Abstract:

The karyological and molecular analysis of four fresh water fish species of Family: Poecilidae and their genetic relationships have been studied. Xiphophorus maculates and Xiphophorus hellerii have the same diploid chromosome number 2n=48, but they were different in their karyotypes. Poecilia sphenops and Poecilia reticulata have the same diploid chromosome number 2n=46 and the same fundamental number FN=46, also the same karyotype one group of acrocentric chromosomes. Nine RAPD primers, showed monomorphic bands, were used for the construction of the dendrogram and a similarity matrix. A total of 65 bands were obtained; 39 of them were monomorphic bands. Similarity values among the studied samples ranged from 21% to 38%. High similarity value was obtained between Xiphophorus maculates and Xiphophorus hellerii. (38%) and the low similarity values were obtained between Xiphophorus hellerii and Poecilia reticulata (21%). The cluster analysis clearly differentiated Xiphophorus maculates and Xiphophorus hellerii from Poecilia sphenops and Poecilia reticulata. RAPD analysis confirmed that the four species under study are genetically different from each other. These cytogenetic data obtained can be applied for further studies in cytotaxonomy and evolutionary relationships of fishes.

Abstract:

The poeciliid species, Poecilia kempkesi Poeser, 2013, was the fourth species of the subgenus Acanthophacelus Eigenmann, 1907 to be described, based on individuals from a single urban anthropized locality close to Paramaribo, Suriname (Poeser, 2013). The description itself lacked any section clearly distinguishing the new species from the remaining species of Poecilia Bloch & Schneider 1801, and in particular from the species of the subgenus Acanthophacelus, type species Poecilia reticulata Peters, 1859. According to Article 13 of the International Code of Zoological Nomenclature (ICZN, 1999) the criteria of availability for a species-group name are:

Abstract:

OBJETIVO: Avaliar a competência de peixes na predação de larvas de Aedes aegypti, em condições de laboratório. MÉTODOS: Foram testados machos e fêmeas de cinco espécies de peixe. Os testes de predação duravam cinco semanas para cada espécie. Cada ensaio compreendia quatro caixas testes e quatro caixas controles. Das caixas controle, duas tinham somente um peixe e as outras duas, apenas larvas. Cada caixa teste continha um peixe e larvas. Na primeira semana foram expostas 100 larvas em cada caixa, e a cada semana acrescentavam-se 100 larvas por caixa/dia, até se obter um máximo de 500 larvas/dia. Comprimento e peso dos peixes foram medidos semanalmente. RESULTADOS: Foram utilizadas 369.000 larvas no total. O Trichogaster trichopteros foi a única espécie em que ambos os sexos predaram 100% das larvas oferecidas. O Betta splendens deixou de predar apenas 15 larvas. Machos do Poecilia reticulata apresentaram baixa capacidade larvófaga quando comparados às fêmeas da mesma espécie. Em relação ao peso e tamanho o Betta splendens mostrou-se capaz de predar 523 larvas/grama/dia. CONCLUSÕES: Fêmeas e machos de Trichogaster trichopteros e de Astyanax fasciatus, e fêmeas de Betta splendens e de Poecillia sphenops foram os peixes que apresentaram maior competência para predar as larvas. Embora com competência menor, machos de Poecillia sphenops e fêmeas de Poecilia reticulata foram capazes de eliminar o número de larvas de Aedes aegypti que possam emergir durante 24 horas num criadouro, em condições naturais. Machos de Poecilia reticulata não foram predadores eficazes.

Abstract:

The research aimed to know the influence of Poecilia reticulata body size, in the feeding capacity on Culex quinquifasciatus larvae. The research was experimental method with Complete Random Design., each treatment with 5 replications. The taken body size of Poecilia reticulata were; 1,50 cm; 2.50 cm; and 3.50 cm. the size of fish's body was measured from the tip of snout up to the end of fin (cm). The feeding capacity was determined by subtracting the first amount of larvae which was given the rest of larvae after 24 hours. The result showed that the difference of size of Poecilia reticulate body was significantly different in the feeding capacity on Culex quinquefasciatus larvae. The fish whose body size was 1.50 cm had the lowest feeding capacity by eating 77.2 larvae for average, and the highest one was the fist which body size was 2.50 cm by eating 113.6 larvae for average, subsequently the feeding capacity decrease to the fish which body size was 3.50 cm because of eating 100,6 larvae for 24 hours.

Abstract:

Poecilia reticulata is a freshwater fish from the northeastern part of South America and spread widely to various countries in Asia and other continents. However, research about P. reticulate is limited even though it is a well-known fish species in Indonesia. The purpose of study was to identify the fish species of P. reticulata through DNA barcoding using the COI gene to determine the phylogenetic relationships among fish populations in East Java, Indonesia. In a present study, there were eight samples of P. reticulata from four different freshwater locations in East Java. Extraction, amplification, and sequencing of DNA samples were conducted to obtain the genetic data and construct a phylogenetic tree based on DNA sequences. The COI gene is the most popular markers to study genetic populations and phylogeography among the animal kingdom. Our phylogenetic reconstruction showed a clear that there were two groups of P. reticulata. The first group was obtain through species from East Java, Sukabumi, West Java (KU692776.1), Dominican Republic, Pandeglang, Banten and Myanmar. The second group was P. reticulata from southern Africa, Brazil, and Sukabumi, West Java (KU692775.1). The result of this study indicate that the guppy fish in East Java identic with P. reticulata from West Java (KU692776.1), which a widely used in classification based on evolutionary relationships. The findings of this study have important implication for the development of advance research about adaptation, phylogeny, and evolution of fish, especially of guppy fish.

Abstract:

In the present work Trichodina reticulata and T. nobilis (Ciliophora: Trichodinidae) are morphologically characterised from ornamental freshwater fish culture in the State of Santa Catarina, Brazil. The prevalence of infection and a list of comparative measurements are discussed. We examined "southern platyfish" Xiphophorus maculatus (n = 35), "goldfish" Carassius auratus (n = 31), "guppy" Poecilia reticulata (n = 20), "sailfin molly" Poecilia latipinna (n = 6), "beta" Betta splendens (n = 2) and "spotted headstander" Chilodus punctatus (n = 1). After being anesthetised in a benzocaine solution, fishes were examined for parasitological evaluation. A total of 51.57% fishes were parasitised by Trichodina spp. Carassius auratus was the most parasitised species, followed by X. maculatus and P. reticulata. Beta splendens, C. punctatus and P. latipinna were not parasitised by any trichodinid species. Two species of Trichodina were collected from the skin of fish: T. nobilis was found in C. auratus, P. reticulata and X. maculatus and T. reticulata was only observed in C. auratus. The importance of adequate handling in ornamental fish culture are also discussed.

Abstract:

The Ogun River is a sink for untreated effluents discharged from the Kara Cow Market, Ogun State. In this study, microbiological, physicochemical and heavy metals evaluation were carried out on effluent from the market. Standard methods were utilised for the examination of physicochemical and microbiological parameters of the effluent. The histological effects of sublethal concentrations of the effluent were assessed in the gills, intestine and skin of Poecilia reticulata (guppy fish) over a period of 56 days following standard methods and international ethical guidelines. None of the physicochemical parameters were within the set limits by the National Environmental Standards and Enforcement Agency (NESREA) for effluent discharges into surface waters. Coliforms, pathogens and fungi were observed in the effluent with a total plate count of 2.14 x 107 cfu/mL. The median lethal concentration (96 h LC50) of the effluent to P. reticulata was 71.50 mL/L (7.15%). Histological alterations such as distorted mucosal architecture with shortening and widening of intestinal villi were observed in the intestine of exposed groups of P. reticulata at day 56. The observed adverse physicochemical parameters, histological alterations and pathogenic microbes may pose ecological and public health risks to aquatic organisms and humans respectively. It is recommended that an effluent treatment plant should be installed at the market to reduce the pollutants load of the effluent before discharge into the Ogun River.

Abstract:

The ever-increasing global trade of ornamental aquarium fishes is one of the most important pathways for aquatic invasion. Occurrence of ornamental freshwater fishes in natural freshwaters has been increasing in recent years. The ornamental trade accounts for a limited but steadily growing proportion of fish introductions to Turkish inlandwaters. In this study, Guppy, Peocilia reticulata, is recorded for the first time from natural inlandwaters of Turkey. P. reticulata was probably released into the wild, but is now established in aquifer of Çeşme-Ildır (İzmir).

Abstract:

Animals gain benefits by forming groups with phenotypically and behaviourally similar individuals. The most common groups are homogenous, composed by conspecifics, although in some cases associations of similar organisms of different species have been reported when individuals benefit from it. In this study, we tested the prediction that the Trinidadian guppy, Poecilia reticulata, a fish that has successfully invaded at least 70 countries, will shoal with heterospecifics. We measured shoaling tendency and shoal companion preference in wild-caught female guppies when they encounter two heterospecific species: the native Poecilia picta and the non-native Poecilia sphenops, a poeciliid recently introduced in Trinidad. Our results show that guppies have a higher tendency to shoal with conspecifics; if the alternative is be alone, they readily shoal with both species even when they have had no previous experience with other poeciliids. Individuals in these associations could benefit from safety in numbers along with other advantages of group living. This predisposition to associate with other species that share similar ecological conditions could explain the guppy’s success as invasive species as it enables them to increase their shoal size during the first stages of invasion and thus avoid Allee effects.

O estudo teve como objetivo promover o levantamento da ictiofauna do lago Jaboti, situado na cidade de Apucarana, Paraná, Brasil. As coletas foram realizadas bimestralmente, entre abril de 2010 e março de 2011, em cinco pontos de amostragem. No total, foram capturados 22.489 indivíduos, distribuídos em cinco ordens, seis famílias e sete espécies. Poecilia reticulata foi a espécie mais representativa em termos de abundância. Esta espécie apresenta adaptações morfológicas e fisiológicas que conferem maior tolerância às alterações ambientais antrópicas. Deste modo, foi constatado que esta espécie pode ser considerada bioindicadora e que o lago Jaboti sofre uma avançada degradação ambiental ao longo de todo o seu perímetro. Ichthyofauna Structure on the Littoral Zone of an Urban Lake in the River Ivaí Basin A survey of the ichthyofauna of the lake Jaboti in the town of Apucarana PR Brazil is undertaken. Collections were done every two months, between April 2010 and March 2011, at five sampling sites. Further, 22,489 specimens, distributed into five orders, six families and seven species were harvested. Poecilia reticulata was the most abundant species, featuring morphological and physiological adaptations with more tolerance to anthropic environmental changes. The species may be considered a bio-indicator since lake Jaboti undergoes a progressive environmental degradation throughout its perimeter.

Abstract:

We investigated the ability to recognize the color of surfaces in fish (Poecilia reticulata), bred from birth in conditions of artificial light with constant spectral content. The capacity for color constancy significantly deteriorated when compared that to the control group. Further alteration of lighting conditions and transfer into natural daylight conditions restored the suppressed function to its normal level. We suggest that the color constancy function belongs in the visual system-response functions, the full development of which requires the accumulation of individual visual experience.

Abstract:

AbstractThis study investigated population differences in the courtship behaviour of male guppies, Poecilia reticulata, in the presence and absence of predators. Two Trinidad populations were compared: the Lower Aripo where guppies occur sympatrically with a range of piscivores and the Upper Aripo where levels of fish predation are low. Upper Aripo males displayed risk-reckless courtship behaviour and did not reduce their sigmoid display rate or otherwise modify their courtship behaviour when threatened by two Astyanax bimaculatus. The courtship behaviour of the Lower Aripo males was, by contrast, risk sensitive. These fish performed a lower proportion of sigmoid displays and increased their level of sneaky mating attempts in the presence of predators. Although males from the two populations used both sneaky and conventional courtship behaviours there were individual differences in the use of the reproductive tactics.

Abstract:

Poeciliid fish, freshwater fish with internal fertilization, are known for the diversity of structures on the male intromittent organ, the gonopodium. Prominent among these, in some species, is a pair of claws at its tip. We conducted a manipulative study of these claws in the guppy, Poecilia reticulata , to determine if these aid in transferring sperm to resistant females. We compared the sperm transfer rates of clawed versus surgically declawed males attempting to mate with either receptive or unreceptive (i.e. resistant) females. Our analyses demonstrate that the gonopodial claws function to increase sperm transfer to unreceptive females during uncooperative matings but not during receptive matings. Up to threefold more sperm were transferred to unreceptive females by clawed than declawed males. These data suggest that the claw is a sexually antagonistic trait, functioning to aid in transferring sperm to resistant females, and implicate sexual conflict as a selective force in the diversification of the gonopodium in the Poeciliidae.

Abstract:

Nitrite is a natural component of the nitrogen cycle in the environment. Although it usually occurs in low concentrations, elevated concentrations caused by effluents or affected nitrification process can lead to serious health deterioration of fish. Two aquarium fish zebrafish (Danio rerio) and guppy (Poecilia reticulata) are recommended to use as model organisms in toxicity tests. However, their sensitivity to nitrite can differ. The aim of this study was to define acute toxicity of nitrite by the semistatic method according to OECD No. 203 (Fish, Acute toxicity test). The series of 4 acute toxicity tests was performed, with 10 fish of both species used for each concentration and for the control. The 96hLC50 NO2- value for D. rerio and P. reticulata was 242.55 ± 15.79 mg·l-1 and 30.2 ± 8.74 mg·l-1, respectively. We have proved significant difference (p < 0.05) in sensitivity between D. rerio and P. reticulata. The results showed different sensitivities to nitrites in tested fish species, which could be related to species-specific branchial chloride uptake mechanism. This is the first study on this fish species.

Abstract:

Studies on fish parasites in Pampulha dam, Belo Horizonte, Minas Gerais, Brazil, found specimens of Poecilia reticulata Peters, 1859 harboring natural infection by larval stages of tapeworms. A total of 250 specimens of P. reticulata were collected and analyzed between February and August 2010, of which 23 were found infected (prevalence 9.2%) with one metacestode each (mean intensity 1, mean abundance 0.09). The analyses of the parasites, particularly the morphology of rostellar hooks, made it possible to identify Glossocercus auritus (Rudolphi, 1818). This is the first report of G. auritus metacestode in South America and P. reticulata is a newly known host for this parasite.

<p>Water temperature could affect the reproduction of broodstock and sex ratio of progeny. In this study, broodstock of guppy (<em>Poecilia reticulata</em> Peters) was reared in different temperature to determine its effect on reproduction of broodstock and sex ratio of their progeny. The result of study show that broodstock reared at 27°C produced more fry (16 males mean) than that of 30°C (10 males), while broodstock reared at 33°C produced no progeny. Percentage of male fish produced by broodstock reared at 30°C is higher than that of 27°C. Incubation time of embryo before birth is sorter in broodstock reared at 30°C (4-12 days) compared with 27°C (18-22 days).

Abstract:

We investigated the presence and possible function of chemical alarm signals (alarm pheromones) in wild Trinidadian guppies (Poecilia reticulata) using laboratory, trapping, and direct field observational methods. In laboratory experiments, female guppies from a population exposed to high predation significantly increased their shoaling, dashing, and freezing behaviours and significantly reduced area use when exposed to the skin extract of sympatric female guppies. When exposed to the skin extract of females from a low-predation population, female guppies from a high-predation population exhibited significant, though smaller, increases in antipredator behaviour. No significant differences in antipredator behaviours were noted when females were exposed to swordtail (Xiphophorus helleri) skin extract, which lacks any known alarm pheromone. We conducted two field experiments to confirm these laboratory results. In a trapping experiment, significantly more guppies were caught in funnel traps labelled with distilled water than in paired traps labelled with sympatric guppy skin extract. In a final experiment, a realistic model of a natural predator (pike cichlid, Crenicichla alta), paired with either sympatric guppy skin extract or distilled water, was presented to groups of free-ranging guppies in pools of a high-predation river. Significantly fewer guppies were observed within a 50-cm radius of the predator model and significantly fewer guppies inspected the model when it was paired with guppy skin extract versus distilled water. Taken together, our results strongly suggest the presence of a chemical alarm signal (alarm pheromone) in the Trinidadian guppy, establish the validity of laboratory and trapping studies in the investigation of chemical alarm signalling, and demonstrate that alarm pheromones may function to mediate predation risk under natural conditions in the guppy.
