Evaluation of Larval Growth and Survival in Mexican Mojarra, Cichlasoma urophthalmus, and Bay Snook, Petenia splendida, Under Different Initial Stocking Densities

Journal of the World Aquaculture Society, 2009
Abstract Two experiments were conducted to evaluate the initial stocking density in larvae of Bay snook, Petenia splendida, and Mexican mojarra, Cichlasoma urophthalmus, using a recirculation system.
