Integrative approach detects natural hybridization of sympatric lambaris species and emergence of infertile hybrids [PDF]

Scientific Reports, 2019
AbstractDespite its relevance for ecology, evolution and conservation of species, natural hybridization and hybrids biology are still poorly studied in freshwater fish. Here, we tested the hypothesis that sympatric species Astyanax paranae and A. fasciatus are able to interbreed in the natural environment and presented evidence for the first record of ...

Performance of lambari-do-rabo-amarelo Astyanax bimaculatus (Linnaeus, 1758) fed diets based on adult black soldier fly meal: analysis of its effectiveness as a substitute for fish meal [PDF]

Brazilian Journal of Biology
This study evaluated the performance of the lambari-do-rabo-amarelo Astyanax bimaculatus fed diets containing BSF adult fly meal, replacing fishmeal. Two hundred juveniles were distributed in 20 tanks, with five levels of substitution (0%, 12.5%, 25%, 37.

Effect of food frequency on the growth of the lambari, astyanax bimaculatus (Characiformes, Characidae)

, 2022
The lambari, Astyanax bimaculatus, is one of the native species with zootechnical potential for aquaculture, and stands out with desirable characteristics for cultivation, therefore, studies regarding the ideal amount of food are necessary to improve the zootechnical performance of the species.

Reproductive performance of lambari ( Astyanax altiparanae ) in a seminatural system using different protocols

Aquaculture Research, 2020
We evaluated lambari (Astyanax altiparanae) reproductive performance by administration of gradually increasing doses of analogue of salmon gonadotropin-releasing hormone (sGnRHa). We performed two consecutive experiments applying six sGnRHa single doses in three replicates (ranging from 1 to 160 µg/kg) (Exp. 1) and three sGnRHa-fractioned doses in four

Atividades de lactato desidrogenase e malato desidrogenase de Astyanax bimaculatus (lambari) da bacia hidrográfica do rio Una como biomarcadoras de impacto ambiental [PDF]

Revista Ambiente & Água, 2015
Os peixes vivem todo o ciclo de vida na água e recebem a influência dos seus componentes físico-químicos e biológicos ao longo do tempo. As atividades de lactato desidrogenase (LDH) e malato desidrogenase (MDH) de organismos aquáticos podem ser alteradas

Desempenho reprodutivo de lambaris alimentados com grãos secos de destilaria

Boletim do Instituto de Pesca, 2017
Avaliou-se a influência dos ní­­veis de grãos secos de destilaria com solúveis (DDGS) no desempenho reprodutivo de lambaris. Foram elaboradas dietas contendo 0%, 10%, 20% e 30% de DDGS. Os peixes foram estocados durante 150 dias em 16 tanques com biofiltro, sistema individual de aquecimento e recirculação de água, na densidade de 0,3 peixe L-1.
