Status of Pacific mackerel spawning population, 1975
1975
Knaggs, Eric H. | Sunada, John S.
Three methods were used to determine the Pacific mackerelpopulation. The tag and recovery method estimated thepopulation at 620 short tons. The other two estimateswere based on regression techniques of partyboat catchesand these results yielded 2,921 tons and 1,385 tons,respectively. All three estimates were below the 10,000tons prescribed for a fishery and thus no harvest couldbe allowed. (14pp.)
