N2 - The seasons and spawning areas for sailfish Istiophorus platypterus along the Pacific coast of Mexico are described based on the histological analysis of ovarian samples, eye orbit fork length, and sex ratios for 867 sailfish. Sampling was conducted during 1989 to 1991 from sport fishing tournaments at the tourist ports of Cabo San Lucas, La Paz, Mazatlán, Puerto Vallarta, Barra de Navidad and Manzanillo. Five maturity stages are characterized and used to establish three degrees of reproductive activity that are correlated with the gonad index values. Sailfish reproduce during summer and fall, and sex ratios and percentages of mature females vary geographically.
