Management of Sea Herring Fisheries in the Northwest Atlantic
Regulatory measures for herring set by the International Commission for the Northwest Atlantic Fisheries (ICNAF) represent an important milestone in international fishery regulation because for the first time, they provide for national quotas in addition to a total catch limitation.The first regulat...

Regulatory measures for herring set by the International Commission for the Northwest Atlantic Fisheries (ICNAF) represent an important milestone in international fishery regulation because for the first time, they provide for national quotas in addition to a total catch limitation.The first regulatory measures were proposed in January 1972 to be effective that same year. In January 1973, the effects of the 1972 catch on the stock were evaluated, national quotas for 1973 were proposed, and conditional allowable catches for 1974 were proposed depending on stock size at the end of 1973.
