse mackerel was evaluated by means of a restriction enzyme analysis of the Mitochondrial DNA of 37 fish collected from Divisions 1.4, 1.5, 1.6, 2.1 and 2.2. Two composite genotypes of horse mackerel were found; one belonging to fish in Div. 1.4 and one to fish in Div. 1.6, 2.1 and 2.2. The genetic distance between the two genotypes, 0.07, was the expected distance between two populations at a subspecies level. Fish in Div. 1.5 consisted of both genotypes and may be a region of mixing between the two populations. The interpretation of results was cautioned; prevlous work has shown that the migration of a small number of individuals between two stocks can be expected to maintain a low variation between the populations. In concluding, it was recommended that the horse mackerel be managed as two stocks, one in Div. 1.3 and 1.4 and one in Div. 1.6, 2.1 and 2.2

A família Carangidae Rafinesque 1815 (Teleostei: Percomorphacea: Carangiformes) é tradicionalmente reconhecida como um grupo monofilético, tanto em hipóteses baseadas em dados moleculares quanto morfológicos. O monofiletismo do grupo, entretanto, é sustentado por um baixo número de sinapomorfias e suas relações internas ainda apresentam conflitos. O status filético e inter-relações das tribos Trachinotini,Scomberoidini, Naucratini e Caranginivariam de acordo com autores e metodologias empregadas na reconstrução evolutiva da família. As propostas morfológicas mais recentes para os Carangidae datam de 30 anos atrás e empregam maciçamente dados de morfologia externa e osteologia, sendo a miologia do grupo praticamente inexplorada. O presente estudo analisou extensamente a miologia facial, gular e das nadadeiras peitorais, pélvicas e caudal dos Carangidae e grupos proximamente relacionados. Novos caracteres de origem miológica foram levantados e analisados sob um paradigma cladístico em conjunto com os demais caracteres morfológicos disponíveis na literatura especializada. Uma nova hipótese filogenética foi proposta e comparada com as disponíveis, tanto baseadas em dados morfológicos como moleculares. Os novos dados miológicos reforçam as hipóteses de monofiletismo das tribos de Carangidae, bem como a presença de dois grandes clados irmãos, um formado por Trachinotinie Scomberoidinie outro por Caranginie Naucratini. O estudo da musculatura também forneceu pistas sobre o posicionamento do historicamente problemático gênero Parastromateus dentro de Carangini. Além disso, a descrição de complexos musculares nunca antes estudados forneceu dados sobre o a evolução de músculos considerados erráticos em Percomorphacea e que podem contribuir para o entendimento das inter-relações deste grande grupo.The Carangidae Rafinesque 1815 (Teleostei: Percomorphacea: Carangiformes) is traditionally recognized as a monophyletic group in both morphological and molecular hypotheses. The monophyly of the family, however, is supported by a surprisingly low number of synapomorphies and the internal resolution of the group is contentious. The phyletic status and interrelationships of the tribes Trachinotini, Scomberoidini, Naucratini, and Carangini vary across different studies. The most recent morphological hypothesis for carangids dates back to 30 years and is based solely on data from osteology and external morphology. The myology of the family remainednearly unexplored. The present study analyzed the facial, gular,pectoral, pelvic, and caudal muscles of carangids and closely related outgroups. Several characters from myology were discovered and analyzed under a cladistic paradigm. The new myological data were combined with the morphological data available in the literature in order to produce more robust and up to date phylogenetic hypotheses. The four traditional carangid tribes are herein recognized as monophyletic and the family is basally divided into two major sister clades: one comped by Trachinotini and Scomberoidini and another by Carangini and Naucratini. Also, the historically problematic genus Parastromateus was allocated intoaapical clade within the Carangini. The study of the fin musculature provided insights on the occurrence of muscles considered erratic across the Percomorphacea. Those new discoveries might be helpful for a better understanding of the phylogenetic relationships of thatlarge group.

Full textAbstract:
Various aspects of metabolism and physiology were investigated during the ontogeny of yellowtail kingfish (Seriola lalandi), a fish of growing aquaculture importance in both New Zealand and other countries. Incubation experiments between 18-24°C showed that developing eggs and larvae were heavily influenced by temperature. It appeared that at warmer temperatures larvae hatched smaller but grew on the yolk sac, whereas at cooler temperatures larvae grew inside the chorion. Oxygen consumption data supported this, with a negative correlation found between total embryonic oxygen consumption and temperature. A mechanism was proposed to explain the differential effect of temperature on ontogeny and growth. Like other marine fish with pelagic eggs, yellowtail kingfish were found to be heavily reliant on free amino acids as a source of energy. At 23°C the pattern of substrate utilisation in eggs was considerably different from that at 17-21°C, indicating that 23°C exceeded the tolerance for normal development. Inter-individual aggression by large individuals was associated with the development of size heterogeneity in juveniles. Although this aggression also affected the survival of smaller juveniles, it was not the primary agent of much of the mortality that occurs during this phase, as many of these individuals were on a degenerate developmental trajectory. Yellowtail kingfish fingerlings used for ongrowing were robust to the stressors imposed by live transport. The ontogenetic development of metabolic rate from 0.6 mg-2.2 kg did not follow the same scaling exponent as that observed for mammalian models of allometry, and has implications for interspecific studies of mass-dependent metabolism.

Este trabalho teve como objetivo o estudo dos hábitos alimentares de três espécies de peixes da família Carangidae, da zona de surf da enseada de Caraguatatuba, São Paulo. Amostras de Selene setapinnis, Selene vomer e Oligoplites saliens foram obtidas com rede de arrasto de porta, mensalmente, entre maio de 2003 e outubro de 2004, em duas áreas previamente selecionadas na enseada, com profundidade variando entre 1 e 5 metros. Foram medidos e pesados 3022 exemplares, e 1367 estômagos foram retirados para a análise de conteúdo estomacal. A composição da dieta foi analisada por meio das frequências de ocorrência, numérica, gravimétrica, e volumétrica, e de índices alimentares. Todos os exemplares eram jovens e a sua dieta foi composta principalmente por Crustacea. Outros grandes grupos presentes foram Chaetognatha e Teleostei. Dentre os crustáceos, destacaramse as larvas de Decapoda, os misidáceos, os camarões Acetes americanus e os copépodes calanóides Labidocera fluviatilis e Acartia lilljeborgii. As variações intraespecíficas da dieta, bem como as relações interespecíficas, foram avaliadas através de análises de agrupamento. Foi observada uma tendência de aumento do tamanho da presa com o aumento do tamanho do peixe. Embora A. americanus tenha sido importante na dieta em todos os tamanhos, nas três espécies, houve maior destaque desse item nos peixes maiores, enquanto Lucifer faxoni e larvas de Decapoda foram mais importantes nos menores. Avaliando-se o comportamento alimentar, há indicações de que as três espécies tendem a ser generalistas e a explorar o hábitat de maneira semelhante. Em relação à variabilidade temporal, as espécies diferiram entre si: S. vomer, não apresentou diferença intra-anual significativa, ao contrário de S. setapinnis e O. saliens.The purpose of this work was to study the food habits of three Carangidae juvenile fish species, from the surf zone in Caraguatatuba sound, São Paulo. Samples were taken monthly, with an otter trawl, from May 2003 to October 2004, in two areas previously selected in the bay, between 1 and 5 meters deep. Weight and length of 3002 specimens were taken, and 1367 stomach contents were examined. The diet composition was analyzed through frequencies of occurrence, number, weight and volume, and feeding indexes. The main food item was Crustacea, particularly Decapoda larvae, Mysidae, the shrimp Acetes americanus, and the calanoid copepods Labidocera fluviatilis and Acartia lilljeborgii. Chaetognatha and Teleostei were also present. Seasonal and ontogenetic variations of the diet and interspecific interactions were performed by similarity measures. Ontogenetic changes in diet were recognized; smaller fish consumed smaller prey, and the prey size increased with the body size. Though Acetes americanus were the main item of all sizes, it was more important in bigger fish, while Lucifer faxoni and Decapoda larvae were more important in smaller ones. Selene setapinnis and Oligoplites saliens showed temporal food variability, but Selene vomer did not. The three species were considered as generalists showed similarity in feeding habits.

Previous issue date: 2007-02-27Cytogenetics analyses in fish are important because they compose a private group among the vertebrates, occupying a central position in the animal evolution. The Perciforms Order, dominant in the marine and freshwater environment, it constitutes a model potentially useful in the genetic evaluation of populations, as well as in the understanding of its evolutionary processes. In spite of this, cytogenetics studies in this great group is scarce, above all for the inhabitants of sandy bottom and pelagics habits. The present work proposed to contribute for the cytogenetic characterization of nine species of fish marine of sandy bottom of the coast of Rio Grande do Norte (Brazil), identifying the evolutionary patterns related to the karyotype in these species and the existence of filogenetics affinities between them and other Perciformes. The animals were collected in the beaches of the Redinha, Ponta Negra and B?zios (Coast of Rio Grande do Norte) and in Saint Peter and Saint Paul Archipelago. Later on they were submitted to the cytogenetics technical that consist of mitotic estimulation, obtaining of mitotics chromosomes, proceeded by techniques of conventional coloration (Giemsa) and chromosomic bands (Ag-RONs and C band). Diploid number and fundamental number equal to 48 were observed in most of the species: Menticirrhus americanus, Ophioscion punctatissimus, Pareques acuminatus (Sciaenidae); Chloroscombrus chrysurus (Carangidae); Echeneis sp. 2 (Echeneidae); Archosargus probatocephalus (Sparidae) and Orthopristis ruber (Haemulidae). Trachinotus goodei (NF=52) (Carangidae) and Echeneis sp. 1 (Echeneidae) (NF=54) presented variation in NF, staying constant a diploid number equal to 48. RONs was situated in pericentromeric position in whole the scianids, and in the species Echeneis sp. 2 (22? pair), O. ruber and A. probatocephalus (1? pair), coinciding with great heterocromatics blocks in M. americanus (1? pair), P. acuminatus (2? pairl) and O. ruber (1? pair). RONs was also located in the telomeric area of the short arm of the 5? and 11? acrocentrics pairs in T. goodei, 4? and 19? pairs of C. chrysurus, 1? pair (sm) of Echeneis sp. 1. The C band detected centromeric blocks in most of the chromosomes of the species of Sciaenidae, Carangidae and Echeneidae, with great blocks in A. probatocephalus (4? pair). Heterocromatic blocks in telomeric areas in submetacentrics of Echeneis sp. 1, and pericentromerics in M. americanus (1? and 8? pairs), O. punctatissimus (1? pair) and P. acuminatus (2? pair) were also observed. It is noticed a marked conservatism cromossomic in the species of the family Scianidae and Haemulidae in what says respect to the number of acrocentrics chromosomes and the location of RONs. Even so it is outstanding the presence of heterocromatinization events during the karyotypic evolution of this family. Already in the families Sparidae and Carangidae, the obtained results reaffirm examples of small variations structural resultants of inversion and translocation Robertsonian, as important mechanisms of diversification karyotipical, as well as a pattern numerical evolutionary conserved, also observed in representatives of Echeneidae of Atlantic in relation to Pacific. The presence of RONs multiple, observed in the species T. goodei and C. chrysurus seems to represent a character derived in the family Carangidae. The results for the species O. ruber and A. probatocephalus suggest the presence of possible geographical or climatic barriers among populations of NE of Brazil in relationship the one of the SE

Trachinotus goodei (NF=52) (Carangidae) e Echeneis sp. 1 (Echeneidae) (NF=54) apresentaram uma varia??o no NF, mantendo-se constante um n?mero dipl?ide igual a 48. As RONs estavam situadas em posi??o pericentrom?rica em todas os scian?deos, e nas esp?cies Echeneis sp. 2 (22? par), O. ruber e A. probatocephalus (1? par), coincidindo com grandes blocos heterocrom?ticos em M. americanus (1? par), P. acuminatus (2? par) e O. ruber (1? par). As RONs tamb?m foram localizadas na regi?o telom?rica do bra?o curto do 5? e 11? pares acroc?ntricos em T. goodei, 4? e 19? pares de C. chrysurus, 1? par (sm) de Echeneis sp. 1. O bandamento C detectou blocos centrom?ricos na maioria dos cromossomos das esp?cies de Sciaenidae, Carangidae e Echeneidae, com grandes blocos em A. probatocephalus (4? par). Blocos heterocrom?ticos em regi?es telom?ricas em submetac?ntricos de Echeneis sp. 1, e pericentrom?ricas em M. americanus (1? e 8? pares), O. punctatissimus (1? par) e P. acuminatus (2? par) tamb?m foram observados. Nota-se um marcante conservadorismo cromoss?mico nas esp?cies da fam?lia Scianidae e Haemulidae no que diz respeito ao n?mero de cromossomos acroc?ntricos e a localiza??o das RONs. Por?m ? destacada a presen?a de eventos de heterocromatiniza??o durante a evolu??o cariot?pica desta fam?lia.

A presen?a de RONs m?ltiplas, observadas nas esp?cies T. goodei e C. chrysurus parecem representar um car?ter derivado na fam?lia Carangidae. Os resultados para as esp?cies O. ruber e A. probatocephalus sugerem a presen?a de poss?veis barreiras geogr?ficas ou clim?ticas entre suas popula??es no NE do Brasil, quando comparada com a regi?o SE

Species of the Carangidae family are important components of fish fauna during all phases of the life span. Both Selene spixii (full moon fish) Spix and Agassiz (1831) and Selene Vomer (Atlantic look down) Linnaeus (1758) range in the Western Atlantic Ocean from New Scotia (Canada) to South America including the Gulf of Mexico. They are found in coastal shallow waters, either on hard or sandy bottoms. They usually establish schoals, but are also observed in small groups or pairs. They feed on small crustaceans, shrimps, fish and worms. Their flesh tastes good; these species are trade fresh. They can also be reared, they are highly prized in sport fishing. Both species are very similar in early phases of their life cycle, which renders the identification at the species level quite difficult. The aim of the present study was to carry out analyses of the pattern of morphological differentiation between the above mentioned species of Selene genre, using as method 1, techniques of multivariate analysis of the 16 distances between landmarks, defined in the truss net; and as method 2, the relative warps analysis (thin plate spline function) on the coordinates of 9 landmarks. Morphometric data were obtained from scanner digitalized images and the coordinates of the landmarks by using tpsdigw program, the distances were obtained from a program developed in language C and the relative warps analysis from tpsRelw program. Similarities were discriminated between the studied species using both Principal Components Analysis, Canonic as well as Discriminant Analyses based on morphometric features. The landmarks usedwere: 1. tip of the nose, 2. base of pelvic fin, 3. beginning of the first dorsal fin, 4. beginning of anal fin, 5. beginning of the second dorsal fin, 6. end of anal fin, 7.end of the second dorsal fin, 8. beginning of lower caudal fin, 9. beginning of upper caudal fin. According to method 1, measures D 1-3 and D 3-4 were the most important whereas for method 2, among shape variations, the one which contributes the most was the component x.
Os Carangidae são importantes componentes da ictiofauna em todas as fases da vida e as espécies Selene spixii (Lua-do-Caribe) Spix e Agassiz (1831) e Selene vomer (galo–de-penacho) Linnaeus (1758) estão distribuídas pelo Atlântico Oeste de Nova Escócia (Canadá) ao longo das costas do Golfo do México até a América do Sul. Esses peixes são encontrados em águas rasas costeiras, sobre fundos duros ou arenosos. Vivem em cardumes, mas também podem ser observados em pequenos grupos ou em pares. Alimentam-se de pequenos caranguejos, camarões, peixes e poliquetas. Sua carne apresenta um sabor excelente, sendo comercializado fresco. Estes peixes podem ser cultivados em aquários, são valorizados na pesca esportiva, e ambas espécies apresentam grande semelhança na fase jovem o que dificulta a identificação. O objetivo deste trabalho foi analisar os padrões de diferenciação morfológicos entre as espécies do gênero Selene, utilizando como método 1, técnicas de análise multivariada das 16 distâncias entre marcos anatômicos, definidas na rede de treliças; e como método 2, a análise de deformações relativas (função thin plate spline) sobre as coordenadas de 9 marcos anatômicos. Os dados morfométricos foram obtidos em imagens digitalizadas por scanner, as coordenadas dos marcos anatômicos pelo programa tpsDig, as distâncias obtidas por programa desenvolvido em linguagem C e a análise de deformações relativas através do programa tpsRelw. Pretendeu-se discriminar similaridades entre as duas espécies por meio de Componentes Principais, Análise de Variáveis Canônicas e Análise Discriminante com base em características morfométricas. Foram utilizados os seguintes marcos anatômicos: 1. ponta do focinho; 2. base da nadadeira ventral (pélvica); 3. início da primeira nadadeira dorsal; 4. início da nadadeira anal; 5. início da segunda nadadeira dorsal; 6. final da nadadeira anal; 7. final da segunda nadadeira dorsal; 8. início da nadadeira caudal inferior; 9. início da nadadeira caudal superior. No método 1, as medidas D 1-3 e D 3-4 foram as mais importantes, enquanto que no método 2, dentre as variações de forma, a que mais contribuiu foi a componente uniforme x.

Full textAbstract:
Fish assemblages as reflected from coastal land use in mangrove estuary of Ban Laem District, Phetchaburi Province, Inner Gulf of Thailand had been conducted seasonally during December 2012 and October 2013. Samplings were conducted in blood cockle farms, public benefit channel, mangrove fringe area and Ban Laem estuary, using a push net at both day and night. A total of 29,287 individuals belonging to 11 orders 33 families and 54 species were collected. The Carangidae was by far the most speciose (6 species), with Arius maculatus numerically dominating (15,989 individuals, 54.59%). The highest number of individual was recorded in mangrove fringe area (21,051 individuals, 71.88%) in May (18,642 individuals, 63.65%) at day catches (22,149 individuals, 75.63%). The highest value indices of diversity, richness and evenness were 2.59, 3.65 and 0.88 respectively, recorded in mangrove fringe area in October. ANOSIM analysis showed a clearly significant difference of species compositions and abundance among sites, seasons and between day and night (p=0.001). Catches consisted primarily of juveniles or small-sized fishes, indicating that the area is important as a nursery ground. The findings of this study have implications for the conservation and management of mangrove and fisheries resources in Ban Laem and adjacent areas in the inner Gulf of Thailand.
