Knaggs, Eric H. and Sunada, John S. (1975) Status of Pacific mackerel spawning population, 1975. Long Beach, CA, California Department of Fish and Game, Marine Resources Region, (Marine Resources Administrative Report, 75-5)
Abstract
Three methods were used to determine the Pacific mackerel population. The tag and recovery method estimated the population at 620 short tons. The other two estimates were based on regression techniques of partyboat catches and these results yielded 2,921 tons and 1,385 tons, respectively. All three estimates were below the 10,000 tons prescribed for a fishery and thus no harvest could be allowed. (14pp.)
