Abstract:

Mullet is the most heavily fished species in Tunisia, accounting for one-third of the freshwater fish harvest. To ensure the continuity and development of fisheries in the country, Tunisian reservoirs have been stocked with Mugilidae fry collected from coastal and estuarine areas. The quantities of fry introduced and mullet landings were correlated. To determine the spatial distribution and abundance of mullets in these fisheries, a multi-mesh gillnet was used in 10 reservoirs. The results showed a weak global correlation between the fry introduced and mullet landings, while the correlation of these variables in each reservoir separately revealed a high correlation in all the reservoirs, except for Ghezala reservoir. The fishing survey revealed that the numerical yield varied significantly from one reservoir to another. Sidi Saad reservoir recorded the highest yield of mullet (196.52 fish/1000 m2 of nets), while a lower yield was recorded in Lahjar, Seliana, Mellegue, Laabid, Ghezala, Bezirekh, Bouheurtma, Sidi Salem, and Sidi Barrak reservoirs. The harvested mullets’ sizes ranged from 14 to 65 cm, indicating good growth conditions in the Tunisian reservoirs. Our findings demonstrate a high potential for mullet production in the country; therefore, we recommend the sustainable development of this sector.

Abstract:

The flathead gray mullet (Mugil cephalus L.) is a cosmopolitan fish that lives in warm and temperate zones over 42°N–42°S. It is a key fish species for industrial fishing off coastal Taiwan. Gray mullets enter the coastal waters of the southeastern Taiwan Strait (22°N–25°N) to spawn in winter and feed in the coastal and tidal waters of China (25°N–30°N). From 1986 to 2010, the annual catch of gray mullet decreased substantially and remained low. Although the Pacific Decadal Oscillation and El Niño–Southern Oscillation are recognized to affect gray mullet migration, the increase in sea surface temperature may be the main cause of the aforementioned decrease. We explored how weather changes affect fishing conditions and patterns at the gray mullet fishing grounds in Taiwan’s coastal areas. Because of the decrease in gray mullet catches, the most common method for catching gray mullet in Taiwan’s coastal areas between 1990 and 2010 was the use of drift or trawl nets instead of two-boat purse-seiner fleets. Since 2012, purse-seiner fleets have become the most common method for catching gray mullet. This trend indicates that the local fishing industry is adapting to changing environmental conditions.

Abstract:

This study involved 334 specimens of mullet, Mugil platanus, captured monthly in the estuarine region of Cananéia, São Paulo State, Brazil, from July 1988 to June 1989, and examined for the presence of gill parasites. Parasitological inspections revealed the occurrence of the following groups: Trichodina sp., Monogenoidea, Copepoda, and Hirudinea. Only four mullets were not parasitized. Total weight and total length of all 334 mullet specimens examined were used for adjusting the weight-length relationship curve and calculating the relative condition factor (Kn). The 118 specimens infested with monogenoideans on average had lower weights than expected (Kn < 1.0), and the 81 fish co-infested with Copepoda, Monogenoidea, and Trichodina sp. showed a Kn < 1.0. The other infested and non-infested mullets had a Kn > 1.0. It was possible to infer that gill infestation with monogenoideans alters mullet weight, especially in the presence of co-infestation with Trichodina sp. and copepods.

Abstract:

Redlip mullet (Chelon haematocheilus) is distributed in coastal waters of the North-Western Pacific Ocean and is a cultured fish in Korea. A hydroacoustic technique constitutes a useful method to assess the biomass and spatial distribution of mullet in sea cages or in coastal waters, and acoustic target strength (TS) information of the target fish is an essential parameter in using this method. In this study, ex situ TS measurements of 16 live mullets were made in an aquaculture sea cage in Korea. The split-beam scientific echo-sounder used for measurements was comprised of 38, 120, 200, and 420 kHz frequencies. An underwater video camera was simultaneously used to observe the mullets’ behavior during the TS measurements. The mullet TS data was analyzed from a wide range of total fish length (FL: 14.3–40.3 cm). As results for all frequencies, the frequency dependence of the mean TS values were relatively low, and the difference in mean TS was within 2.5 dB. When the slope of the least-squares regression line was forced to 20 into the TS equation, the resulting value for the constant term (b20) at each frequency was −67.0 dB, −68.3 dB, −66.3 dB, and −68.5 dB, respectively. The data tended to be frequency dependent. Additionally, the maximum TS appeared between tilt angles of 0° and 10°. These results indicate that TS measurements can be applied to estimate the biomass of the mullet in sea cages or in coastal waters.

Abstract:

Based on biological and meteorological long-term database (1979-1983 and 1996-2000), we analyzed the variation in the juvenile recruitment and artisanal fishery landings of the mullet (Mugil platanus) in the Patos Lagoon estuary and its relationships with the regional rainfall and estuarine salinity anomalies during two strong El Niño events (1982-83 and 1997-98). Juvenile and adult mullets declined in abundance under the high rainfall and near-zero salinity that prevailed in the estuary during both El Niño events. We proposed two different hypotheses to explain the El Niño-induced effects on the juvenile and adult stages of the mullet in the estuary. First, high freshwater outflow during a very strong El Niño might render ineffective the mechanism of passive immigration of juvenile mullets into the estuary, which can lead to their decline in the estuary during El Niño events. Second, near-zero salinity at the estuarine area along several months during strong El Niño events could lead to higher spatial dispersion of the maturing mullet during their migration to the ocean , resulting in smaller shoals of individuals and, consequently, lower catches by artisanal fishermen.

Abstract:

Different lagoon grey mullets such as Liza ramada (thinlip mullet), Liza aurata (golden grey mullet), and Liza saliens (leaping grey mullet) were analyzed for their nutritional, microbiological, and safety parameters. The microbiological values never exceeded the lower limits stipulated by the Italian Higher Institute of Health. The pathogenic species frequently associated with seafood (Salmonella, Listeria monocytogenes, Vibrio cholerae, Vibrio parahaemolyticus, and Aeromonas hydrophila) were never detected. The absence of coliforms and of Escherichia coli was noted in all fish species after 4 days of storage in ice. Heavy metals such as cadmium and mercury were always below the detection limits (0.01 mg/kg). All three fish species had low levels of total biogenic amines (80 to 100 mg/kg), and the presence of histamine was sporadic. All Liza species, particularly L. ramada and L. saliens, are a good source of Ω3 long-chain polyunsaturated fatty acids.

Abstract:

We report on the interaction between common bottlenose dolphins, Tursiopstruncatus (Montagu, 1821) and cast net fishermen in southern coast of Brazil. The fishery was monitored in the mouth of the Tramandaí River Estuary to investigate the seasonality of catches and their relationships with a set of variables: presence/absence and number of bottlenose dolphins, fishing area, temperature, salinity, wind and water flow direction in the channel. The mullet, Mugilliza Valenciennes, 1836 is the target species and was the dominant fish in the catches (77% of total catch; 50% in frequency; 0.2 ind. x f-1). The use of GLM models helped to reveal that the number of the bottlenose dolphins, time of year (months) and spatial variation of fishing activity were the main factors explaining the presence and abundance of mullet in the fishermen’s catches. The presences of bottlenose dolphins in the fishing area raise the probability of fishermen catch larger number of mullets with smaller fishing effort. However, the size of the mullet is influenced basically by seasonality. The mullets are the “currency” of bottlenose dolphins and fishermen interaction. There are reasons for concern about the sustainability of the southern Brazilian M.liza stock, once the decrease of this fishing resource can lead this rare and traditional fishery to the extinction.

Abstract:

This research investigates local ecological knowledge of fishers in communities along a latitudinal gradient in the coast of the Santa Catarina State, regarding the life cycle of mullets Mugil liza (migration, feeding, and reproductive behavior). Our sampling encompassed eight Santa Catarina coastal cities (nine artisanal fishing sites) and engaged 45 key informants (28- 86 years of age) through semi-structured interviews from August/2011 to March/2012. This fish species feeds and grows in lagoon and estuarine systems, migrating to the sea for reproduction, and spawning. Fishers acknowledged the Patos Lagoon and the Plata River as the main source of mullet schools. Migration occurs from South to North and the routes vary according to climatic and oceanographic conditions (e.g., low temperatures, south winds, rainfall, currents, salinity). These conditions influence the abundance of mullets (and therefore fisheries success), their migration and stops in locations such as beaches, rocky shores, and islands. According to fishers, mullet spawning occurs throughout the coast of the Santa Catarina State and they feed in lagoons and riverine systems but also out at sea during migration. In conclusion, fishers possess a detailed knowledge about mullet life cycle and they identify intra and interannual variations in migration routes, a pattern that should be considered in managing the fishery.

Abstract:

The study was conducted to determine the diversity and abundance of mullets (Mugilidae) in the New Calabar River, Nigeria. Fish samples were collected monthly between February to July 2018 at three landing stations: Choba: Station 1, Ogbogoro: Station 2 and Iwofe: Station 3. A total of 578 individuals belonging to three species (Sicklefin mullet (Neochelon falcipinnis Valenciennes, 1836), Largescaled mullet (Parachelon grandisquamis Valenciennes, 1836) and Flathead grey mullet (Mugil cephalus Linnaeus, 1758) of the family Mugilidae were sampled. N.falcipinus recorded the highest abundance (47.40%) followed by M.cephalus (36.85%) while P.grandisquamis recorded the least abundant (15.74%). The Simpson’s index of diversity had the highest value of 0.63 in Choba station and the least value of 0.59 in Iwofe station, while the Simpson’s reciprocal index highest value of 1.71 in Iwofe station and least value of 1.60 in Choba station. The Shannon- Weiner index and Pielou’s eveness index value also recorded highest values of 1.03 and 0.94 in Choba station with the least values of 0.96 and 0.87 in Iwofe station respectively. The diversity indices showed that the family Mugilidae is fairly distributed in the study area and it is therefore recommended that further research should be carried out to provide a complete examination of the biology and ecology of the mullets within the New Calabar River.

Abstract:

As it is common in tropical and temperate zones, mullet species constitute the most important fish species caught along the coast and estuaries of Turkey. In terms of ecology, tourism and and fish productivity (52 kg/ha), Koycegiz-Dalyan Lagoon Ecosystem (KDLES) is the most important lagoon, with a 5500 ha surface area, is the Mediterranean Coast of Turkey. In the dalyan (barrier fish trap) systems; approximately 225 tons (80-405 tons) of mullets are caught to obtain 5 tons of dried fish eggs per year. Seventy percent of fish production in the lagoon is composed of mullets. The mullet samples were collected monthly between October 1992 and September 1994 from eight stations (one of them is a marine station) by trammel nets. The ages were determined using by scales anda ge composition varied form 0 to 6 ages. Species composition of 1159 sampled individuals were proportionally determined as Mugil cephalus 45%, Liza aurata 35%, Liza saliens 14%, Liza ramada 12%, Chelon labrasus 6%. The growth performance indices calculated from von Bertalanffy growth parameters using by all individuals for the M. cephalus, L. aurata, L. saliens, L. ramada and C. labrasus were determined as 2.957, 2.866, 2.692 and 2.719, respectively. The highest growth performance index was calculated for M. cephalus. The growth performance indeces of mullet species in Köyceğiz-Dalyan Lagoon Ecosystem were found around the world averages.

Abstract:

Aim of study: To describe the common behaviour of flathead grey mullet (Mugil cephalus) under rearing conditions. Area of study: Tepic, Mexico. Material and methods: Behaviours exhibited by mullets were videorecorded with submersible cameras installed inside of three tanks. A total of 690 min per day (07:30 - 18:30 h) were recorded per tank during a week. Afterwards, the different behaviours exhibited by juvenile M. cephalus were described, identified and characterized in an ethogram and grouped into two categories: a) locomotion, including three different observed behaviours (resting, swimming and fast swimming) and b) feeding, including three behaviours (surface feeding, bottom feeding and rubbing). Each of the behavioural variables were quantified. Main results: M. cephalus is a species with a constant locomotion associated to feeding, since fish showed continuous movement during most of day light period. On the contrary, fish exhibited reduced movement during dark periods. Mullets were observed to be a non-aggressive fish species under conditions of the present study, since the absence of dominance and aggression towards conspecifics was observed, which suggested a high predisposition for adaptation to captivity. Finally, behavioural frequencies of grey mullet juveniles were similar among the three tanks for most of the behavioural variables analysed (p>0.05) except for the variable bottom feeding (p=0.02). Research highlights: Results from this study could be of interest for the aquaculture industry to optimize rearing techniques and welfare for the production of grey mullet.

Abstract:

For more than a century of active commercial exploitation and environmental changes in the Caspian Sea, the structure of the population of marine fish species has undergone significant qualitative and quantitative changes. In this group of fish until 1960, the main role in the fishery was played by sea herring, which provided up to 50–70% of the total fish catch in the region. Interest in the study of marine fish of the Caspian Sea, using the example of mullets, Black Sea acclimatizers, is due to the fact that under new conditions, as well as a result of deep negative changes in the ecology of this reservoir under the influence of natural and anthropogenic factors, especially recently. At present, among marine fish, one of the main and promising fishing objects is mullet, which, since the period of acclimatization, has formed a high abundance in the coastal zone of the Daghestan coast of the Caspian Sea. Mullet are euryhaline fish that can live both in sea, salty water, and freshwater bodies. In this regard, the objects of this study were mullet (singil), the study of their commercial catches and stocks in the Caspian Sea.

Abstract:

Myxobolus ichkeulensis is one of the species fish parasites within the class Myxozoa that infests the gill filaments of grey mullet (Mugil cephalus). M. ichkeulensis infestation rates vary depending on environmental conditions and seasonal variations. In this research, seasonal infestation ratio of M. ichkeluensis on Grey Mullets living in 4 different environmental conditions, were determined. To accomplish this aim, 25 Grey Mullet individuals were captured monthly from 4 different stations (Karataş Port, Hurma Boğazı Lagoon, Çamlık Lagoon and Yumurtalık Port) within the coastal region of Adana province. In addition, relation between infestation ratio and the following parameters: fish size (length and weight); season and salinity were investigated. Our results revealed that, 109 fish infested out of 1200 fishes (%9.08) by M. ichkeulensis; Highest infestation level (%35.8) was recorded in summer months (July-September) interval. Parasitic cyct settlement on the gill arches was determined to be with the highest rate (48.2%) on the fist arc. The highest infestation level (21%) was recorded in Grey Mullets captured from Yumurtalık Port in comparison to other stations studied.

Abstract The aim of the present study was to evaluate the potential use of otolith microchemistry (Sr:Ca and Ba:Ca ratios) to identify silver mullet, Mugil curema, populations in Southeastern Caribbean Sea. Fish samples were collected in 7 areas of Nueva Esparta State (Venezuela). The otolith Sr:Ca and Ba:Ca ratios and water Sr:Ca were determined (by ICP-OES and EDTA volumetric method). Otoliths Sr:Ca and Ba:Ca ratios and Sr:Ca partition coefficient of mullets in Cubagua island (south of the State) were significantly different from ratios in La Guardia (north of the State). A discriminant analysis of otolith Sr:Ca and Ba:Ca ratios separated Cubagua Island from La Guardia values. These results suggest the existence of different mullet groups in the Southeastern Caribbean Sea. For this, the simultaneous use of Sr:Ca and Ba:Ca ratios could be a potential tool to identify populations in the study area.

Abstract:

The mullets are a widespread group of ecologically and economically important fishes of disputed taxonomy due to their uniform external morphology. Barcoding and phylogenetic studies from various locations around the world largely highlighted the species diversity underestimation using morphological criteria used to establish the taxonomy of the family. Here, we investigated the mullet species diversity from Pakistan, a biogeographic area where nearly no mullet species were genetically characterized. Morphological examination of 40 mullets reveals 6 known species (Planiliza macrolepis, P. klunzingeri, P. subviridis, Crenimugil seheli, Ellochelon vaigiensis, and Mugil cephalus). Using a references DNA barcode library, the DNA barcode-based species identification flagged eight molecular operational taxonomic units (MOTUs) belonging to five genera (Crenimugil, Ellochelon, Mugil, Osteomugil, and Planiliza). Among these MOTUs, only one was already present in Barcode of Life Data system, all other representing new Barcode Index Numbers (BIN). These results emphasize the importance of the recognition of cryptic species and the necessity to re-evaluate the overall diversity by the genetic characterization of different species of this family. DNA barcoding is an effective tool to reveal cryptic species that need to be considered in conservation and management measures of fisheries in Pakistan.

Abstract:

In this study, aliphatic hydrocarbon levels were investigated in red mullet and european hake fish caught by trawler from Edremit Bay (Western Aegean, Turkey) in spring and autumn 2015. For this purpose, trawling was carried out from 3 different regions of the Edremit Bay in both seasons. As a result of the analyzes, total aliphatic hydrocarbon (TAH) levels in red mullet were found to be higher than that of european hake. TAH concentrations found for red mullet were in the range of 456-2090 ng/g, while it was found in the range of 61-746 ng/g for european hake. In general, TAH concentrations in red mullet were higher than that of european hake for both seasons. In addition, EOM amounts were found higher in red mullet like TAH. According to correlation, cluster and primary component analysis results, it was observed that the compounds affecting TAH levels in red mullet are C11 and C12 aliphatic hydrocarbon compounds, while european hake have C15, C17 and Pristane compounds. These results indicate that the source of aliphatic hydrocarbons in Edremit Bay fish is biogenic in european hake samples, although not exact, it may be petrogenic in red mullet samples.

Abstract:

AbstractFour new actinospore types belonging to the sphaeractinomyxon collective group (Cnidaria, Myxosporea) are described from the coelomic cavity of a marine Baltidrilus sp. (Oligochaeta, Naididae) inhabiting a northern Portuguese estuary. Host identification supports the usage of marine oligochaetes, namely of the family Naididae Ehrenberg, 1828, as definitive hosts for myxosporeans inhabiting estuarine/marine environments. The absence of mixed infections in the host specimens analysed is suggested to reflect the influence of host-, parasite- and environmental-related factors regulating myxosporean–annelid interactions. Molecular analyses matched the SSU rDNA sequences of three of the four new types with those of mugiliform-infecting Myxobolus spp., namely Myxobolus mugiliensis and a Myxobolus sp. from flathead grey mullet Mugil cephalus, and Myxobolus labrosus from thicklip grey mullet Chelon labrosus. These results directly link, for the first time, the sphaeractinomyxon collective group to a myxospore counterpart, further confirming their previously hypothesized specific involvement in the life cycle of myxobolids that infect mullets. Acknowledging this life cycle relationship, the functionality of the sphaeractinomyxon morphotype is suggested to have been decisive for the evolutionary hyperdiversification of the genus Myxobolus in mullets. Unlike other actinospore morphotypes, sphaeractinomyxon lack valvular processes, which implies a limited capability for buoyancy. Considering the benthic-feeding nature of mullets, this feature is most likely crucial in promoting successful transmission to the vertebrate host.

Abstract:

Mullets (Mugilidae) present significant potential for sustainable aquaculture diversification due to their eurythermal, euryhaline, and low-trophic nature. However, the physiological differences and optimal cultured conditions among the diverse mullet species are quite unknown. For these reasons, the present study aimed to address two main objectives: (1) to characterize the differences in digestive biochemistry, somatic indexes, and body composition between two mullet species (Liza aurata and Chelon labrosus); and (2) to evaluate the interactions of two different feeding frequencies (one against three meals per day) on the above-mentioned parameters, and also on the potential bioavailability of nutrients determined using in vitro assays. The results evidenced higher protease and amylase activities for Chelon labrosus than for Liza aurata, while the latter species presented a higher percentage of eviscerated weight and muscle lipids. Furthermore, the results from in vitro assays supported the higher enzyme activity of Chelon labrosus by an observed increase in the release of amino acids and reducing sugars measured for this species. Regarding feeding patterns, the results of the in vitro assays simulating enzyme: substrate (E:S) ratios corresponding to one or three meals per day point to a clear increase of nutrient bioavailability when the daily ration is split into several meals. The present results improve the physiological knowledge of mullet species and define criteria to develop better management protocols by producers.

Abstract:

Catadromous fish species often use elevated flows to migrate from freshwater to downstream spawning grounds. However, in regulated river systems, artificial barriers and flow alteration can disrupt movement cues, affecting fish migration. Using a combination of acoustic telemetry, passive integrated transponder (PIT) tags and gonad maturity data, we assessed the migratory timing and flow requirements for downstream spawning migrations and upstream dispersal in two co-occurring mullet species in the Logan River, eastern Australia. Over 4 years, 141 adult sea mullet (Mugil cephalus) and 28 adult pinkeye mullet (Trachystoma petardi) were implanted with acoustic transmitters and broad-scale movements tracked using an array of 49 acoustic receivers. Juvenile upstream dispersal was monitored using implanted PIT tags and readers deployed in weir fishways. Sea mullet and pinkeye mullet undertook large-scale downstream migrations from February to March. Movements past weirs only occurred once sufficient flow had occurred and, in the case of pinkeye mullet, when gonads were mature. In contrast, juvenile dispersal into upstream habitats occurred primarily between November and April on low flows. This study advances our understanding of bidirectional movement ecology and flow requirements of two co-occurring mullet species to inform environmental flow management (e.g. to facilitate fish passage) in a regulated river system.

Abstract:

Waste from industrial activities can be a source of pollution for the waters of Banten Bay. One source of these pollutants are heavy metals. High concentrations of heavy metals in waters can pollute the aquatic environment, endangering all organisms. Heavy metals can accumulate in aquatic environments and living organisms such as fish. The greenback mullet Planiliza subviridis (Valenciennes, 1836) is known as a fish for human consumption. Heavy metals that are contained in mullets can move to a higher trophic level within the food chain and endanger the health of humans. This study aims to analyze the accumulation of heavy metals, such as Hg, Cd, Pb, and Cu, in the flesh of greenback mullets at Bojonegara Waters of Banten Bay. The research was carried out for five months (August - October 2020 and March - April 2021). Samplings were taken from Terate River and Wadas River, which are mullet fishing areas and natural habitats of these mullets. Data analysis consisted of descriptive and quantitative analyses. The results showed that the Hg, Cd, Pb, and Cu contents were below the quality standards based on Government Regulation of the Republic of Indonesia (PP RI) No. 22 of 2021. The greenback mullets have experienced a moderate accumulation rate. The different rates of Cu metal accumulation in each month indicate a variation in catches with low to moderate accumulation rates. The water conditions in Bojonegara can still be seen as tolerable and still suitable for mullets usable for human consumption in a reasonable amount. Monitoring and evaluation activities need to be carried out periodically for the management of the aquatic environment in Bojonegara.

Abstract:

We studied the relative catch performance of a modified trawl fitted with an extension piece using a 90º turned mesh (T90) in comparison with a standard trawl net used in NW Mediterranean bottom trawl fisheries employing a diamond mesh net. The comparison was made by means of paired experimental hauls using the same fishing vessel with alternate deployments of the standard net (control) and the experimental net. We used the catch comparison approach for three target species of the fishery: European hake, red mullet and striped red mullet. Our results show that the experimental net significantly reduces the catches of small-size hake and red mullet (though there was no discernible difference for striped red mullet), reducing unwanted catches of regulated species under the Landings Obligation. The overall catch rates of hake, pooled over all sizes, also increased by an estimated 50%, while the catch rates of red mullet and striped red mullet were significantly lower. However, considering all commercial species, the experimental net produced losses of commercial catch and income estimated at 17% and 18%, respectively, which may pose a barrier to the adoption of this relatively simple, inexpensive solution.

Abstract:

Bottarga is a high-priced delicacy with high nutritional value, and, in Italy, bottarga from mullets has been recognized to be a traditional food product. The flathead grey mullet Mugil cephalus and the thinlip grey mullet Liza ramada are the main cultured grey mullets in the Mediterranean Sea. In this study, fresh roe and bottarga from these two species were investigated to evaluate the influence of the technological process and the species on their biochemical composition and health advantages. The 1 h/200 g salting-out step did not increase the levels of NaCl in the bottarga, although it highly decreased the levels of some heavy metals like Cu and Al. Processing of fresh roe in bottarga led to an essential modification of the lipid fraction, following a general series of monousatturated fatty acid (MUFA)> poliunsutturated fatti acid (PUFA) > saturated fatty acid (SAFA) and an increase in both ω3 and ω6 in Liza ramada. Moreover, bottarga showed higher levels of squalene and cholesterol and an increased Essential Amino Acid/Total Amino Acid ratio (EAA/TAA) in both species. In addition to the nutritional benefits for the consumer, the process proposed in this study may represent a reliable tool for local producers to obtain a final bottarga with both a reproducible biochemical composition and organoleptic characteristics.

This study objectives is to determine the content of heavy metals Pb and Cd in water as well as in the Mullet Fish (Mugil cephalus) and Orange Spotted Rabbit Fish (Siganus guttatus) caught in Benoa Bay. The study was conducted from February to April 2018. The results showed that the content of heavy metals Pb and Cd in the water in Benoa Bay had exceeded the quality standards of metals dissolved in water for marine biota listed on Pergub Bali No. 16 of 2016. The value of Pb heavy metals in Mullet Fish and Orange Spotted Rabbit Fish in some samples have exceeded the maximum limit of heavy metal contamination SNI 7387: 2009. Cd heavy metal in Mullet Fish and Orange Spotted Rabbit Fish have exceeded the maximum limit of Cd metal contamination in fish and the processed product of 0.1 mg / Kg. Bioconcentration factor of metal Pb in Mullet Fish is included in the category of low accumulative properties of Pb heavy metals. BCF value of metal Cd in Mullet Fish shows that Mullet Fish has moderate accumulative properties against heavy metal Cd. Orange Spotted Rabbit Fish belongs to low category of accumulative properties against heavy metals Pb and Cd.

Abstract:

Understanding the spatiotemporal persistence of fish distributions is key to defining fish hotspots and effective fisheries-restricted areas (FRAs). Hierarchical Bayesian spatiotemporal models provide an excellent framework to understand these distributions, as they can accommodate different spatiotemporal behaviour in the data, primarily due to their flexibility. The aim of this research was to characterize the fundamental behavioural patterns of fish as persistent, opportunistic or progressive by comparing different spatiotemporal model structures in order to provide better information for marine spatial planning. To illustrate this method, the spatiotemporal distributions of 2 sympatric Mullidae species, the striped red mullet Mullus surmuletus and the red mullet M. barbatus, were analysed. The occurrence of each species, its conditional-to-presence abundance and median length were analysed using Mediterranean trawl survey data from the western Mediterranean between 2000 and 2016. Results demonstrate that there are various common hotspots of both species distributed along the Iberian coast. The convenient persistent spatiotemporal distribution of these hotspots facilitates the configuration of a network of connected FRAs for red mullets in the study area.

Therefore, it was described maturation and induced spawning of mullet (Mugil liza) breeders born in captivity (F1). F1 males presented viable sperm at 11 months of age, with length of 25.7 ± 0.4 cm and weight of 205.7 ± 11.5 g. In contrast, at three years of age F1 females could be reproduced, with length of 47.4 ± 1.4 cm and weight of 1263.0 ± 64.6 g. Ten spawnings were conducted, and the average diameter of the oocytes at the time of hormonal induction, fertilization rate, total and relative fertility and hatching rate were recorded. Spawning was attained through hormonal induction in females with oocyte diameter greater than 600 µm and in males that released semen with abdominal massage. During this reproductive period, induced females produced a second group of mature oocytes so another hormonal induction was performed. The present study describes the induction of mullet breeders born in captivity and the possibility of females to be induced more than once during the same reproductive period.

Abstract:

The present work evaluated the quality and freshness characteristics and the effect of modified atmosphere packaging (MAP) on the shelf-life extension of refrigerated Mediterranean mullet using microbiological, biochemical, and sensory analyses. Fresh open sea red mullet (Mullus surmuletus) were packaged in four different atmospheres: M1, 10%/20%/70% (O2/CO2/N2); M2, 10%/40%/50% (O2/CO2/N2); M3, 10%/60%/30% (O2/CO2/N2); identical fish samples were packaged in air. All fish were kept under refrigeration (4 ± 0.5°C) for 14 days. Of the three gas atmospheres, the 10%/40%/50% (M2) and 10%/60%/30% (M3) gas mixtures were the most effective for inhibiting growth of aerobic microflora in mullet samples until day 10 of refrigerated storage. H2S-producing bacteria and pseudomonads were part of the mullet microflora and their growth was partly inhibited under MAP conditions. Between these two bacterial groups, H2S-producing bacteria (including Shewanella putrefaciens) were dominant toward the end of the storage period, regardless of the packaging conditions. Brochothrix thermosphacta and lactic acid bacteria were found to be members of the final microbial flora of MAP and air-packaged mullet, whereas the Enterobacteriaceae population was lower than other bacterial groups. Of the chemical freshness indices determined, thiobarbituric acid values were variable in mullet samples irrespective of packaging conditions indicative of no specific oxidative rancidity trend. Based on sensorial data and aerobic plate count, trimethylamine nitrogen and total volatile basic nitrogen limit values in the range of ca. 15 to 23 and 52 to 60 mg N/100 g of fish muscle were obtained, respectively, for mullet packaged under modified atmosphere and air. Sensory analyses (odor and taste attributes) showed that the limit of sensorial acceptability was reached after ca. 6 days for the samples packaged in air, 8 days for the M1 and M3 samples, and after 10 days for the M2 samples. Respective shelf-life extension for fresh whole mullet was ca. 2 days (M1 and M3 gas mixtures), and 4 days (M2 gas mixture).

Abstract:

High levels of heavy metals in seawater deputize a warning for public health and environment. The purpose of the study was to monitor and evaluate the concentration levels of heavy metals in edible sample tissue of Red mullet. A total of 40 of muscle sample tissue of Red mullet purchased directly from the local fresh fish market of Tirana was utilized to determine by using atomic absorption spectrophotometer (AAS). The results of the study showed that mercury (p=0.049) and lead (p0.001) concentration levels varied significantly between samples of Red mullet with different weights. According to the results concentration level of mercury and lead measured in muscle samples tissue resulted below the maximum permitted levels for human consumption set by EC legislation. High levels of cadmium made an exception (0.44 mg/kg wet weight). The results of the monitoring study give relevant information on heavy metal contamination of fish species with commercially interest such a Red mullet. The results of the monitoring process suggest that Red mullet should be object of further monitoring with the goal to protect Tirana consumer’s health from heavy metals contamination

Abstract:

The following three species of grey mullet (Mugilidae) are recorded by Wheeler (1978) for the waters of north-western Europe: thick-lipped mullet, Chelon labrosus (Risso, 1826); thin-lipped mullet, Liza ramada (Risso, 1826) and golden mullet, Liza aurata (Risso, 1810). Liza ramada was obtained in relatively large numbers during the course of extensive sampling of the material collected on the intake screens of power stations in the Bristol Channel and Severn Estuary (for details of other studies see e.g. Claridge & Gardner, 1977, 1978; Titmus, Claridge & Potter, 1978; Abou-Seedo & Potter, 1979; Claridge & Potter, 1983, 1984). Since there is apparently no detailed information on the biology of the thin-lipped mullet in the estuaries of north-western Europe based on regular frequent collections, the power station material was used to provide data on seasonal and annual abundance, size composition, growth and lip depth of this species in the Severn Estuary and Bristol Channel. Comparisons have been made between these data and those obtained for C. labrosus from the same environments and more particularly from outside the area at Pembroke where much larger collections of this latter species were taken.

Abstract:

The study was carried out to observe growth, production and profit of prawn, stripped mullet (Mugil cephalus) and corsula mullet (Rhinomugil corsula) at different stocking ratio under polyculture in the Bagerhat district for four months. The experiment was designed as a randomized block design and had three treatments based on stocking ratio with three replicates in each treatment. Juveniles of prawn (Macrobrachium rosenbergii) and fingerlings of fin fishes (stripped mullet and corsula mullet) were stocked at a stocking ratio of 3:1:1, 4:1:1 and 5:1:1/m2 in T1, T2 and T3, respectively. Prawn and fin fishes were fed with a commercial diet and farm made formulated feed on a daily basis. Recorded water quality parameters were within suitable ranges of prawn and fish culture. Higher growth (43.0 g) of the prawn was achieved in T1 followed by T2 (41.0 g) and T3 (38.0 g), but prawn growth was not significantly different between T1 and T2. The growth and survival rate of prawn, stripped mullet and corsula mullet were lower in T3, where the stocking ratio was higher. Higher production of the prawn was obtained in T2 (1148.0 kg/ha) than those of T1 (954.6 kg/ha) and T3 (1083.0 kg/ha). But significantly (p<0.05), higher production of stripped mullet was found in T1 (650.0 kg/ha) and T2 (579.5 kg/ha) than T3 (500.5 kg/ha). Similarly, higher production of corsula mullet was found in T1 (850.0 kg/ha) and T2 (834.9 kg/ha) than T3 (719.8 kg/ha). However, combined production and net profit of prawn and fin fish farming were significantly (p<0.05) higher in T2 (2562.4 kg/ha, BDT 277,384.51/ha) followed by T3 (2303.3 kg/ha, BDT 229,693.95/ha) and T1 (2454.6 kg/ha, BDT 179,393.31/ha). So from a production and economic point of view, polyculture of prawn and fin fish at a stocking ratio of 4:1:1/m2 is more profitable compared to other stocking ratios and this system may be suggested to disseminate at coastal farmers’ level.

Abstract:

Salted fish preparations are popular and widely eaten across the world. Salting is a preservation strategy to enhance shelf life by decreasing water activity in fish muscles. Salted fish demand increases with less regard for preservation characteristics, and novel strategies are required for healthy production. Lysozyme, EDTA, their mixture, and black cumin oil nanoemulsion (BCN) were used for dipping treatments to make preservative films before salting. A medium-sized mullet were classified into six groups: fresh, commercial salted mullet, and four treatments. Stored salted mullet groups were evaluated for chemical composition changes, lipid profile changes, nitrogen profile changes, and microbial contamination. The results were reflected by nonsignificant changes in protein content (21.08 ± 1.05%) of the BCN compared to the fresh (22.41 ± 1.41%), with the lowest salt penetration to the flesh (11.11 ± 0.74%). The lowest value recorded was the BCN for the pH (5.53 ± 0.06) and water activity (0.447 ± 0.019). The changes in lipid profile compared to the fresh were very low, which does not happen in a commercial salted sample. The changes in total volatile and non-protein nitrogen represented very low for the BCN compared to the commercial salted one. Coliform, E. coli, Staphylococcus aureus, Salmonella, and Clostridium were not detected in the BCN salted mullet. The overall acceptability for the BCN mullet was the best in the test panel list evaluation, followed by the mixture treatment. This research indicated that the BCN treatment before mullet fish salting was optimal, with greater food safety properties and no consumer acceptance alterations.

Abstract:

Common bottlenose dolphins co-exist with artisanal fisheries in the Asinara Island National Park area (northwestern Sardinia, Italy) and are blamed for damage to some fisheries. To investigate this, two T-POD echolocation loggers were used between July 2003 and October 2004 to monitor the occurrence and behaviour of dolphins in the proximity of three different fishing gear types. With the support of local fishermen, the T-PODs were opportunistically deployed on trammel nets set for striped red mullet or for lobster and on bottom traps set to catch benthic fish species. Inter-click Intervals (ICI) and the Pulse Repetition Frequency (PRF) have been adopted as indicators of dolphins echolocation behaviour in the proximity of fishing gears (Leeney and Tregenza, 2006). PRF values were found to be consistently higher in proximity to trammel nets for striped red mullets compared to the other gears. Moreover, ICI values in the proximity of red mullet trammel nets were found to be statistically lower than those recorded both around trammel nets for lobster (p<0.01) and around traps (p<0.01). These findings suggest that feeding related activities by dolphins could be absent or take place at very low levels in the proximity of traps and, to a lesser extent, in the proximity of trammel nets set for lobster, but may occur more regularly around nets for striped red mullet. The results show that static acoustic monitoring can detect significant differences in dolphin echolocation behaviour around different fishing gears. The findings seem to be consistent with previous evidence of interactions between bottlenose dolphins and fishing gear types in the area.

Abstract:

A brief but detailed observation which Aristotle made regarding the foraging behavior of the red mullet (Mullus surmuletus) is examined closely in order to better understand the substance of the discussion. Aristotle's description of the heterospecific red mullet/sea bream foraging behavior is evaluated in light of contemporary observations and life history characteristics. Possible methods, including underwater observations with the use of diving equipment and observations in fish ponds, employed by Aristotle in making these observations are discussed. I also speculate on the ways in which the red mullet/sea bream interaction might be thought of as gregarious behavior according to Aristotle.
