Abstract:

The spiny lobster (Panulirus argus) is the most important fishery for 25 Caribbean countries, accounting to nearly 40,000 tonnes, valued in 286 Million USD. It provides jobs to 32,000 fishers. A biological and socio-economic assessment of the main ten countries and for the whole Caribbean lobster fisheries was made, based on catch data extracted from the FAO statistical records, population parameter values, costs and benefits of fishing, fleet effort/capacity, and numbers of fishers. Optimum harvesting strategies were evaluated providing the basis for recovery of regional stocks and for improvement of the consequent social and economic benefits. The analysis suggests that fishing pressure has been over exploiting some of these stocks in recent years. Despite these fisheries are still profitable, enhancement of recruitment and restoration of biomass in some cases is required. In those stocks that were found overexploited, reductions in fishing effort is advised, and the consequent economic effects and the reduction of fishers was evaluated. If the scenario that maximizes profits is adopted as management target, within a few years there would be a 26% increase in yield, 83% more benefits, and 14% more jobs respecting to the current condition, ensuring sustainable exploitation in the long term. It was found that nearly 25,000 tonnes of lobster heads constitute an almost unexploited resource, offering a significant and additional source of income.
