Ø Líneas de Investigación

El laboratorio fue establecido en el año 2001 y si bien estudia fundamentalmente la fisiologia de peces y la acuicultura del pejerrey, trabaja también, con un enfoque comparativo, en fisiología de la reproducción y diferenciación sexual en otros grupos de vertebrados. Las líneas de trabajo no sólo se relacionan con experimentos de laboratorio sino también en ecofisiología de la reproducción en peces y estresores ambientales naturales y de origen antrópico.
