A total of 34 families, 63 genera and 96 species were registered. The otter trawl caught the highest number of species (48), followed by the plankton net (40), beach seine (37) and cast net (28). The most representative species for each gear, according to the biological value index, were: juveniles of Leuresthes sardina for beach seine, and juveniles and adults of Urolophus maculatus for the cast net and otter trawl. The families Gobiidae, Atherinidae, Gerreidae and Engraulidae were important at the larval stage and responsible for the minimum diversity values. Representatives of these families were also important at the juvenile stage. Thus, changes in diversity were influenced by the succession of dominant species. Species of Urolophidae and Gobiidae were found in different development stages, which indicates that they have high dependency on the system for their vital cycle. It is suggested that La Cruz lagoon is an important area for many fish species that make extensive use of it as a refuge, nourishment and/or reproduction zone. Para analizar la comunidad ictiológica de la laguna costera La Cruz, en el Golfo de California, se llevaron a cabo muestreos durante 1989-1991 con cuatro tipos de arte: red de plancton, red de playa, atarraya y red de arrastre de fondo. Se registraron un total de 34 familias, 63 géneros y 96 especies, aportando la red de fondo el mayor número de especies (48), seguida por la red de plancton (40), red de playa (37) y atarraya (28). Las especies más representativas para cada arte, según el índice de valor biológico, fueron: juveniles de Leuresthes sardina, capturados con red de playa, y juveniles y adultos de Urolophus maculatus, capturados con atarraya y red de fondo. Las familias Gobiidae, Atherinidae, Gerreidae y Engraulidae fueron importantes a nivel larval y responsables de los valores mínimos de diversidad. Ademas, representantes de estas familias destacaron en etapa juvenil. De esta forma, los cambios en la diversidad estuvieron influenciados por la sucesión de especies dominantes. Especies de las familias Urolophidae y Gobiidae se encontraron en diferentes estadios de desarrollo, lo que indica que tienen alta dependencia del sistema para su ciclo vital. Se sugiere que la laguna La Cruz es importante para muchas especies de peces que hacen uso extensivo de ella como zona de refugio, alimentación y/o reproducción.
