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.
