The European Community fishing quotas are determined at the December meeting of the Council of Ministers held in Brussels.
These quotas are published in an annual Total Allowable Catch Regulation; this legislation fixes the fishing opportunities for certain fish stocks and groups of fish stocks, applicable in Union waters and, to Union vessels, in certain non-Union waters.
