Gelatinous zooplankton are a large component of the animal biomass in all marine environments, but considered to be uncommon diet most top predators. However, diets key predator groups like seabirds have conventionally been assessed from stomach content analyses, which cannot detect gelatinous prey. As predators used identify changes overall species composition ecosystems, such biases dietary assessment may impact our detection important ecosystem regime shifts. We investigated albatross...
Almost all of the world's fisheries overlap spatially and temporally with foraging seabirds, impacts that range from food supplementation (through scavenging behind vessels), to resource competition incidental mortality. The nature extent interactions between seabirds vary, as does level efficacy management mitigation. Seabird dietary studies provide information on prey diversity often identify species are also caught in fisheries, providing evidence linkages which can be used improve...
DNA methylation is a critical epigenetic regulator of development in mammals and social insects, but its significance outside these groups not understood. Here we investigated the genome-wide dynamics mollusc model, oyster Crassostrea gigas, from egg to completion organogenesis. Large-scale maps reveal that genome displays succession methylated non regions, which persist throughout development. Differentially regions (DMRs) are strongly regulated during cleavage metamorphosis. The...
Abstract Monthly sampling of cephalopod at Port-en-Bessin fish market (Normandy, France) over a 30-year period, combined with commercial fishery statistics, provides essential insight into the exploitation patterns, composition and size frequencies these resources. landings are shown to decrease which is consistent decline observed in entire French fleet operating English Channel. Cuttlefish exhibit bimodal length distribution expected for this 2-year life cycle (and two-cohort) population....
Abstract This study evaluates the relationship between both commercial and scientific spatial fisheries data a new satellite‐based estimate of potential fish production (Ocean Productivity available to Fish, OPFish) in European Seas. To construct OPFish, we used productivity frontal features derived from chlorophyll‐ horizontal gradients, which characterize 10%–20% global phytoplankton that effectively fuels higher trophic levels. OPFish is relatively consistent with distribution pelagic...
Atlantic herring in International Council for Exploration of the Sea (ICES) Divisions 6.a, 7.b-c comprises at least three populations, distinguished by temporal and spatial differences spawning, which have until recently been managed as two stocks defined geographical delineators. Outside spawning populations form mixed aggregations, are subject acoustic surveys. The inability to distinguish has prevented development separate survey indices stock assessments. A panel 45 single-nucleotide...
Abstract The English Channel cuttlefish (Sepia officinalis) is the most abundant cephalopod resource in Northeast Atlantic and one of three valuable resources for fishers. Depletion methods age-structured models have been used to assess stock, though they shown limitations related model assumptions data demand. A two-stage biomass is, therefore, proposed here using, as input data, four abundance indices derived from survey commercial trawl collected by Ifremer Cefas. suggests great...
Within the English Channel, common cuttlefish Sepia officinalis is a semelparous species for which 2-year life cycle was exclusively described in 1980s. In 1990s, new research indicated that whilst still evident females and large majority of males, small proportion males were actually maturing at only 1 year age. Since 1980, interest French UK fishers this resource has increased it nowadays one most important demersal area considered to be fully exploited. From start 20th century, fishing...
The ICES herring assessment working group (HAWG) met on an interactive virtual platform for eight days in March 2020 to assess the state of five stocks and three sprat stocks. HAWG also provided advice four sandeel but reported those prior this meeting February. conducted update assessments An analytical was performed combined North Sea Division 3.a sprat, a data limited (ICES category 3) English Channel (spr.27.7de). The autumn spawning (her.27.3a47d) SSB 2019 estimated at 1.7 mill tonnes...
Common rock oysters Saccostrea cucullata (Bivalvia) were sampled from intertidal volcanic rocks at five sites around Ascension Island (central-east Atlantic) in austral winter 2012–2014. Their left valves sectioned to reveal annual growth increments. periodicity was validated by the presence of specific marks increment sequence visible consecutive years sampling. No significant differences shell height-weight relationships revealed between sites. Marginal analysis width showed that S....
Fuelled by the raising importance of cephalopod fisheries in Europe, there have been demands from scientists and stakeholders for their assessment management. However, little has done to improve data collection order analyse populations under EU Data Collection Framework (DCF). While DCF allows member states design flexible national sampling programmes, it establishes minimum requirements (MDR) each state is obliged fulfil. In this study, was investigated whether such MDR currently set allow...
Inshore waters off the south coast of Ireland are an important foraging area for a range cetacean species. Some main prey species these cetaceans herring and sprat, two economically valuable fish in region. The Celtic Sea stock suffered marked decline 2013. present study aimed to investigate potential changes ecosystem associated determine impacts on predators. Here we analyzed sightings information common dolphins, fin, minke, humpback unidentified whale species, acoustic data environmental...
