During the 1980s about 60 percent of total lobster landings came from the Pedro Bank but that declined to 20 percent in 1996-1997. The contribution of lobsters landed in Jamaica that come from the island shelf and the banks have not been recently quantified (Kelly, 2002). According to Munro (1983) the lobster populations in Jamaica have changed considerably. Kelly (2002) noted that fishing effort had increased significantly in the preceding recent years and that the level of fishing mortality at that time appeared to be greater than the optimum recommended for the fishery in 2002. FAO (1993) declared that from a biological perspective, fishing mortality should be reduced to minimize the risk of over-exploitation.

An update of the previous year’s assessment was carried out on the industrial lobster fishery of the Pedro Bank.
Data

The annual total catches that were used in the assessment included data from the industrial fishery from Pedro Bank. Total catches of lobsters from the industrial fleet were estimated to be equal to total exports. For the purposes of this assessment it is assumed that the industrial fleet catch is a constant proportion of the total catch. This assumption needs to be further verified. Export data were available from 1979 – 2007 with three years missing (1982, 1983, 1990). CPUE was obtained for lobster pot fishing operations on Pedro Bank for 10 years (CARIFIS database). The major challenges posed by the data were the gaps in the data series, and uncertainty in the CPUE index as a good index of abundance.
Results

The results, due to limitations of the available data, were still not conclusive, but provided some indications of the status of the fishery. The model suggested the stock is not overfished and current catches are not resulting in overfishing. With the inclusion of an additional three years data there is still no evidence that the stock is overfished. Both the previous and updated assessment revealed that the recommended MSY from the Pedro Bank was at a median of 200mt. Data from the industrial fishery revealed that since 2004 the catch has been decreasing from 450 mt to 111.5 mt as seen in 2007. With lower catches, the model now predicts that the stock is not being overfished (F < FMSY) and is not overfished (B > BBMSY). It should be noted that the production model does not fit the data well. This is because the catch rate series does not appear to be informative. Consequently, the model outputs are highly dependent on what is being assumed for the priors. Nonetheless, the model is the only one currently available and provides some guidance on appropriate levels of harvest.
