Abstract
    This paper presents the design and the parameters of a bio-economic model of sequential artisanal and industrial fisheries for tropical shrimp. It consists of a biological part based on a yield per recruit (Y/R) Thompson and Bell model and an economic part based on a simple input-output model. The model and the computer programme have been used to analyse the shrimp fisheries of Suriname. The simulation results presented and the policy advice given have therefore to be interpreted with caution and have to be reviewed when more detailed and reliable data become available on Suriname's shrimp fisheries. Two main conclusions emerge from the analysis, namely that (i) a strong expansion of artisanal fisheries for juvenile penaeid shrimp in coastal swamps is likely to lead to a reduction in the shrimp catch and gross revenues of the offshore trawler fleet and that (ii) the offshore trawler fleet is heavily over-capitalized.
