Age composition of California landings of Bluefin tuna, Thunnus thynnus, 1963 through 1969
California landings of bluefin tuna, Thunnus thynnus, were sampled for age and size composition from 1963 through 1969. Scales were used to determine the age.Landings primarily consisted of 1- and 2-year old fish. The maximum age found was 6 years old. Strong year-classes of 1960 and 1961 combined to produce high catches in 1962 and 1963. Two year old fish appear to arrive in our fishery earlier than 1-year olds. (44pp.)
