Última Technologie des dispositifs de concentration de poissons et techniques de pêche aux gros pélagiques. Compte rendu d'essais effectués pendant l'été austral 1989-90 ArchiMer Biais, Gerard; Taquet, Marc. Fish aggreagating devices (FAD), "semi-heavy" models, have been anchored all around La Réunion Island since 1988. For maximising profits derived from them, "light" FAD less expensive have been designed and locally unused fishing gears were tried. The use of this latter appears to be limited in local context, but in contrast the use of "light" FADS seems an interesting way. Their design calculus are given.

The purse-seiners of the Java Sea use light and fish aggregating devices (FAD) to concentrate and catch small pelagic fish (Decapterus sp., Amblygaster sirm, Sardinella gibbosa). This sets a question about the interaction between fish and fishing vessels. Relevant estimates of fishing mortality and fishing effort require an understanding of this interaction. To gain information on this relationship, acoustic surveys were performed on the fishing grounds and the present paper analyses these data. Using acoustic surveys, the fish density was measured and the number of schools was counted per sea surface unit. The fishing vessels were located by radar. Acoustic data were stratified into two groups, one where fishing vessels were present and the other where...
