  abstract = {{H}uman-induced habitat modifications can severely impact the biology and behavior of wild species. {D}rifting fish aggregating devices ({DFAD}s), used by industrial purse-seine tropical tuna fisheries, significantly increased the number of floating objects found in the open ocean, with which tropical tuna associate. {T}his habitat change has raised concerns over the risk of modifying the behavior and altering the biology of tuna and other associated species (the so-called ecological trap hypothesis). {R}elying on a time-series from 1987-2019 of more than 25000 length-weight samples collected in the western {I}ndian {O}cean, we reject the hypothesis that the body condition ({L}e {C}ren's relative condition factor, {K}n) of yellowfin tuna {T}hunnus albacares decreased concurrently with the increased number of {DFAD}s. {T}his result suggests the absence of negative long-term impacts of {DFAD}s on the condition of tuna. {A}s other factors may have counteracted possible negative effects of {DFAD}s, we recommend long-term monitoring of the habitat along with biological and behavioral parameters of tunas to detect any critical change.},
