An assessment of redfish in Subarea 2 + Division 3K / by C.A. Gavaris and D.B. Atkinson. : Fs70-8/82-31E-PDF

"The status of the redfish stock in Subarea 2 and Div. 3K was evaluated using standardized catch rate data, commercial length and age frequencies and research vessel surveys. The catch rate series showed a moderate increase from 1979 to 1981, the data for both 1980 and 1981 being preliminary. The 1981 research vessel survey showed an abundance of 25-29 cm fish which would correspond to the early 1970's year-classes. These year-classes have been in evidence in previous surveys but not as strongly as in 1981. Commercial length frequencies also showed an abundance of 25-29 cm fish. The stock may be increasing, however the data available at present do not permit a firm quantative assessment of the increase. Catches from 1970-81 averaged 24,250 t well below the present TAC of 35,000 t."
