HARVEST CONTROLE RULE FOR THE ISLAND SCALLOP WITHIN THE NEW APPROACH TO THE BARENTS SEA STOCK ASSESSMENT
Abstract
The paper presents brief results of the Barents Sea Iceland scallop stock status estimation and fishery management. At present, the Iceland scallop Chlamys islandica stocks in the Barents Sea Cape Svyatoy Nos settlement are in the depressive state. The long-term dynamics of the commercial stock shows approximately five time reduction during the fishery exploitation period. A stochastic version of the Shaefer production model was used for the integrated assessment of the stock status, the calculation of TAC and reference points and the forecast of the biomass dynamics. The reference point by the commercial stock biomass (Btr) of the Iceland scallop from the Cape Svyatoy Nos settlement equaled to 224 thousand t. A median value of the target reference point by exploitation (Ftr) was estimated at 0.002. It can be expected that if the dragging has been temporarily stopped and there is no strong recruitment of the Iceland scallop stock in the Barents Sea, it will, probably, take the Iceland scallop 15-20 years, at least, to recover to the biological safe level.
