The purse seiners of the Java Sea use light and Fish Aggregating Devices (FAD) to catch the fish. The use of such fishing devices invites questions on the relation which can exist between fish and the fishing vessels. The use of acoustic cruises on fishing grounds, linked with the location of fishing vessels, can give us a first knowledge of such a relation. In the Java Sea, it seems that the fishermen are able to detect fish concentrations, even if they are close to the bottom. They increase a natural phenomenon which is the rising of this fish population at night. With the lights, they seem to alter the distribution of the fish within these concentrations, in order to aggregate it around the vessels and to catch it. (Résumé d'auteur)
