    The reduction of discards will only be achieved, if more effective methods of catch selection will be developed and used. In principle, the unavoidable bycatch of commercial fish should be used for human consumption, independent of the requirements for minimum length and existing catch quotas. The amount of such bycatch should be charged to the total catch quota and preferably be used for processing of fish portions with skin (carcasses with skin), because this kind of processing results in higher yields and nutrional advantages compared to fillet processing. Unfortunately, nowadays, in the German fishery and fish trade this traditional form of supply is only of minor importance because of the predominance of fillets and fillet products. However, cooperation between fishing industry and fish trade and a good advertising of processed fish portions with skin could overcome this problem. In the pelagic fishery of herring, mackerel and other similar pelagic species the bycatch of small sized specimen of these species can be a problem. These small sized fish can principally be processed to traditional fish products, but the processing costs for them are much higher. The prospects for processing of the bycatch into minced fish meat, fish protein concentrate or fish protein hydrolysate are very poor under the existing regime in the German fishing industry. A further way for processing of the bycatch, which can not be used for human consumption, is the production of fish meal. However, only three German factory ships dispose of fish meal plants. Under the current economic conditions, i.e. because of limitted storage capacity, the German trawler and cutter fleet is not able to transport the bycatch for fish meal production ashore.
