Abstract
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.)
