Última Accumulation and mobilization of lipids in relation to reproduction of yellowfin tuna (Thunnus albacares) in the Western Indian Ocean ArchiMer Zudaire, Iker; Murua, Hilario; Grande, Maitane; Pernet, Fabrice; Bodin, Nathalie. Total lipid content and lipid class composition were analyzed in gonads, liver and white muscle of yellowfin tuna (Thunnus albacares) throughout ovary development to understand its reproductive allocation strategy and to assess the relation between female condition and reproduction. A total of 112 females were collected onboard purse-seiner in the Western Indian Ocean from January to March 2009, from June to July 2009, and from April to May 2010. Gonads were characterized by highly variable total lipid contents ranging from 5 to 27 μg mg−1 of wet weight (ww) with a predominance of neutral lipids, mainly triacylglycerols (TAG) and sterol- and wax-esters. The different lipid classes in gonads described an accumulative pattern through the maturity process...

This paper presents an associative behavior-based abundance index (ABBI) providing direct estimates of the abundance of yellowfin tuna (Thunnus albacares) based on their associative behavior around floating objects (FOBs). Considering the associative dynamics of small yellowfin tuna individuals (<10 kg) at FOBs through residence and absence times at FOBs, together with acoustic data obtained from fisher’s echosounder buoys, the ABBI index is derived for yellowfin tuna in the western Indian Ocean over the period 2013-2019. This index accounts for both the FOB-associated and free-swimming components of the tuna populations, as well as for the effects of increasing numbers of FOBs on each component.
