Bycatch data was collected during two scientific observer programs conducted in the late 1990s and in the late 2000s. Over these two time periods, we compared the temporal trends in bycatch species composition, the probability of occurrence of functional groups per fishing set, the spatio-temporal species richness and the potential impact on several species listed in the red list of the International Union for Conservation of Nature (IUCN). The analyses were performed separately on the two main fishing modes of the fleet, i.e. sets on free-swimming school sets and on fish aggregating devices (FADs). Owing data quality constraints, we did not estimate bycatch rates. Ours results showed that the species composition of sharks caught on FADs decreased over time. The total species richness was higher for FAD sets than for free-swimming school sets (87 vs. 61 species respectively), such difference is common between fishing modes worldwide. specialized PECHE THONIERE PECHE MULTISPECIFIQUE SENNEUR DISPOSITIF DE CONCENTRATION DES POISSONS CAPTURE DIVERSITE SPECIFIQUE ESPECE MENACEE VARIATION PLURIANNUELLE BIODIVERSITE PRISE ACCESSOIRE ATLANTIQUE 040PECHE02 23 5 1157-1173 2014 0960-3115 https://www.documentation.ird.fr/hor/fdi:010061577 10.1007/s10531-014-0655-0 0960-3115 [F B010061577] https://www.documentation.ird.fr/hor/fdi:010061577 https://www.documentation.ird.fr/intranet/publi/depot/2014-04-08/010061577.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2014-04-08 2014-12-23 fdi:010061577 fre
