Overexploitation of stocks in Guadeloupe's continental shelfhas led to consider other methods for fisheries in order to direct part of the fishery fleet towards unutilised or under utilised stocks. For that reason, since 1993, IRPM has started exploring unutilized stocks of Crustaceans. Faunistic inventories has been completed through fishing experiments using difIerent types of traps in waters from -200 m to -1500 m. In this way, a few species with potential for exploitation have been identified: namely lobsters Eunephrops cadenasi and few PlesioniTal and Heterocarpus shrimp species. Data including biological information on these stocks have been collected. The development of tishing techniques to improve yields and monitoring in order to ensure the preservation and renewal of the stocks are necessary. Yield estimates as well as analysis of capture composition have led us to recommend the use ofvery big traps (20 m3 using 38 mm mesh) or smaller traps "Saint-Martin type" (0.15 m3, mesh 50 mm).he possibility of developing this tishery has also been analysed.
