Considerable uncertainty remains over how increasing atmospheric CO2 and anthropogenic climate changes are affecting open-ocean marine ecosystems from phytoplankton to top predators. Biological time series data thus urgently needed for the world's oceans. Here, we use carbon stable isotope composition of tuna provide a first insight into existence global trends in complex ecosystem dynamics oceanic cycle. From 2000 2015, considerable declines δ13 C values 0.8‰-2.5‰ were observed across three...
Abstract The Atlantic bluefin tuna is a highly migratory species emblematic of the challenges associated with shared fisheries management. In an effort to resolve species’ stock dynamics, genomewide search for spatially informative single nucleotide polymorphisms ( SNP s) was undertaken, by way sequencing reduced representation libraries. An allele frequency approach discovery used, combining data 555 larvae and young‐of‐the‐year LYOY ) into pools representing major geographical areas...
Among the various challenges facing tropical tuna purse seine fleet are need to reduce fuel consumption and carbon footprint, as well minimising bycatch of vulnerable species. Tools designed for forecasting optimum fishing grounds can contribute adapting changes in fish distribution due climate change, by identifying location new suitable grounds, thus reducing search time. While information about high probability find species could result a reduction. The present study aims at contributing...
In the present study we have investigated population genetic structure of albacore (Thunnus alalunga, Bonnaterre 1788) and assessed loss diversity, likely due to overfishing, in North Atlantic Ocean. For this purpose, 1,331 individuals from 26 worldwide locations were analyzed by genotyping 75 novel nuclear SNPs. Our results indicated existence four genetically homogeneous populations delimited within Mediterranean Sea, Ocean, Indian Ocean Pacific Current definition stocks allows sustainable...

Abstract Movement patterns of 17 bigeye tuna ( Thunnus obesus ) near the Azores Islands were analyzed between April and May 2001 2002 using pop‐up satellite archival tags. Despite short attachment durations (1 to 21 days, 8.2 days on average), their vertical movements revealed much shallower distribution in comparison with previous studies tropical Pacific Atlantic. Depth temperature histograms unimodal, although overall depth during day was deeper than night due daily incursions waters....
Abstract From 2005 to 2010, 136 internal archival tags and 29 pop-up satellite were used track juvenile Atlantic bluefin tuna in the Bay of Biscay. Information from 15 5 was recovered. The analysis adapted for a common treatment both types tag data, allowing classification overwintering distribution patterns, fidelity Biscay feeding area, as well horizontal vertical habitat utilization. Results show substantial geographic dispersion autumn spring, with high concentration during summer, when...
Albacore (Thunnus alalunga) in the North Atlantic Ocean is currently managed as a single well-mixed stock, although this assumption remains contentious. We measured stable isotopes (δ13C and δ18O) trace elements (Mg, Mn, Sr, Ba) otoliths of albacore collected from two feeding grounds, namely Bay Biscay offshore waters, compared them among sampling locations life history stages. Measurements otolith core, post-core edge were used to determine whether these regions have same nursery origin...
The commercially important Atlantic bluefin tuna (Thunnus thynnus), a large migratory fish, has experienced notable recovery aided by accurate resource assessment and effective fisheries management efforts. Traditionally, this species been perceived as consisting of eastern western populations, spawning respectively in the Mediterranean Sea Gulf Mexico, with mixing occurring throughout Atlantic. However, recent studies have challenged assumption revealing weak genetic differentiation...
