Résumé : Rumpons, (fads) were widely deployed in Indonesia in the eighties. In the Halmahera area, rumpon increased cpue by 41% , landings of fish per ton of live bait increased by 24%, the consumption of diesel oil for tuna catches reduced by 46%, and profits increased from Rp 10 to 60 million by boat per year1. Tuna aggregation around rumpon increased catchability by more than 40% compared to free swimming tuna. The Halmahera skipjack fishery was assessed by combining catch and effort data from rumpon and pre-rumpon areas of the fishery, and showed that controlled effort could increase landings of approximately 15,000 t per year. Tagging data show that the Halmahera skipjack fishery is probably supported by a local unit stock. Philippine rumpons (payaos) were fished with small mesh purse seine and ring nets fishing small sized tunas 12-35 cm fl (40-50% of landings) and caused recruitment overfishing. Indonesian rumpons were fished with pole-and-line causing neither recruitment nor growth overfishing.
