(Cryobiology, 2014-12-01) [Artigo]
Groups of one hundred Brycon orbignyanus embryos at the stage of blastopore closure were subjected to different cooling protocols. Different combinations and concentrations of cryoprotectants were tested: sucrose, methanol, ...
Influences of Sex and Age on the Hematological Profile of the Jundia (Silver Catfish) Rhamdia quelen
(Journal Of Aquatic Animal Health, 2016-01-01) [Artigo]
In this study, sex and age influenced the hematological profiles of Jundia (Silver Catfish) Rhamdia quelen. Females showed lower levels of hemoglobin, young fish increased lymphocyte counts, and older fish increased ...
Growth, fatty acid composition, and reproductive parameters of diploid and triploid yellowtail tetra Astyanax altiparanae
(Aquaculture, 2017-03-20) [Editorial]
The aim of this study was to evaluate the growth, carcass yield, fatty acid composition, and reproductive parameters of diploid and triploid Astyanax altiparanae. Triploidization was induced by heat shock (40 degrees C for ...
