| Abstract |
The brown shrimp is found in appreciable numbers along the coasts of the southern North Sea and forms an important coastal fishery. The fishery is carried out by small fishing boats (motors of 35 to 120 h.p.). Most of them use the "beam-trawl" and some of them “ottertrawl". The minimum width of the meshes of the shrimp trawl varies between 16 and 20 mm. In France, Belgium and the United Kingdom all shrimps landed are used for human consumption, whilst in the Netherlands and in the German Federal Republic, 60 to 80% of the landings are taken up by fish-meal factories. The annual catches are subject to marked seasonal fluctuations and in all countries concerned a reduction of the catches in relation to the fishin8 effort has been observed during the last few years. The majority of the fishermen consider that the damage inflicted by the fishery itself causes the scarcity of shrimps. This is due to the increased intensity of the fishery and to the recent modernisation of the fishing boats and the fishing gear. To remedy this state of affairs, several protective measures could be taken : a) limitation of the fishing fleets and of the engine power; b) restriction of the fishery on immature shrimps; c) permanent or temporary closure of certain zones to the fishery; d) regulation of the size of the meshes; e) mechanical sifting on board the fishing boats so as to allow the immature shrimps to be returned immediately to the sea. |
