Abstract
With the rise of world fish farming, the national scenario is favorable for using native fish for intensive farming. Among the catfish, the Amazonian Jundiá (Leiarius marmoratus) is a robust candidate, easy to grow and with good organoleptic characteristics in its flesh. For productive success in captivity, it is necessary to consider some questions about the species, such as genetic variability, which must have an acceptable level in a breeding stock, in order to maintain a good diversity; this reduces losses due to inbreeding and low diversity. Therefore, the objective of this study was to characterize the genetic variability of commercial stocks of L. marmoratus from the State of Mato Grosso through microsatellite molecular markers. We analyzed 143 individuals from three stocks. The mean heterozygosity and the inbreeding coefficients observed were 0.060; 0.084; 0.141; and 0.539; 0.562; 0.514, respectively, for the stocks of Campo Verde, Juína, and Nova Mutum. The Deviation in the Hardy-Weinberg equilibrium was observed in most of the loci in the three populations. Considering the genetic differentiation, it is concluded that the three populations are very close genetically, which requires introduction of new genetic material in the stocks to enrich them genetically for a later reproductive program.

Abstract
The pacu (Piaractus mesopotamicus) is a Neotropical fish with remarkable productive performance for aquaculture. Knowledge of genetic resources in Neotropical fish is essential for their applications in breeding programs. The aim of this study was to characterize the genetic diversity of seven farmed populations of pacu which will constitute the basis for a broodstock foundation for coming breeding programs in Brazil. Analysis of one wild population (Paraná River) was used as a reference to compare genetic parameters in the farmed populations. The analyses were performed using 32 single-nucleotide polymorphisms (SNP) and 8 simple sequence repeat (SSR) markers. No significant differences in genetic diversity between populations estimated through the number of alleles and allelic richness, observed heterozygosity, expected heterozygosity, and minimum allele frequency were detected (p > 0.05). Low genetic diversity was observed in all farmed stocks and the wild population. Moreover, we detected low genetic structure when comparing farmed and wild populations for SNPs (FST = 0.07; K = 3) and SSRs (FST = 0.08; K = 2). Analysis of molecular variance (AMOVA) demonstrated that genetic variation was mostly within populations. Kinship analysis showed that most fish farms included related individuals at a proportion of at least 25%. Our results suggest that the basal broodstock for pacu breeding programs should be founded with individuals from different fish farms for higher genetic diversity and to avoid inbreeding risks.

Abstract
Utilizaram-se marcadores microssatélites para estimar a diversidade genética de grupos de pacu (Piaractus mesopotamicus) coletados nas escadas de transposição das hidroelétricas de Canoas I (CI) e Canoas II (CII), no Rio Paranapanema, e de um estoque e uma progênie utilizados em programas de repovoamento nesse rio. Os loci microssatélites produziram 16 alelos e heterozigosidade observada média similar entre os indivíduos do rio nos dois tempos de coleta (CI14 = 0,7356; CI28 = 0,7361; CII14 = 0,7442; e CII28 = 0,7507), do estoque e da progênie (0,7261 e 0,7287, respectivamente). Foram observados desvios no equilíbrio de Hardy-Weinberg, e valores negativos do índice de fixação com excesso de heterozigotos que indicaram ausência de endogamia. As análises de diversidade genética (distância e identidade genética, índice de Shannon, F ST e AMOVA) foram indicativas de baixa diferenciação genética e conduziram ao agrupamento dos indivíduos do rio, sugerindo que essa espécie está geneticamente estruturada como uma única população. Foram verificados baixa diferenciação genética e altos valores do número de migrantes entre os indivíduos do rio, do estoque e da progênie, o que presume a origem comum derivada dos constantes repovoamentos realizados nesse rio a partir dessas populações estocadas.

Abstract
Analisou-se a diversidade genética de estoques de reprodutores de Tambaqui (Colossoma macropomum), mediante o uso de marcador RAPD, utilizando-se 10 primers para analisar 30 amostras do estoques de reprodutores das pisciculturas de Boa Esperança e Vale Verde, localizadas no Estado de Rondônia. A porcentagem de fragmentos polimórficos e o índice de diversidade genética de Shannon foram altos nos dois estoques de reprodutores. O estoque de reprodutores de Boa Esperança apresentou um fragmento exclusivo. A diferenciação genética foi baixa e o número de migrantes por geração foi alto entre os estoques de reprodutores. O dendrograma não separou os indivíduos dos estoques de reprodutores em grupos distintos. Há alta variabilidade genética nos estoques de reprodutores, um pouco inferior no estoque de Vale Verde, e há grande proximidade genética entre os indivíduos dos estoques de reprodutores.

Abstract
The Paraná-Paraguay basin encompasses central western Brazil, northeastern Paraguay, eastern Bolivia and northern Argentina. The Pantanal is a flooded plain with marked dry and rainy seasons that, due to its soil characteristics and low declivity, has a great water holding capacity supporting abundant fish fauna. Piaractus mesopotamicus, or pacu, endemic of the Paraná-Paraguay basin, is a migratory species economically important in fisheries and ecologically as a potential seed disperser. In this paper we employ eight microsatellite loci to assess the population structure of 120 pacu sampled inside and outside the Pantanal of Mato Grosso. Our main objective was to test the null hypothesis of panmixia and to verify if there was a different structuring pattern between the Pantanal were there were no physical barriers to fish movement and the heavily impounded Paraná and Paranapanema rivers. All loci had moderate to high levels of polymorphism, the number of alleles varied from three to 18. The average observed heterozygosity varied from 0.068 to 0.911. After the Bonferroni correction three loci remained significant for deviations from Hardy-Weinberg, and for those the frequency of null alleles was estimated. F ST and R ST pairwise comparisons detected low divergence among sampling sites, and differentiation was significant only between Paranapanema and Cuiabá and Paranapanema and Taquari. No correlation between genetic distance and the natural logarithm of the geographic distance was detected. Results indicate that for conservation purposes and for restoration programs small genetic differences detected in the Cuiabá and Paranapanema rivers should be taken in consideration.

Abstract
A microsatellite locus from the Neotropical fish genus Prochilodus was isolated using PCR-based isolation of microsatellite arrays. Of 470 positive clones, 15 were sequenced, and 10 of them showed an (AATTT)(n) repeat. Primers were designed, and analysis of polymorphism revealed 11 alleles in three Prochilodus species. Fluorescence in situ hybridization analysis showed signals predominantly in the telomeric regions of several chromosomes. The description of this microsatellite may contribute to studies of the population structure of this fish group.
