ICES-Arbeitsgruppentreffen zum "Lebenszyklus und Fischerei von Nordseegarnelen" (WGCRAN)

Two years after their last meeting, scientists from North Sea neighbouring countries working on aspects of brown shrimp biology and fisheries gathered in Oostende, Belgium, to exchange information and results of their research. The group was established ten years ago by the International Council of the Exploration of the Sea (ICES)during the Warnemünde Annual Science Conference. Data on brown shrimp landings, fishing effort and resulting landings per unit effort were compiled. For the first time a computer model was demonstrated simulating the life cycle of C. crangon on basis of experimental and field data available. It will provide a means for testing different possible scenarios and their effect on the brown shrimp stocks. Catch predictions are not possible by this, as no stock assessments can yet be achieved for brown shrimp, and a number of topics have to be addressed by further research programmes. However, an approach of estimating the level of landings on basis of preceding climatological and hydrographical data seemed promising. Furthermore selectivity experiments and electric gear types were reported giving reason to assume, that progress is possible in the further reduction of bycatches. The assembling of already existing data in various countries and their evaluation was recommended besides the pursuing of the mentioned fields of research and proper reporting of EU log book data by all countries.
