Assessment of the North-East Arctic and North Sea Stocks of Saithe Taking Into Account Migration
Original version
This report is not to be quoted without prior consultation with the General Secretary.Abstract
Tagging experiments have shown that there is a substantial migration of young saithe from the Norwegian coast north of 62°N to the North Sea. Assessments of the North-East Arctic and North Sea Stocks of saithe were made assuming that all 1-4 year old saithe caught between 62° and 64°N would have recruited to the North Sea stock. The new assessments give a decrease in the level of recruitment to the North-East Arctic stock and an increase to the North Sea stock. he exploitation of the NorthEast Arctic stock is close to F max , whereas the North Sea stock is subject to considerable growth overfishing. Reduction in the exploitation of young saithe between 62° and 64°N will benefit chiefly the North Sea stock.
