Genetic Resources of Neotropical Fishes

Alexander Wagner Silva Hilsdorf is an Associate Professor in the Biotechnology Unit at the University of Mogi das Cruzes in Brazil. There he established the Laboratory of Aquatic Organism Genetics and Aquaculture, which uses molecular markers to investigate problems in fish breeding, fisheries monitoring, population genetics and conservation. Eric Hallerman is a Professor of Fish Conservation at Virginia Tech University in the United States. His research interests include population genetics of aquatic organisms, aquaculture, and biotechnology. He is a Fellow of the American Fisheries Society.
