“…Here, we found that the minimum preferred value was 4.4 ml.l −1 (196 mmol.m −3 ) which is consistent with previous findings, noting that the present study area is smaller and in this case, the threshold relates to preference not survival. The preferred range for MLD ranged from 6 to 158 m and is consistent with the distributions found by Arrizabalaga et al (2015) and Tanabe et al (2017). Our observed minimum limit appears to be near the extreme observed level.…”

“…The preferred SST range we identified (21.6-30.0 • C) is nearly identical to the extreme SST range measured at-sea by the French purse seine fleet at SKJ set locations (21.5-30.0 • C; IRD, unpublished data). A similar range was also obtained from the fishery-independent (Lopez et al, 2017) and fishery-dependent based preference models developed for SKJ (Andrade, 2003;Arrizabalaga et al, 2015;Tanabe et al, 2017). For O 2 , Barkley et al (1978) found that a minimum value of 3-3.5 ml.l −1 (134-156 mmol.m −3 ) was necessary for the long-term survival of SKJ while Arrizabalaga et al (2015) found that a value around 3.8 ml.l −1 (170 mmol.m −3 ) was preferred by for SKJ across the world's oceans.…”

“…These features are commonly associated with enhanced primary productivity and thus, prey aggregation (Polovina et al, 2006;Benitez-Nelson et al, 2007;Tew Kai and Marsac, 2010;Bakun, 2013). Tropical tunas live in warmer, less productive environments that display near null or positive SSHa values whereas temperate tuna species are associated with negative SSHa values (Teo and Block, 2010;Arrizabalaga et al, 2015;Lopez et al, 2017). Sea surface salinity (SSS), sea surface current intensity (SSC), sea surface dissolved oxygen (O 2 ), and mixed layer depth (MLD) also have been shown to affect SKJ distribution at different spatio-temporal scales (Dizon, 1977;Barkley et al, 1978;Evans et al, 1981;Lopez et al, 2017, see also section Introduction) and were also included in our analysis.…”

“…These characteristics all facilitate SKJ's ability to make rapid vertical movements (Wild and Hampton, 1994). SKJ habitat is associated with a sea surface temperature (SST) range between 18 and 30 • C (Barkley et al, 1978), with a preferred range between 23 and 28 • C (e.g., Arrizabalaga et al, 2015). As SKJ have a limited ability to thermoregulate, suitable habitat is restricted to water masses that are relatively warm, have a high oxygen content and are close to cooler waters (below the thermocline) in order that they can release any excess metabolic heat.…”

Skipjack Tuna Availability for Purse Seine Fisheries Is Driven by Suitable Feeding Habitat Dynamics in the Atlantic and Indian Oceans

An Ecological Niche model was developed for skipjack tuna (Katsuwonus pelamis, SKJ) in the Eastern Central Atlantic Ocean (AO) and Western Indian Ocean (IO) using an extensive set of presence data collected by the European purse seine fleet (1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014).Chlorophyll-a fronts were used as proxy for food availability while mixed layer depth, sea surface temperature, dissolved oxygen, salinity, current intensity, and height anomaly variables were selected to describe SKJ's abiotic environmental preferences. The resultant ecological niche included both mesoscale eddy-type productive features that displayed latitudinal range in the IO to large scale upwelling systems that shrink and swell seasonally in the AO. Overall, 83% of all free swimming school sets (FSC) and 75% of drifting fish aggregating device sets (dFAD) that contained SKJ occurred within 25 km of favorable feeding habitat. In the AO, 34% of dFAD sets were made more than 100 km away from this habitat, mostly in the surface chlorophyll-a poor environment of the Guinea Current. These distant sets represent 10% of dFAD sets in the IO and 8% of all FSC sets. Our results suggest that the Mozambique Channel in the IO, with its simultaneously favorable feeding and spawning conditions, may seasonally offer a better SKJ nursery habitat than the Guinea Current which shows a substantially poorer feeding capacity. With the exception of this latter area, our results also suggest that fishing accessibility will be higher in months where the size of the favorable feeding habitats are reduced, likely because this reduction drives a geographical contraction in SKJ populations. The observed relationship between the annual size of favorable feeding habitat and both annual catch rates and total catches in the IO is consistent with the near-full exploitation of this stock that has occurred since the 2000s. Moreover, it suggests that annual habitat size could be used as an indicator of growth capacity for this highly productive stock. Habitat monitoring, as part of a dynamic fisheries management approach, should contribute to the sustainable exploitation of SKJ by providing information on the climate-dependent aspects of stock variability and the effects of dFAD deployment in food-rich habitats.

Ecosystems and biodiversity across the world are being altered by human activities. Habitat modification and degradation are among the most important drivers of biodiversity loss. These modifications can have an impact on species behavior, which can, in turn, impact their mortality. While several studies have investigated the impacts of habitat degradation and fragmentation on terrestrial species, the extent to which habitat modifications affect the behavior and fitness of marine species is still largely unknown, particularly for pelagic species. Since the early 1990s, industrial purse seine vessels targeting tuna have started deploying artificial floating objects—Drifting Fish Aggregating Devices (DFADs)—in all oceans to increase tuna catchability. Since then, the massive deployment of DFADs has modified tuna surface habitat, by increasing the density of floating objects, with potential impacts on tuna associative behavior and mortality. In this study, we investigate these impacts for yellowfin tuna in the Indian Ocean. Using an individual‐based model based on a correlated random walk and newly available data on DFAD densities, we quantify for the first time how the increase in floating object density, due to DFAD use, affects the percentage of time that yellowfin tuna spend associated, which, in turn, directly impacts their availability to fishers and fishing mortality. This modification of tuna associative behavior could also have indirect impacts on their fitness, by retaining tuna in areas detrimental to them or disrupting schooling behavior. Hence, there is an urgent need to further investigate DFAD impacts on tuna behavior, in particular, taking social behavior into account, and to continue regulation efforts on DFAD use and monitoring.
