Abstract

Dosidicus gigas, the only species in the genus Dosidicus, is commonly known as the jumbo squid, jumbo flying squid (FAO, see Roper et al., 1984), or Humboldt squid. It is the largest ommastrephid squid and is endemic to the Eastern Pacific, ranging from northern California to southern Chile and to 140oW at the equator (Nesis, 1983; Nigmatullin, et al., 2001). During the last two decades it has become an extremely important fisheries resource in the Gulf of California (Ehrhardt et al., 1983; Morales-Bojórquez et al., 2001), around the Costa Rica Dome (Ichii et al., 2002) and off Peru (Taipe et al., 2001). It is also an active predator that undoubtedly has an important impact on local ecology in areas where it is abundant (Ehrhardt et al., 1983; Nesis, 1983; Nigmatullin et al., 2001; Markaida and Sosa-Nishizaki, 2003).
