2005: Rekord-Anlandungen an Nordseegarnelen (Crangon crangon L.) in Europa

Brown shrimp (C. crangon) landings are an important factor and ranked third in landings value of North Sea Fisheries. Landings data are gathered by country and kept separately. However, the Working Group on Crangon Fisheries and Life History (WGCRAN) of the International Council for the Exploration of the Sea (ICES) compiles statistical as well as biological data on brown shrimp. This group has met in Ijmuiden end of May 2006 and found new record landings in 2005 for all three major producers: Germany, The Netherlands and Denmark, summing up with The United Kingdom, Belgium and France to more than 38 000 tonnes of con-sumption shrimp, the highest landings ever recorded.

Os recursos de algas marinhas de importáncia económica na República popular de Moçambique com especial referéncia para Euchema (Florideae) em Cabo Delgado

Composition, abundance and environmental characteristics of the sea-weed resources of Mozambique were investigated along the whole Mozambican sea shore between May, 1979 and November, 1980. The limits of distribution of tropical algae were identified and located close to parallel 21 degree 00'S. Important concentrations of sea-weeds were found in the southern region, but only the Euchema resource in the coast of Cabo Delgado looked promising for commercial exploitation. Biological studies of Euchema were undertaken, the results of which permit the recommendation of a strategy for immediate harvesting which could yield 400-500 tons annually. Further proposals for the culture of sea-weeds are also included.

Avaliaçāo económica das medidas de gestāo da pescaria de camarāo do Banco de Sofala

The objective of this study is to recommend management measures for the industrial shallow-water shrimp fishery in Sofala Bank after estimating the economic affects considering different alternatives and assessing the level of exploitation of this fishery. The short-term economic analysis was based on the results of the total catch and average weight of the shrimp caught obtained by a simulation model in which different combinations of exploitation patterns and levels of fishing intensity were tasted. The variable parameters used were the mash size and the duration and period of the closed season, and all the remaining parameters were fixed. Economic and production data of the main industrial shrimp fishing companies for the period 1987-90 were also used.
