Abstract

State law requires that the population of Pacific sardines, Sardinops sagax caeruleus, must reach a minimum spawning biomass of 20,000 short tons before initiation of a fishery. Data from ichthyoplankton surveys, the anchovy live bait fishery, sea survey cruises, and the mackerel purse seine fishery are analyzed for evidence of an increase in population size. Presently, the spawning biomass of the northern stock of sardines remains far below 20,000 tons. (9pp.)
