| Tiger shrimp aquaculture is re-emerging in West Bengal after crashing in 1994. Shrimp aquaculture in West Bengal depends on fry collected from inshore areas, thus reducing recruitment to the capture fishery. In Chapter 1, I developed a simulation model to analyse the impacts of four development scenarios on the aquaculture and capture fishing industries. Results indicate that although the current harvest rates are sustainable, restricting the number of fry collectors would enhance yield in both sectors. Increasing the number of fry collectors is not sustainable.; While some researchers have found positive correlations between mangrove forest area and fishery yields, others argue that the importance of the shrimp-mangrove linkage has been overstated. Some researchers suggest mechanisms underlying the shrimp-mangrove linkage. In Chapter 2, I use simulation modelling to evaluate two of the mechanisms proposed to explain the link between mangrove forest area and shrimp fisheries.; Keywords.
