N2 - 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 140,000 tons in 1996. The development of a management strategy for this fishery based on the proportional escapement has been suggested. This necessitates the estimation of the population size when the fishing season begins in order to determine the amount of fishing effort. Weekly catch and effort data were reported from October 1995 to March 1996 for three fleets operating in the Gulf of California. The population size estimated using a maximum likelihood model was 82,000 tons with a proportional escapement of 66%.
