Panulirus argus) fishery in Cuba: current status, illegal fishing, and environmental variability
The Caribbean spiny lobster (
Spiny lobster, Panulirus argus (Latreille, 1804), is the most valuable fishery resource in Cuba. Despite strong management, the population shows signs of decline. The objectives of the present study were to complete a literature review and to evaluate spiny lobster status, including
illegal fishing. A statistical catch-at-age analysis, considering the addition of two environmental indices in the stock-recruitment relationship, was applied for two separate scenarios: one with official data (the "official model"), and a second including illegal fishing (the "total model").
Combined analysis of yield-per-recruit, spawning biomass-per-recruit, and stock-recruitment relationship was used to estimate equilibrium conditions at fixed levels of fishing mortality rate (F) and environmental conditions. Annual illegal catch represented 18.4% of total harvest. Recruitment
and stock size estimates in both models showed similar historical behavior with a decreasing trend and a recovery in the last 5 yrs. F estimates of the total model are higher than those of the official model. There were considerable differences in stock production for reference points
associated with environmental conditions, and the observed catch trajectory follows an average equilibrium curve. Incorporating illegal fishing led to lower maximum sustainable yield (MSY) and fishing mortality rate for the MSY (F
MSY) values than the official model. If not
taken into account, illegal activities can lead to the establishment of reference points that are higher than those that are sustainable for current populations. Despite the uncertainty associated with illegal fishing estimates, it is more precautionary to include them in stock assessments,
which can lead to management decisions that result in more sustainable fisheries.
