Book Description

Stomach contents of 924 striped marlin landed in the sport catches at Mazatlan, Sinaloa, and Buena Vista, Baja California, Sur, Mexico, and San Diego, California, and of 197 sailfish from Mazatlan and Buena Vista were examined. The striped marlin and sailfish fed primarily on pelagic fishes and cephalopods. By volume the major foods were squid (principally Dosidicus gigas) for striped marlin at Mazatlan and for striped marlin and sailfish at Buena Vista, northern anchovy for striped marlin at San Diego, and threadfin for sailfish at Mazatlan. Locally differences in food habits were pronounced, and some seasonal and yearly differences were found.
