1. The influence of catch-and-release on mortality of Salminus brasiliensis (Cuvier, 1816)
Resumo O pesque e solte (PS) tem sido utilizado para auxiliar programas de manejo que buscam promover a conservação e recuperação de estoques de peixes esportivos, através da redução da mortalidade pela pesca. Entretanto, sem a manipulação adequada dos peixes, essa atividade pode causar injúrias nos indivíduos, causando mortalidade. Dessa maneira,

2. Conservation status and bio-ecology of Brycon orbignyanus (Characiformes: Bryconidae), an endemic fish species from the Paraná River basin (Brazil) threatened with extinction
RESUMO Brycon orbignyanus é uma espécie endêmica da bacia do rio da Prata, cujos estoques vêm apresentando redução relevante em todo o rio Paraná, e está classificada como espécie ameaçada. Este estudo avaliou aspectos da bio-ecologia da espécie, relacionados a essa ameaça, destacando sua distribuição, abundância, dieta e relação entre o rec

3. Actual status of fishing reserves of the Yesil River
ABSTRACT In this article, the study and prediction of the state of fish resources in the Yesil River was carried out to determine the boundary reference points of the reserve and management decisions in case they are exceeded, to ensure sustainable fisheries and preserve biological diversity. Ichthyological studies, retrospective analyses and rankings of the

4. The bony fishes (Teleostei) caught by industrial trawlers off the Brazilian North coast, with insights into its conservation
RESUMO A costa Norte do Brasil é um dos pesqueiros de camarão mais importantes do mundo, com uma área total de aproximadamente 223.000 km2. No entanto, dados disponíveis sobre a diversidade de peixes capturados pela frota industrial de arrasto de portas na região são limitados às espécies com valor comercial. Essa lacuna no conhecimento sobre a fauna

5. Checklist of marine demersal fishes captured by the pair trawl fisheries in Southern (RJ-SC) Brazil
Resumo: Nas costas tropicais e subtropicais, sobre as plataformas continentais, os recursos pesqueiros demersais são abundantes e considerados uma parcela importante do ambiente marinho. Os recursos pesqueiros demersais marinhos são capturados por diversas modalidades de pesca, muitas vezes de forma insustentável, o que vem provocando o esgotamento de seu

6. Length-based estimates of growth parameters and mortality rates of fish populations from a coastal zone in the Southeastern Brazil
ABSTRACT Small-scale fisheries in Brazil contribute to a significant share of total fish production, accessing a large variety of species. Life history parameters from these resources are important for their management and conservation, based on primary data. The objective of this article is to generate growth parameters and mortality rates of ten fish popul

7. Reproduction, feeding and migration patterns of Prochilodus nigricans (Characiformes: Prochilodontidae) in northeastern Ecuador
ABSTRACT The black prochilodus, Prochilodus nigricans, is an important food fish distributed throughout aquatic habitats of the Ecuadorian Amazon. We sampled gonad weight, body condition, and feeding of this species to address the question of whether changes in these biological parameters are related to hydrological variation and migration patterns. High fre

8. Larvae of migratory fish (Teleostei: Ostariophysi) in the lotic remnant of the Paraná River in Brazil
ABSTRACT Fish larvae and adults are morphologically distinct from each other and have different ecological requirements. Research on the dynamics of ichthyoplankton provides valuable information about the early stages of the life cycle of fish. This study analyzed the temporal and spatial distribution of the larval stages of three migratory species - Salminu

9. Genetic diversity and population structure of bocachico Prochilodus magdalenae (Pisces, Prochilodontidae) in the Magdalena River basin and its tributaries, Colombia
Prochilodus magdalenae is an endemic freshwater fish that occurs in the Magdalena, Sinú and Atrato hydrographic basins. It has an important economic role and is a food resource for the artisanal fishing communities. Its socioeconomic importance contrasts with the current status of its fisheries, where stocks are being depleted. Considering its importance an

10. Avaliação da estrutura genética do surubim, Pseudoplatystoma corruscans (Actinopterygii: Siluriformes) como subsídio para o repovoamento do submédio São Francisco
The São Francisco River is 2700 km long, draining areas of the States of Minas Gerais, Goias, Bahia, Pernambuco, Alagoas, and Sergipe, as well as part of the Federal District. Before the construction of Paulo Afonso Hydroeletric Power Plant, waterfalls of Paulo Afonso (north-eastern Brazil) and its respective lakes already constituted a natural obstacle to

11. Identification and phylogenetic inferences on stocks of sharks affected by the fishing industry off the Northern coast of Brazil
The ongoing decline in abundance and diversity of shark stocks, primarily due to uncontrolled fishery exploitation, is a worldwide problem. An additional problem for the development of conservation and management programmes is the identification of species diversity within a given area, given the morphological similarities among shark species, and the typica

12. Análise comparativa da variação genética entre os estoques cultivado e natural de Prochilodus argenteus : implicações para o repovoamento de rios
Introduction of hatchery fish in river has been the major using strategy for river fishery rehabilitation, working to attenuate river damage in short time. But there are effective risks about their efficiency and results, concerning the pool gene preservation and illness proliferation, beyond others ecologies and economics aspects. At São Francisco river, d
