Abstract

Analyses of catch data on oil sardine from 1966-67 through 1976-77 indicated
that the fluctuations in the fishery were closely related to the strength of
different age groups. The fishery appeared to be good when the 0 and 1 year
groups were equally and continually represented in the catches. The estimated
average rate of instantaneous rate of mortality was 1-87.
