Resumen del producto

The northwest region of Mexico supplies the most abundant share of fish products in the country. Most of the region is a temperate-tropical transitional area. Coastal wind-induced upwelling occurs seasonally along the west coasts of both the Baja California Peninsula and the continent. Permanent topographical upwelling takes place in two large areas. Fisheries are mostly industrial, Sonora being the largest producer in Mexico, followed in the region by Sinaloa, Baja California Sur and Baja California. The most abundant fishery is that of small pelagic fishes, while the jumbo squid fishery follows some years. The most valuable fishery in the country is that of the penaeid shrimp in the Gulf, together with a rapidly expanding aquacultural component. Abalone and lobster fisheries are the main economic activity for some 10,000 inhabitants in 30 settlements at the west coast of the Peninsula. Other small scale fisheries include blue crabs, sea snails, clams and the large number of scale fish and sharks, skates and rays fisheries. These create the largest number of jobs and produce the most of fresh fish products for the local and regional markets. It has been claimed that coastal food webs have been “fished down” in the Gulf; however, other studies based on widely accepted methodology have shown opposite results, concluding that there is no sign of fishing down.
