Marine fish culture in Mexico is still in a developing stage because there are no culture technologies yet. Two critical stages in marine fish culture are reproduction and nutrition during larval stage.

Research emphasis has been on reproductive physiology and larval culture of three marine fish: Leopard grouper (Mycteroperca rosacea), Yellow snapper (Lutjanus argentiventris), and North Pacific yellowtail (Seriola lalandi). Besides, works have been performed on optimizing Leopard grouper juveniles for experimental fattening.

With respect to pathology topics, we have studied the effect of the bacteria Aeromonas hydrophila on two initial life periods of Leopard grouper (embryo and juvenile).
