Abstract

The golden mussel (Limnoperna fortunei), a mollusc originating from Asia, has caused considerable environmental and economic damage in various Brazilian river basins and reservoirs. Genetic studies that focus on characterizing its invasive potential and the feasibility of control measures are required. The present study identified and characterized 13 new microsatellite markers (of which eight were polymorphic) in L. fortunei using enriched genetic libraries. The analysis performed on 48 individuals from three populations identified 32 alleles, ranging from one to seven alleles per locus. The size of the fragments ranged from 172 to 381 bp. The polymorphic information content values ranged from 0.114 to 0.768, with observed and expected heterozygosity values ranging from 0.043-0.938 to 0.123-0.805, respectively. Six loci showed significant deviation from the Hardy-Weinberg equilibrium, possibly influenced by the heterozygous deficit. The microsatellite primers developed will be useful in studies of the genetic diversity and population structure of L. fortunei and will also contribute to the adoption of control measures for this invasive species in Brazilian and other South American basins. KEY WORDS: golden mussel, genetic diversity, population structure, mollusc, primers, SSR, Limnoperna fortunei, INTRODUCTION The golden mussel Limnoperna fortunei (Dunker, 1857) is a bivalve mollusc of the Mytilidae family, with origins in Southeast Asia, mainly from China (Rtickert et al. 2004), and is [...]

Abstract

AbstractHybrid cachapinta (Pseudoplatystoma reticulatum × Pseudoplatystoma corruscans) has been a very popular fish and is well accepted by consumers internationally, however, there is a lack of information showing its advantages relative to its parental cachara (P. reticulatum) species. This study was undertaken to compare the processing yield and meat quality characteristics of cachara and the cachapinta hybrid raised in net cages. Cachara’s weight was 1.51 ± 0.27 kg and total length was 49.85 ± 6.22 cm at harvest and was not significantly different from hybrid cachapinta that weighed 1.50 ± 0.11 kg and measured 50.83 ± 3.91 cm. Additionally, the two groups were not statistically different on gutted fish dress out (cachara: 89.97 ± 1.28%; cachapinta: 90.23 ± 0.30%) and other processing yield parameters. Skinless shank fillets with an average weight of 503.77 ± 0.10 g (cachara) and 514.41 ± 0.04 g, (hybrid cachapinta) were evaluated for pH, water holding capacity, colour (L*, a*, b*), shear force and lipid oxidation (TBARS). There were no differences in the fillet meat quality between cachara and hybrid cachapinta tested in this study. In conclusion, both genetic groups had similar processing yield and fillet meat quality characteristics when produced in net cages.HIGHLIGHTSThe perceived improvements in growth and disease-resistance generated by hybrid vigour are the main reasons for interest and use of hybrid fishes.It is difficult to systematically predict processing yield and meat quality obtained from hybrids.Processing yields and meat quality are similar for cachara and hybrid cachapinta produced in net cages.

Abstract

Jewel tetra (Hyphessobrycon eques) is a freshwater fish found in several rivers and basins in South America. The present study is the first study to create a panel of microsatellite markers for detecting genetic diversity in H. eques and evaluating the application of these markers in Serrapinnus notomelas. In total, 44 individuals were genotyped from the natural (WIL, n = 20) and stock in captivity (CAP, n = 24) population. Moreover, 19 microsatellite markers were obtained, of which only 8 loci presented a high degree polymorphism. In total, 45 alleles were detected, ranging from 126 bp (Hype2G2) to 420 bp (Hype2E2). The Hardy–Weinberg equilibrium (p < 0.05) revealed significant difference in one locus in WIL (Hype1G4) and three loci in CAP (Hype1F4, Hype2C3, and Hype2G2). Null alleles (p < 0.05) were present in only one locus (Hype1G4). The WIL and CAP populations revealed high genetic diversity during FST analysis. The cross-amplification test for S. notomelas revealed that only two loci (Hype2C3 and Hype2G2B) presented satisfactory transferability results. The developed microsatellite primers will be useful in studying the genetic diversity and population structure of H. eques in wild populations and fish farms in the Brazilian and other South American basins.

Abstract

Native fish species in Brazil are an asset in fish farming, but their natural stocks have been significantly reduced in recent years. To mitigate this negative impact, studies on fish conservation are being conducted and genetic tools for the discrimination of population parameters are increasingly achieving great importance. Current analysis evaluates a set of microsatellite heterologous primers in the jundiá (Rhamdia quelen) and in the piapara (Leporinus elongatus). Samples from the caudal fin of 15 broodstock from each species were analyzed. DNA extraction was performed with NaCl protocol and the integrity of the extracted DNA was checked with agarose gel 1%. Twenty primers developed for Piaractus mesopotamicus, Colossoma macropomum, Prochilodus lineatus, Brycon opalinus and Oreochromis niloticus were evaluated. Cross amplification of four primers of the B. opalinus and P. lineatus species (BoM12, Pli43 and Pli60 in R. quelen and BoM2, Pli43 and Pli60 in L. elongatus) was assessed. Primers of P. mesopotamicus, C. macropomum and O. niloticus showed no cross amplification in the two species analyzed. Results revealed the possibility of using the four amplified heterologous primers in genetic studies for R. quelen and L. elongatus. As espécies nativas de peixes no Brasil tem alto potencial para utilização dentro da piscicultura, porém, seus estoques naturais vêm sofrendo redução nos últimos anos. Para diminuir esse impacto negativo, estudos voltados à conservação estão sendo realizados e cada vez mais, a obtenção de ferramentas genéticas que permitam a discriminação de parâmetros populacionais toma maior importância. Objetivou-se através do presente estudo avaliar um conjunto de primers microssatélites heterólogos em jundiá (Rhamdia quelen) e piapara (Leporinus elongatus). Foram analisadas amostras de nadadeira caudal de 15 reprodutores de cada espécie. A extração de DNA foi realizada utilizando o protocolo com NaCl. A integridade do DNA extraído foi checada em gel de agarose 1%. Foram avaliados 20 primers desenvolvidos para as espécies: Piaractus mesopotamicus, Colossoma macropomum, Prochilodus lineatus, Brycon opalinus e Oreochromis niloticus. Foi observada amplificação cruzada de quatro primers das espécies B. opalinus e P. lineatus (BoM12, Pli43 e Pli60 em R. quelen e BoM2, Pli43 e Pli60 em L. elongatus). Os primers de P. mesopotamicus, C. macropomum e O. niloticus não mostraram amplificação cruzada nas duas espécies analisadas. Os resultados indicaram a possibilidade de uso dos três primers heterólogos amplificados em estudos genéticos em R. quelen e L. elongatus.

Abstract

Neste trabalho, os parâmetros seminais de P. mesopotamicus foram avaliados fresco e após criopreservação, com foco nas variáveis espermáticas ​​que afetam as taxas de fertilização, eclosão e os parâmetros pós-eclosão como a sobrevivência e a morfologia das larvas. Os espermatozoides e os ovócitos dos animais foram coletados após a extrusão, e a qualidade seminal e a fertilização dos ovócitos foram analisados. Posteriormente, uma porção de cada amostra de semen foi criopreservada e, após dois dias, os ovócitos de três novas fêmeas foram fertilizados com semen criopreservado dos machos. As análises mostraram que a motilidade progressiva, o vigor espermático, a duração da motilidade, o número de espermatozoides normais e anormalidades secundárias foram maiores no semen fresco do que no semen após descongelamento (P
