For 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. Tropical 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. Addressing this concern, we developed the Associative Behaviour-Based abundance Index (ABBI), designed to provide direct abundance estimates for animals, which exhibit an associative behaviour with aggregation sites. Its implementation in the western Indian Ocean on skipjack tuna (<i>Katsuwonus pelamis</i>), yellowfin tuna (<i>Thunnus albacares</i>) and bigeye tuna (<i>Thunnus obesus</i>), revealed similar trajectories in their relative abundance. The 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.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Direct assessment of tropical tuna abundance from their associative behaviour around floating objects","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-03 01:32:18.524960","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"direct abundance index, associative behaviour, tropical tunas, echosounder buoys","OtherDescriptors":null,"Notes":null,"AnaPub":2024,"MonPub":null,"DateUpdate":"2025-09-18","DateCreate":"2025-03-04","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:001294554900003","VABBcode":null,"OpenAcc":1,"DOI":"10.1098/rspb.2024.1132"},"refs":null,"anarec":{"AnaID":405960,"PubliDate":2024,"Pagination":"20241132","XtraPublOfAnaID":null,"ISBN":null,"Volume":"291","Issue":"2029","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":204863,"SerRR":"Proceedings of the Royal Society of London.
