Sufficient offspring for brown shrimp?

Background and Objective

Brown shrimp fishery is from the economic point of view the most important fishery in Germany. It gives direct as well as indirect employment for a number of people along the coast and has an impact on regional tourism. Monitoring brown shrimp stocks and the accompanying fauna from chartered and research vessels and the landings serves for the understanding of the ecosystem and population dynamics of brown shrimp in view of a sustainable and ecologically sound fishery in the region. Prediction models for landings and life cycle are intended to improve stabilising mechanisms for the fishery and processing. Results are contrarily to normal fisheries research activities not used by the CFP of the EU but available directly to local authorities, producers organisations and ICES, which established a working group (WGCRAN) to investigate basic biological information and modelling of brown shrimp on an international, European-wide level.
