The objective of this study was to evaluate meat yield and centesimal composition the Amazonian fish species, A. ocellatus, P. castelnaeana, L. friderici, in dry flood seasonal cycles rivers. In each cycle (flood dry), a total 60 were collected, comprising 20 specimens following species: friderici. Were evaluated yield, cuts samples. Meat clean body skinless filet varied between species hydrolo...
There is limited information on the physiological consequences associated with exposure to xenoestrogens under field conditions. The objectives of this study were to determine the presence of estrogenic chemicals in the St. Lawrence River and their effects on male reproduction in the spottail shiner (Notropis hudsonius). Hepatic vitellogenin (VTG) mRNA levels in immature shiners indicate extens...
Nota sobre a identificação dos sexos do Apaiari, Astronotus ocellatus (Cuvier): (Pisces - Cichlidae)
The characterization of vitellogenin (VTG) receptors in ovarian membranes from vitellogenic female sea bass (Dicentrarchus labrax) is described. Incubation of membrane proteins with radiolabeled VTG (125I-VTG) after SDS-electrophoresis showed specific binding of 125I-VTG to a protein band of 100 kDa. Filter binding assays showed that binding of 125I-VTG to membrane receptors was saturable with ...
