A 1980 F = 0.066 was considered to best represent the ages 6 and older stock status. partial recruitment on age 2 was adjusted to obtain a 1978 year-class size at age 1 of 2 billion fish while P.R. on ages 1, 3, 4, and 5 were adjusted to obtain year-class size at age 1 of approximately the smallest size observed. Various Y/R calculations and projections were made. These indicated that a 1982 catch of 115,000 mt would not adversely affect the stock status."--Abstract. |
