El laboratorio fue establecido en el año 2001. Si bien estudiamos fundamentalmente la fisiología de peces y la acuicultura del pejerrey, trabajamos también, con un enfoque comparativo, en fisiología de la reproducción y diferenciación sexual en otros grupos de vertebrados.

Nuestro trabajo no sólo se realiza en laboratorio sino también con un enfoque ecofisiológico estudiando reproducción en peces en su medio natural y el efecto de estresores ambientales de origen natural y antrópico.
