Recent studies have shown that coastal and shelf cephalopod populations increased globally over the last six decades. Although landings are dominated by squid fishery, which represents nearly 80% of worldwide catches, octopuses cuttlefishes represent ∼10% each. Total reported global production past three decades indicates a relatively steady increase in catch, almost doubling from 179,042 t 1980 to 355,239 2014. Octopus fisheries likely continue grow importance magnitude as many finfish...
Abstract The Northern Humboldt Current System sustains one of the most productive fisheries in world. However, climate change is anticipated to negatively affect fish production this region over next few decades, and detailed analyses for many fishery resources are unavailable. We implemented a trait-based Climate Vulnerability Assessment based on expert elicitation estimate relative vulnerability 28 (benthic, demersal, pelagic) impacts by 2055; ten exposure factors (e.g., temperature,...

Understanding the response of any species to climate change can be challenging. However, in short-lived faster turnover generations may facilitate examination responses associated with longer-term environmental change. Octopus tetricus, a commercially important species, has undergone recent polewards range shift coastal waters south-eastern Australia, thought southerly extension warm East Australian Current. At cooler temperatures distribution limit, growth could slower, potentially leading...
Shifts in species distribution, or 'range shifts', are one of the most commonly documented responses to ocean warming, with important consequences for function and structure ecosystems, socio-economic activities. Understanding genetic signatures range shifts can help build our knowledge capacity establish persist colonised areas. Here, seven microsatellite loci were used examine population connectivity, diversity Octopus tetricus, which has extended its distribution several hundred...
To persist in the face of environmental change, species must adjust to new conditions or change their geographical distribution, e.g. by range extension. Success for individuals within a zone extension requires environment support capacity produce viable gametes and survival offspring. Reproductive characteristics polewards range-shifting Octopus tetricus were examined off north-eastern Tasmania, Australia, assess whether it is likely successfully establish this extended area its range....

The Peruvian Upwelling Ecosystem (PUE) is one of the most productive ecosystem in world terms productivity and fish catches, partly because its geographical location affected by remote physical processes, such as interannual climate variability Equatorial Pacific Ocean (EPO), whose dominant signal El Niño Southern Oscillation (ENSO). In order to assess thermal effects ENSO off Peru, a Coastal Thermal Index (PCTI) was developed representing 87.7% total variation Sea Surface Temperature (SST)...
Abstract. The rhynchoteuthion stage of the jumbo squid, Dosidicus gigas , has morphological characteristics similar to paralarvae purpleback Sthenoteuthis oualaniensis making it difficult determine locations, seasons, and conditions where spawning squid occurs. In this study, 180 D. were collected off west coast Baja California peninsula identified by sequencing a 369‐bp fragment cytochrome oxidase I gene. Of these, 77 specimens, 0.8–6.0 mm in mantle length, described. Indices based on...

Specimens of the uncommon luminous flying squid Eucleoteuthis luminosa were collected off west coast Baja California peninsula during 2004, 2005, and 2008. The morphology morphometry adults, juveniles, paralarvae this species, as well oceanographic conditions specimen sampling are described. Adults 1 juvenile in surface waters both day (20.5°C sea temperature (SST); 0.15 mg/m3 0.55 chlorophyll-a (Chl-a), respectively) night (24°C SST, 0.08 Chl-a).

The objective of present study was validate predictive ability a regional configuration PISCES model on main variables Humboldt Current Large Marine Ecosystem (HCLME). statistical indicators evaluate were bias, root-mean-square error, correlation coefficient and, graphically, Taylor’s diagram. results showed that reproduces dynamics (chlorophyll, dissolved oxygen nutrients); particular, impact El...
Abstract Marine biota is redistributing at a rapid pace in response to climate change and shifting seascapes. While changes fish populations community structure threaten the sustainability of fisheries, our capacity adapt by tracking projecting marine species remains challenge due data discontinuities biological observations, lack availability, mismatch between real distributions. To assess extent this challenge, we review global status accessibility ongoing scientific bottom trawl surveys....
The common Sydney octopus Octopus tetricus has undergone range extension along the east coast of Australia, associated with regional warming and strengthening southward East Australian Current (EAC). Its historical distribution is from southern Queensland to New South Wales, but it now also found off north-east Tasmania, where may affect local ecosystem dynamics due changes in trophic interactions. This study aims identify prey level O. specimens collected Tasmania anticipate potential...
