  abstract = {{T}he management of fish aggregating devices ({FAD}) creates heated debates in tuna fishery management organizations striving to reduce the number of deployed floating objects. {T}hrough several econometric models and a machine learning approach, we evaluate the consequences of three management scenarios on the catch and profit of the {F}rench purse-seine fleet operating in the {I}ndian {O}cean: (1) a half reduction in the number of authorized buoys per vessel, (2) a 72-day closure of {FAD} fishing with and (3) without re-allocation of effort on free schools. {T}he results show a significant decrease of fleet profits by 7%, 10% and 18% respectively. {W}e hypothesize an "economic trap" of {FAD} fishing caused by the far greater efficiency of this harvesting technique for larger vessels searching for economies of scale, and by the overfished status and catch limitation of yellowfin ({T}hunnus albacares) and bigeye ({T}hunnus obesus) tunas in the {I}ndian {O}cean. {T}he results are compared with other studies looking at the impact of {FAD} management measures in other oceans.},
