The southern California Jack Mackerel fishery, and the age and length composition of the catch for the 1972-73 through 1983-84 seasons

Abstract

Jack mackerel landings in southern California during the 1972-73 to 1983-84 seasons indicate successful year classes in 1974, 1976, 1978, and 1980, each contributing over 150 million fish to the fishery. These alternated with weak year classes in 1973, 1975, 1977, 1979, and 1981, each contributing less than 60 million fish. A majority of the fish were caught as one- and two-year-olds and were less than 300 mm in length. (45pp.)
