CalCOFI noted that if both the sardine fishery and competition from anchovies are affecting the sardine population--and if the objective was tobring back the sardine in the shortest possible time--there should be fish- ing on anchovies and a complete moratorium on sardine fishing. At the time of this proposal the total spawning biomass of anchovies in the Cali- fornia Current was estimated to be between and 2,25 million tons based on egg and larva data available through 1958. (The an- chovy population continued to increase since 1958, and in 1962 it reached a plateau rough- ly 2,5 to 4 times greater than the 1958 esti- mate. It remains there today.) In 1965 the Fish and Game Commission adopted regulations providing for an experi- mental fishery totake and use 75,000 tons of anchovies by a reduction process. Thus the anchovy reduction fishery began, and zones were established. A season was set and fish- ing was prohibited within three miles of the mainland shore. When the Commission authorized the an- chovy reduction fishery, the Department of Fish and Game initiated a project responsible for monitoring the fishery and conducting any biological studies on the anchovy necessary for resource management. Project objectives included determination of migratory habits, estimates of population size and mortality rates, catch locations, catch per unit of effort, number and pounds of anchovies landed, the age-composition of the catch, and other fishery statistics. Initial efforts were directed toward tagging and tag recovery, and fishery monitoring of the com-
