  abstract = {{M}anaging populations of wild harvested species requires the ability to regularly provide accurate abundance assessments. {F}or most marine species, changes in abundance can only be monitored indirectly, using methods reliant on harvest-based indices, with significant inherent limitations surrounding the estimation and standardization of harvest effort. {T}ropical tunas are some of the most exploited marine species in the world and are among several species in critical need of alternative methods for estimating abundance. {A}ddressing this concern, we developed the {A}ssociative {B}ehaviour-{B}ased abundance {I}ndex ({ABBI}), designed to provide direct abundance estimates for animals, which exhibit an associative behaviour with aggregation sites. {I}ts implementation in the western {I}ndian {O}cean on skipjack tuna ({K}atsuwonus pelamis), yellowfin tuna ({T}hunnus albacares) and bigeye tuna ({T}hunnus obesus), revealed similar trajectories in their relative abundance. {T}he {ABBI} stands as a potentially promising alternative to enhance traditional tropical tuna stock assessments methods, as well as a new opportunity to assess the abundance of other wild species that display an associative behaviour with physical structures found in their natural environment.},
