dc.description.abstractBirthdate distributions of anchovy recruits caught during research surveys in June 1985 and June 1989 were compiled from weighted length frequency distributions, aged samples and length frequencies from commercial catches. Birthdates ranged from July to March with a peak in October for both year-classes. However, birthdate distribution for the 1989 year-class showed comparatively few fish spawning after October 1988. Also, the growth rate of recruits was slower in 1989 than in 1985. It is proposed that the very weak 1989 year-class of anchovy and the low spawning biomass subsequently observed were a result of poorer-than-average egg production and survival of prerecruits spawned after October 1988, and the slow rate of growth of juvenile anchovy recruited till June 1989.en_ZA
