“…Straddling stocks are shared among exclusive economic zones (EEZs) and high seas, but approximately 40 % of the world's tuna are caught in the high seas, providing a challenge to their conservation and management (Allen et al 2010). Such a situation poses conservation and management issues of jurisdiction under international law and multilateral cooperation to define property rights and management actions (Aranda et al 2012). Such management actions need to consider the real and potential impact according to their expected outcome.…”

The failure to achieve fisheries management objectives has been broadly discussed in international meetings. Measuring the effects of fishery regulations is difficult due to the lack of detailed information. The yellowfin tuna fishery in the eastern Pacific Ocean offers an opportunity to evaluate the fishers' responses to temporal regulations. We used data from observers on-board Mexican purse-seine fleet, which is the main fleet fishing on dolphin-associated tuna schools. In 2002, the InterAmerican Tropical Tuna Commission implemented a closed season to reduce fishing effort for this fishery. For the period 1992-2008, we analysed three fishery indicators using generalized estimating equations to evaluate the fishers' response to the closure. We found that purseseiners decreased their time spent in port, increased their fishing sets, and maintained their proportion of successful fishing sets. Our results highlight the relevance of accounting for the fisher behaviour to understand fisheries dynamics when establishing management regulations.

“…Central to the UNFSA is the promotion of science-based and precautionary approaches to set limit reference points for fishing effort. 1 But in spite of these requirements for RFMOs being clearly set out in the UNFSA their application has remained patchy at best (see Aranda et al 2012). …”

“…Havice et al 2010, Aranda et al 2012, Bruyn et al 2013 argue that the adoption (or not) of HCRs and reference points by RFMOs is a function of the (mis)alignment of political and economic goals of participating states given their vested interests in different species of tuna, the fishing gears used to catch them and the protection of often long standing access arrangements (see also Bailey et al, 2013. In other words, at the RFMO levels, these studies claim that the old tuna regimes or institutions have largely failed to provide adequate incentives for states and fishing industries to agree to precautionary approaches.…”

“…In old tuna regimes it is apparent that cooperation is undermined by the diversity and dynamism of the actors involved -the more diverse and dynamic the less effective it can become in achieving its (conservation) goals (Wangler et al 2012). The WCPO, with its many regional treaties has been a case in point: weak cooperation has led to weak compliance (see also CullisSuzuki and Pauly 2010; Aranda et al 2012). But building on the work of Havice (2010Havice ( , 2013 the results also show that the VDS has been central to creating improved cooperation by delivering incentives to the PNA states, which has in turn brought about greater stability of the sub-regional PNA as a new tuna regime.…”

“…However, the complex nature of tuna fisheries, including multiple species and gear types, contributes to the difficulties in member states cooperating for these sustainable management. As Aranda et al (2012) argue, the adoption (or not) of HCRs and reference points by RFMOs is a function of the (mis)alignment of political and economic goals of participating states given their vested interests in different species of tuna, the fishing gears used to catch them and the protection of often long standing access arrangements (see also Bailey et al 2013.…”

Yellowfin tuna (Thunnus albacares; YFT) is an apex marine predator inhabiting tropical and subtropical pelagic waters. It supports the second largest tuna fishery in the world. Here, we review the available literature on YFT to provide a detailed overview of the current knowledge of its biology, ecology, fisheries status, stock structure and management, at global scale. YFT are characterized by several peculiar anatomical and physiological traits that allow them to survive in the oligotrophic waters of the pelagic realm. They are opportunistic feeders, which allows fast growth and high reproductive outputs. Globally, YFT fisheries have expanded over the last century, progressively moving from coastal areas into the majority of sub-tropical and tropical waters. This expansion has led to a rapid increase in global commercial landings, which are predominantly harvested by industrial longline and purse seine fleets. For management purposes, YFT is divided into four stocks, each of which is currently managed by a separate tuna Regional Fisheries Management Organization. Our current understanding of YFT stock structure is, however, still uncertain, with conflicting evidence arising from genetic and tagging studies. There is, moreover, little information about their complex life-history traits or the interactions of YFT populations with spatio-temporally variable oceanographic conditions currently considered in stock assessments. What information is available, is often conflicting at the global scale. Finally, we suggest
