"A virtual population analysis was attempted using data from 1975 to 1981. There was a considerable difference in the total mortality rates calculated from commercial and research data and terminal F was difficult to estimate because of the shortness of the data series. Catch rates by the commercial fleet increased substantially in 1981 over 1980 and research vessel surveys indicated an increase in abundance over the period 1979-81. In spite of problems in arriving at a precise value for terminal F in 1981, the assessment indicated that the stock appears to be in good condition."
