Maturation and growth of jack mackerel, Trachurus symmetricus
Biological knowledge of jack mackerel is not extensive,and as yet no information on maturity or growth ratehas been documented. Analysis of fish caught in theSouthern California Bight indicates a spawning seasonfrom March through October. By the end of their firstyear, most females (70%) are capable of spawning, andthe percentage increases with age.Weight-length curves were calculated for a 2 monthperiod (July and August), and for the entire year. Avon Bertalanffy growth curve was determined fromJuly-August data to represent size of each age groupnear the designated August 1 birthdate. (328pp.)
