To assess the contribution of fish spawning aggregations to commercial marine fisheries in the Gulf of California, associations between the timing of spawning aggregations and monthly trends in commercial landings and revenue for aggregating reef fishes were investigated. Researchers then compared present (2000–2005) and past (1956–1961) landings of aggregating species groups. Five of eight of the most important commercial species peaked in mean monthly landings and revenue with the timing of their spawning aggregations. These results, cited over 30 times, suggested that targeted management of spawning aggregations is needed for certain species. Additionally, assessments of the interactions between fisheries and spawning aggregations were recommended, especially for gear types, in order to ensure sustainable fisheries of aggregating Gulf species.
