Eighty–three artisanal fishing sites were documented from seasonal surveys of the Gulf of California coast of Baja California Sur conducted during El Nin˜o (1998) and La Nin˜a (1999) conditions. The direct targeting of elasmobranchs was observed at approximately half (48.2%) of these sites. Sharks numerically dominated sampled landings (71.3%, n 5 693), and exceeded those of batoids during all seasons. Among the primary species in observed landings were the scalloped hammerhead, Sphyrna lewini (15.2%, n 5148), Pacific angel shark, Squatina californica (11.6%, n 5 113), blue shark, Prionace glauca (11.4%, n 5 111), Pacific sharpnose shark, Rhizoprionodon longurio (11.3%, n 5 110), and pygmy devil ray, Mobula munkiana (8.6%, n 5 84).
