San Ignacio Lagoon, located in northwestern Baja California
Sur, is an important site for commercial fisheries; however, studies
specifically addressing the taxonomic diversity of its fish communities remain
scarce. To fill this gap, we assessed the diversity of fish associated with soft-bottom
habitats across 11 sites from spring 1998 to winter 1999, using alpha, beta,
gamma, and taxonomic distinctness indices (Δ* and Δ+). A total of 1,361
specimens representing 44 species and 35 genera were recorded. Seasonal
analysis revealed the highest alpha diversity in summer, while beta diversity
peaked in spring. Gamma diversity was greatest in spring and summer, with 27
species each. Spatial analysis showed significant differences in Δ+, whereas
temporal variation was not significant. These findings highlight the ecological
importance of San Ignacio Lagoon and provide baseline data for future
monitoring and conservation.
