Sea cucumber fishery is a very important fishery in many tropical island countries and has been playing a significant role in poverty reduction in developing countries for many years. However, overfishing has become prominent due to growing market, especially in countries with weak management capacity leading to local stock depletion. In order to find sustainable management option for this fragile fishery, we studied one of the best managed sea cucumber fishery in Seychelles. Using their detailed spatially explicit fishery log, vessel monitoring system log, market export log, and in situ survey data, we examined the habitat preference of the species, estimated their stock size, studied the fishery trend, and created hierarchical, spatially explicit surplus production model to be used in management strategy evaluation.
