There are over 200 fish stocks for which the EC Fisheries Council sets total allowable catches (TACs). Only one of those stocks, Clyde herring, is exclusively within the United Kingdom's (UK) fisheries limits (this is unchanged by the cessation of the sovereignty of Rockall). The others are in other sea areas as well as the UK's limits. For these stocks, no separate part of the total allowable catch is related exclusively to the UK waters involved. Therefore, it is not possible to provide the information requested.
