  abstract = {{P}urse seine fishing on fish aggregating devices ({FAD}s) has expanded considerably during the last 15 yr in tropical tuna purse seine fisheries, and {FAD}s currently account for about 70 % of their reported tuna catches. {T}he scientific community has expressed concern over the consequences of this fishing practice in terms of yield per recruit and suspected detrimental effects on {FAD}-associated tunas. {T}o explore possible detrimental effects, we compared stomach fullness, fish plumpness, growth rate, and migration behaviour between free school and drifting {FAD}-associated tunas for skipjack tuna {K}atsuwonus pelamis and yellowfin tuna {T}hunnus albacares caught in the {A}tlantic and {I}ndian {O}ceans. {S}ignificant differences in fish plumpness and individual growth rates were found, suggesting that individuals associated with drifting {FAD}s were less healthy than those in free schools. {S}ince stomach fullness indicated that tunas associated with {FAD}s eat less than those in free schools, the difference in growth rate and condition could be the consequence of altered feeding patterns. {F}or each species, significant changes in migratory direction and displacement rates were observed in the presence of drifting {FAD}s. {T}hese findings support the hypothesis that {FAD}s act as a super-stimulus, misleading tunas to make inappropriate habitat selection. {H}owever, further studies are required to investigate the long-term effect of {FAD}s on the entire life cycle of tunas.},
