  abstract = {{G}iven the increasingly extensive use of drifting fish aggregation devices ({FAD}s) by the purse-seine fisheries targeting tropical tunas, fishing effort restrictions have been introduced to manage tropical tuna stocks. {H}owever, these measures are focused on the protection of juvenile tunas and do not take account of the potential impact on bycatch or associated megafauna (whales and whale sharks). {A}n iterative "fishing-day" {M}onte {C}arlo simulation model was developed to investigate the consequences on tropical tunas and bycatch of introducing extensive area 6-month moratoria on {FAD} activities. {T}he model allowed for variability in a range of plausible values of the parameters characterizing the fishing operations conducted by {E}uropean purse-seiners in the eastern tropical {A}tlantic and western {I}ndian {O}ceans for the period 2005-2014. {M}onte {C}arlo simulations, using probabilities based on these fishery data, were carried out for the {F}rench and {S}panish fishing fleets separately to account for differences in fishing strategies. {T}he models predicted a decrease in {FAD} sets and an increase in free school sets. {A}s a consequence, the catch of small tuna (<10 kg) decreased while the catch of large tuna (>= 10 kg) increased, leading to an overall increase in tuna catch of 100-200 tons/year/vessel in the {A}tlantic {O}cean, and a decrease of 400-1500 tons/year/vessel in the {I}ndian {O}cean. {T}he bycatch decreased in the {I}ndian {O}cean, while in the {A}tlantic {O}cean billfishes, turtles and chondrichthyans bycatch increased slightly and other bony fishes decreased. {B}ecause fishing practices were modified, whale and whale shark associated sets increased slightly in the {I}ndian {O}cean.},
