New data (landings and survey) do not change the perception of the stock. The stock has suffered from declining recruitment since the early 1990ths. Results from surveys and catch rates show a clear decline, and indicates that the stock is close to a historically- low level. The year-classes have been record-low the last decade. The stock is therefor very poor. Taken in consideration the low production of golden redfish, this situation is likely to continue for many years.
ICES advises, as was done last year, that there should be no directed trawl fishery on Sebastes marinus in Subareas I and II in 2011. Area closures should be maintained and by-catch limits should be as low as possible until a significant increase in the spawning-stock biomass (and a subsequent increase in the number of juveniles) has been verified. .
Comments by IMR
The IMR supports the ICES advice. During the IMR autumn coastal waters survey from Varanger to Møre over the last years dense concentrations of Sebastes marinus have been observed. This is not new recruitment, but quantities who have been in the stock for a long periode. These isolated spots of dense concentration can easily lead to overestimatings and more uncertanty in the estimates. ICES has taken this in consideration in their estimates and advices. Based on data from catches and surveys the mature stock of golden redfish is estimated to ca. 30 000 tons.
