520 |a"The TAC of 18,000 MT was not achieved in 1980, with only 7500 MT being landed due to a reduction in fishing effort. Using a multiplicative model, a new effort standard is introduced. An analytical assessment was carried out and a series of regressions run to determine the best terminal F. The results from regressions proved inconclusive, however, a comparison of the catch ratio between 1973 and 1979-80 with the biomass ratio for the same years from cohort suggested a terminal F of 0.075. Fishing at F0.1 of 0.15 in 1982 suggested a TAC of 18,000 MT. Again in 1980 there is good evidence of a number of relatively strong year-classes that will be available to the fishery in the near future"--Abstract.
