[Reproduction, distribution and abundance of the fish Pseudupeneus grandisquamis (Perciformes: Mullidae), in the Gulf of Tehuantepec, Mexico].

As result of its biological and ecological strategies, Pseudupeneus grandisquamis is a dominant species in the demersal community of the Gulf of Tehuantepec, Mexico. Our main objective was to understand these strategies with respect to distribution, abundance and reproduction. We analyzed 5,175 individuals representing partial collections from five oceanographic expeditions between 1989 and 1990.
