Population size and exploitation of giant squid (Dosidicus gigas D'Orbigny, 1835) in the Gulf of California, Mexico
The most important landing sites of the giant squid (Dosidicus gigas D´Orbigny, 1835) fishery in the Gulf of California, Mexico are Guaymas, in Sonora and Santa Rosalía, in Baja California Sur. An increase in the species biomass resulted in increased landings, ranging from 6, 200 tons in 1994 to 140...
