Abstract

Determination of sex ratio of the oil sardine during the period of 7 years, 196C—67,
showed that there is not much difference in the ratio of the two sexes during the fishing
seasons and the apparent variation which is seen from month to month is probably due
to inadequacy in sampling. Disparity in sex ratio in one-year class in most years and
equality of both the sexes among the two-year old fishes have been recorded. The
occurrence of oil sardine at different stages of maturity has been determined. Active
spawning seems to occur from June to September.
