Reported landings have varied from a minimum of 38 600 t in 2009 to a maximum of 55 500 t in 2004. In general each nation maintains a consistent proportion of the total share of annual landings. In 2015, a new data requirement was launched to specific countries exploiting cephalo- pods in ICES areas. Information on data availability is presented in Annex 3. In 2015, the CPUEs series for individual metiers and surveys were updated. The CPUE from the ARSA survey in Div. IXa as s appears to closely follow trends in LPUE from the commercial fleet. Analytical assessments were attempted for Loligo spp. in the Bay of Biscay and Sepia offic- inalis in the English Channel. Other analytical assessment possibilities have been identi- fied and work on this will continue during 2015/2016. Recent European Policies and Directives which mention cephalopods (or indirectly, affect them) have been reviewed for possible implications for fisheries, ecosystem effects and research. The need to monitor cephalopods by means of assessment, even if this assessment is not analytical is highlighted. There is a need for assessment models suitable for estimating cephalopod population levels and exploitation rate to be integrated into the forthcoming ecosystem-based fisheries assessment and management. An update is provided on the possible use of cephalopods as indicators and descriptors of GES under the MSFD, largely based on the work in the UK. This expert group is producing a literature database for recent publications on cephalo- pod biology, fisheries, and ecology. WGCEPH has progressed in its 3 year plan. ToRs and products have been redefined based on a clear direction of the group: science and advice based on two basic pillars: i) fisheries: statistics and stock status and ii) ecosystem: knowledge revision and integrated assessment. 4 | ICES WGCEPH REPORT 2015 1 Administrative details Working Group name Working Group on Cephalopod Fisheries and Life History Year of Appointment within the current cycle 2014 Reporting year within the current cycle (1, 2 or 3): Year 2 Chair(s) Marina Santurtún, Spain Jean-Paul Robin, France Meeting venue Tenerife, Spain Meeting

As whose behavior and habitat use can have substantial impacts on squid are ectothermic animals, their physiology and behavior can be ecosystems and fisheries. However, as a consequence in part of the directly linked to the physical conditions of their surrounding inherent challenges of monitoring squid in their natural marine environment (Kaplan et al., 2013; Rosa and Seibel, 2010).

Bio-logging tags provide an marine ecosystems and fisheries. Monitoring and observing squid emerging way to remotely study squid behavior in their natural behavioral patterns and vital rates can be important for ’ environments. Here, we applied a novel, high-resolution bio-logging understanding their activity and energy usage (O Dor et al., 1995; tag (ITAG) to seven veined squid, Loligo forbesii, in a controlled Pörtner, 2002), as well as for elucidating the broader ecological experimental environment to quantify their short-term (24 h) behavioral interactions between squid and the taxa they influence (e.g. foraging patterns. Tag accelerometer, magnetometer and pressure data were rates; Clarke, 1977) and how environmental changes may alter these used to develop automated gait classification algorithms based on activities (Pörtner et al., 2004; Rosa et al., 2014).

Abstract: Cartilaginous fish are commonly recognized as key species in marine ecosystems for their fundamental ecological role as top predators. Nevertheless, effective management plans for cartilagi- nous fish are still missing, due to the lack of knowledge on their abundance, distribution or even life-history. In this regard, this paper aims at providing new information on the life-history traits, such as age, maturity, reproductive period, in addition to diet characteristics of eleven rare cartilagi- Citation: Mulas, A.; Bellodi, A.; nous fish inhabiting the Central-Western Mediterranean Sea belonging to the orders Chimaeriformes Carbonara, P.; Cau, A.; (Chimaera monstrosa), Hexanchiformes (Heptranchias perlo and Hexanchus griseus), Myliobatiformes Marongiu, M.F.; Pesci, P.; Porcu, C.; Follesa, M.C.

The discriminating strategy relies on accurate design of species-specific LAMP primers within the conventional 5’ end of the mitochondrial COI DNA barcode region and allows for the identification of Loligo vulgaris among two closely related and less valuable species. The assay, coupled to rapid genomic DNA extraction, is suitable for large-scale screenings and on-site applications due to its easy procedures, with fast (30 min) and visual readout.

Synonyms There are no synonyms for Loligo vulgaris. 11.1 Geographic distribution The European squid, Loligo vulgaris Lamarck, 1798, is found in the Northeast Atlantic from ca. 55°N to ca. 20°S and throughout the Mediterra- nean (Jereb et al., 2010). It is one of the most com- mon squids in the coastal waters of the Northeast Atlantic and the Mediterranean (Worms, 1983a). In the North Sea, its distribution extends from the northwest coast of Scotland, where it is occasion- ally reported (P. R. Boyle and G. J. Pierce, pers. comm.), to the Skagerrak and Kattegat, and a few old records from the western Baltic Sea (Grimpe, 1925; Tinbergen and Verwey, 1945) are sup- ported by more recent information (Muus, 1959 in Hornbörg, 2005). A record of one specimen la- belled Bergen (Norway; 60°23’N) is described in Figure 11.1. Loligo vulgaris. Dorsal Grieg (1933). view. From Muus (1959). Loligo vulgaris was not included by Massy (1928) in her list of the Cephalopoda of the Irish coast, and an early record of occurrence in the waters of the Isle of Man (Irish Sea; Moore, 1937, in Stephen, 1944) is doubtful.

  • Feeding Ecology of Two Squid Species from the Western Mediterranean
    Vol. 531: 207–219, 2015 MARINE ECOLOGY PROGRESS SERIES Published July 2 doi: 10.3354/meps11347 Mar Ecol Prog Ser Feeding ecology of two squid species from the western Mediterranean M. Valls1,*, M. Cabanellas-Reboredo2, I. Uranga1, A. Quetglas1 1Instituto Español de Oceanografía, Centre Oceanogràfic de les Balears, Moll de Ponent s/n, Apdo. 291, 07015 Palma, Spain 2Instituto Mediterráneo de Estudios Avanzados, IMEDEA (CSIC-UIB), C/Miquel Marqués 21, 07190 Esporles, Illes Balears, Spain ABSTRACT: The squid Loligo vulgaris (LV) and L. forbesii (LF) are 2 cephalopod species occur- ring in the Atlantic Ocean and the Mediterranean Sea. Bathymetric segregation allows the co- existence of both species, with LV preferentially inhabiting the shallow shelf and LF living on the shelf-break and upper slope grounds. In this paper, the feeding habits of LV and LF were studied for the first time in the Mediterranean, by means of stomach content analysis (1452 and 900 indi- viduals of LV and LF, respectively). The main objective was to determine the diet of both species, analysing temporal and ontogenetic diet changes and inferring predator−prey interactions. Fish were by far the most important prey in both squid, followed by crustaceans and cephalopods. Prey composition revealed the bathymetric segregation of both species in the Mediterranean. Whereas LV preferentially consumed typical coastal species of sparids and gobiids, LF preyed on slope inhabitants such as myctophids and euphausiids. Ontogenetic shifts of diet occurred in both squid, but took place at contrasting sizes, suggesting that the factors triggering them might be species- specific. The diet of small-sized LV individuals was more dependent on bottom-living organisms than in large individuals, which preyed mainly on benthopelagic fish.

We conducted a com- prehensive survey of interspecific body size patterns in coastal cephalopod mollusks, covering both hemispheres in the western and eastern Atlantic. We investigated the relationship between body size and thermal energy, resource and habitat availability and depth ranges. Both latitude and depth range had a significant effect on maximum body size in each of the major cephalopod groups (cuttlefishes, squids and octopuses). We observed significant negative associations between sea surface temperature (SST) and body size. No consistent relationships between body size and either net primary productivity (NPP), habitat extent (shelf area) or environmental varia- tion (range of SST and NPP) were found.
