Whereas it is necessary to repair the prejudice suffered by a Member State which has not exhausted its quota , its allocation of part of a stock or group of stocks when the fishery has been closed following the exhaustion of a TAC; whereas to this end a system of compensation should be provided for.. This sentence is hard to understand. A simpler version with equivalent meaning is the following:
In the event that fishing is stopped because the TAC has been exhausted , provision should be made for Member States which have not used up their quota or the share of a stock or group of stocks allotted to them to receive compensation . A compensation system must be provided for this purpose .
