    Abstract

    State law requires that the population of Pacific sardines, Sardinops sajax caeruleus, must reach a minimum spawning biomass of 20,000 short tons before initiation of a fishery. Data from ichthyoplankton surveys, sea survey cruises, the anchovy bait fishery, and jack mackerel purse seine fishery are analyzed for evidence of an increase in population size. Presently, the spawning biomass of the northern stock of sardines is far below the minimum requirement. (8pp.)
