One of the most important fisheries resources of Mexico is the snook group, considered among the most precious organisms for coastal and inland fishermen. Fishing pressure on this resource has resulted in declining catch rates, especially for large organisms (mainly composed of adult females). The development of aquaculture techniques for native species can help reduce the pressure on wild populations, and can also provide a reliable supply for the development and implementation of programs for restocking the over exploited stocks. Dr. Hillary Egna worked with OSU F&W alums Dr. Wilfrido Contreras-Sanchez of Universidad Juárez Autónoma de Tabasco, Villahermosa and Dr. Reynaldo Patino of Texas Tech University to develop successful methodologies for obtaining snook fry from captive broodstock.
