摘要：Along with consumption shrimp, brown shrimp fisheries also land some shrimp too small for human consumption which are sieved out on land and have to be degenerated ("crushed shrimp"). This share is recorded in German official s tatistics besides a third fraction called "indus trial shrimp". In view of the MSC certification processes, sustainable fishing and the fishermen's voluntary obligation to - in future - limit the shares of "crushed s hrimp", landings data from 2010 have been analysed. Depending on seasons the goal of less than 20% of "crushed shrimp" in German landings was not met in several months in 2010, especially in August, when more than 40% of the landings contained more than the proposed amount. The processing procedures aboard the ves sels are shortly discussed and the proposal is made to rather increase net selectivity than use wider sieves for the cooked fraction before landing. Cooking and processing small and later rejected shrimp is an uneconomic action. Reducing the share of "crushed shrimp" s erves the idea of sustainable use of shrimp s tocks as well as of sound economics
