Gulf weakfish, Gulf corvina
Gulf weakfish, Cynoscion othonopterus, is endemic to the northern Gulf of California and a vital component of commercial fisheries in the northern Gulf of California. A lack of information on life history parameters have prevented a comprehensive stock assessment.
This benthopelagic species inhabits coastal waters to depths of 30 m. Cynoscion juveniles are often found near river mouths but within this species' distribution, the one large river mouth available for juveniles is the Colorado River which has ceased to flow consistently since the 1960s (Gherard et al. 2013).
This species is threatened by overfishing within its very restricted range. Even though it is present in a Marine Protected Area (Biosphere Reserve), it is still fished seasonally during its spawning aggregation. Shrimp trawling activities also capture juveniles as by-catch. Declines in commercial landings have also been at least partially attributed to reduced river flow (Chao et al. 2010).
Within FishSource, the term "fishery" is used to indicate each unique combination of a flag country with a fishing gear, operating within a particular management unit, upon a resource. That resource may have a known biological stock structure and/or may be assessed at another level for practical or jurisdictional reasons. A fishery is the finest scale of resolution captured in FishSource profiles, as it is generally the scale at which sustainability can most fairly and practically be evaluated.
