  abstract = {{T}ime-area regulations have been introduced to manage stocks of tropical tuna, given the increased use of drifting fish aggregation devices ({FAD}s). {H}owever, the consequences in terms of changes in fishing strategies and effort reallocation may not always be as expected. {F}or instance, in the eastern {P}acific {O}cean, previous studies have highlighted that the increase use of {FAD}-fishing following the demand for tuna caught without dolphin mortality has raised concerns about the bycatch and the capture of juvenile tuna. {I}n the tropical eastern {A}tlantic and western {I}ndian {O}ceans, this study aimed to (1) assess, using before-after analysis, the consequences of previous time-area regulations on {FAD} sets on the fishing effort allocated to megafauna associated sets, and (2) evaluate through {M}onte {C}arlo simulations the potential effect of new regulations banning whale or/and whale shark associated sets. {F}irstly, we showed that previous time-area regulations, which were mainly implemented during seasons with few whale and whale shark associated sets, generally had thus little effect on the number of megafauna associated sets. {S}econdly, some simulations, particularly when both whale and whale shark associated sets were banned, predicted consequences of changes in fishing strategy. {I}ndeed, these types of ban could lead to an increase in the number of {FAD} and free school sets but no change in the tuna catch, as well as a slight decrease in bycatch. {T}hese results indicate that an ecosystem approach to fisheries, by taking into account megafauna associated sets and bycatch, should thus be adopted when implementing management or conservation measures.},
