The blue catfish Ictalurusfurcatus (Lesueur 1840) is one of the Nearctic freshwater fish species of the Atlantic slope with a distribution extended to Neotropical localities as far southern as the Rio Usumacinta and the Rio Belize, Belize, where it was originally called Ameiurus meridionalis Gunther 1864 [= Ictalurus

In our study, two species (headwater catfish, Ictalurus

Three freshwater species (brown bullhead, Ictalurus

For the channel catfish, Ictalurus
punctatus, asymmetric sexual rates occurred, which favored the development of females when higher temperatures were applied during the critical period for sex determination (PATINO et al.
