Técnicas de fertilização de água de biofloco para Astyanax altiparanae

OBSERVATÓRIO DE LA ECONOMÍA LATINOAMERICANA
A aquicultura contribui essencialmente para a segurança alimentar, e está em constante crescimento. No entanto, tem sido necessário tornar a aquicultura e piscicultura mais sustentáveis, priorizando sistemas de produção com baixa demanda e descarte hídrico. Nesse sentido, surge o BFT como uma alternativa.

Growth performance of Astyanax altiparanae fed with plant and/or animal lipid sources

Revista de Ciencias Agrícolas, 2019
The lambari, Astyanax altiparanae, exhibits a great potential for aquaculture due to its omnivory, rapid growth and ease captive production. Despite of fish lipid metabolism being directly related to the dietary lipid consumed, which may lead to changes ...

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

Food resource used by small-sized fish in macrophyte patches in ponds of the upper Paraná river floodplain = Uso do alimento por peixes de pequeno porte associados às macrófitas aquáticas em lagoas da planície de inundação do alto rio Paraná

Acta Scientiarum: Biological Sciences, 2009
This study analyzed the diet of seven small-sized fish species(Characidae) and assessed their use of food resources. The species were collected in 2001 from nine ponds with aquatic macrophytes in the Paraná river floodplain, Brazil. Astyanax altiparanae,
