Description of amino acid and fatty acid content during initial development of Lophiosilurus alexandri (Siluriformes: Pseudopimelodidae), a carnivorous freshwater catfish

Neotrop. ichthyol; 16 (2), 2018
Samples of eggs, newly hatched larvae (NHL), and larvae at the end of the lecithotrophic period (eight days after hatching) (LPL) of Lophiosilurus alexandri were collected to determine the amino acid and fatty acid profiles. Crude protein did not change throughout initial development and the concentratio...

Management proposal based on the timing of oral incubation of eggs and juveniles in the sentinel species Genidens genidens (Siluriformes: Ariidae) in a tropical estuary

Neotrop. ichthyol; 16 (4), 2018
Ariids such as Genidens genidens are particularly susceptible to overfishing because of their complex reproductive mechanisms, which result in slow replenishment of stocks. In this study, we obtained data about the reproductive ecology of the catfish G. genidens in the Guanabara Bay estuary, Rio de Janei...

Toxicidade aguda ao sal comum e larvicultura intensiva do jundiá Rhamdia quelen em água salobra

A tolerância de peixes de água doce à salinidade e os níveis adequados de náuplios de Artemia na alimentação durante a larvicultura são de extrema importância para a padronização dos manejos em ambientes de criação intensiva. Dessa forma, o objetivo do trabalho foi estimar a salinidade letal...
