Chapter 1 provides the Terms of Reference and the list of participants. Chapter 2 provides an overview of Community fisheries that catch elasmobranchs :,O3 1, 8). It gives an pdated description of the commercial and recreational fisheries for elasmobranchs in the Northeast Atlantic :Section 2.1), Mediterranean Sea :Section 2.2) and for Community fisheries that catch elasmobranchs in other waters :Section 2.3). ,hese descriptions were also given in the previous report of this s bgroup :S,EC8 2002), but have now been pdated, specifically with regards to more detailed landings data, and a more complete description of the fisheries in the Mediterranean.

  • Spatial Ecology and Fisheries Interactions of Rajidae in the Uk
    UNIVERSITY OF SOUTHAMPTON FACULTY OF NATURAL AND ENVIRONMENTAL SCIENCES Ocean and Earth Sciences SPATIAL ECOLOGY AND FISHERIES INTERACTIONS OF RAJIDAE IN THE UK Samantha Jane Simpson Thesis for the degree of DOCTOR OF PHILOSOPHY APRIL 2018 UNIVERSITY OF SOUTHAMPTON 1 2 UNIVERSITY OF SOUTHAMPTON ABSTRACT FACULTY OF NATURAL AND ENVIRONMENTAL SCIENCES Ocean and Earth Sciences Doctor of Philosophy FINE-SCALE SPATIAL ECOLOGY AND FISHERIES INTERACTIONS OF RAJIDAE IN UK WATERS by Samantha Jane Simpson The spatial occurrence of a species is a fundamental part of its ecology, playing a role in shaping the evolution of its life history, driving population level processes and species interactions. Within this spatial occurrence, species may show a tendency to occupy areas with particular abiotic or biotic factors, known as a habitat association. In addition some species have the capacity to select preferred habitat at a particular time and, when species are sympatric, resource partitioning can allow their coexistence and reduce competition among them. The Rajidae (skate) are cryptic benthic mesopredators, which bury in the sediment for extended periods of time with some species inhabiting turbid coastal waters in higher latitudes. Consequently, identifying skate fine-scale spatial ecology is challenging and has lacked detailed study, despite them being commercially important species in the UK, as well as being at risk of population decline due to overfishing. This research aimed to examine the fine-scale spatial occurrence, habitat selection and resource partitioning among the four skates across a coastal area off Plymouth, UK, in the western English Channel. In addition, I investigated the interaction of Rajidae with commercial fisheries to determine if interactions between species were different and whether existing management measures are effective.

Embora, existam algumas pescarias dirigidas a espécies de elasmobrânquios com carácter sazonal e/ou local ao largo das ilhas Britânicas, os elasmobrânquios são comunemente capturados em pescarias mistas demersais. A pescaria da palangre dirigida a espécies demersais é conhecida por ser altamente selectiva para certas espécies de elasmobrânquios, embora os padrões espaciais e temporais destas pescarias não tenham, ainda, sido descritos. Por conseguinte, uma descrição geral destas pescarias ao largo das ilhas britânicas foi conduzida. As principais zonas, em termos de desembarques na pescaria da palangre demersal (1990-2007) foram o sul do Mar do Norte (ICES IVc), Mar da Irlanda (VIIa) e Mar do Norte central (IVb). Enquanto que, as principais espécies capturadas nestas pescarias são o galhudo- malhado, bacalhau do Atlântico, raias e safio. Desde 2007, as capturas acessórias de raias no Mar do Norte têm uma quota de 25%, a qual foi revista recentemente, sendo apenas obrigatória para as embarcações com mais de 15 m de comprimento total (Regulamento CE n.

  • Book of Abstracts: 6Th Annual Meeting of the European Elasmobranch Association 2002
    6th Annual European Elasmobranch Association Conference Book of Abstracts: 6th Annual Meeting of the European Elasmobranch Association 2002 9.35 –10.45 Welsh Skate and Ray Project H. Jones, N.K. Dulvy, P.J. Coates and C. Eno Annual landings of ray species (Rajidae) in England and Wales have fallen from around 18,000 to 3,000 tonnes over the last 40 years. The cause of the decline is believed to be largely due to over-fishing, particularly from the use of trawl gears. The Bristol Channel area is of particular importance and used to account for around 25-30% of UK landings. Common skate (Dipturus batis) was once a frequent catch but is now commercially extinct. Although data is incomplete larger ray species Raja brachyura (blonde) and R. clavata (thornback) have apparently declined in both abundance and average size, to be partly replaced by the smaller species R. montagui (spotted) and Leucoraja naevus (Cuckoo). Fishery Managers face the challenge of identifying practical conservation measures that need to be acceptable to the majority if they are to be effective. Options include: • Size restrictions i.e. minimum and/or maximum size (and options by species or sex and whether applied to part or whole fish). • Restricted licencing of vessel effort or catch (quotas). • Technical measures e.g. mesh sizes, vessel size, gear type. • Gear restrictions (e.g. by location and/or time). • No take or limited take zones (e.g. no taking of female rays). As well as being of commercial value, rays are also of wider recreational and conservation interest and a unique group of interested parties in Wales have come together to address a "common cause".

Front cover images: Jim Elis (Cefas). Executive Summary Approximately 14 species of skate (Rajidae) occur on the continental shelf of the United Kingdom. These species vary in their commercial importance and also their susceptibilities to over-exploitation. Stocks of some skate species are considered healthy, whereas some of the larger-bodied species have declined or disappeared from parts of their former range. The assessment and management advice for skates has been hampered by a lack of species- specific data from commercial fisheries.

  • Fish and Shellfish
    Offshore Energy SEA 3: Appendix 1 Environmental Baseline A1a.4 Fish and Shellfish A1a.4.1 Introduction This section describes the distribution and ecology of fish and commercially important shellfish species in UK waters, with reference, where information is available, to spawning and nursery grounds. The section draws on previous fishery studies commissioned for the SEA programme and a range of other technical reports and scientific publications. Information on the seasonal distribution of commercially important fish and shellfish is available from several sources, with the most reliable being the routine research vessel surveys undertaken by European research laboratories, co-ordinated by the International Council for the Exploration of the Sea (ICES). These annual surveys target major commercial species but they also record information on the distribution and abundance of the non-target components of the catch. The recently published Fish Atlas of the Celtic Sea, North Sea and Baltic Sea (Heessen et al. 2015) synthesises results from these international research surveys, incorporating data from over 70,000 hauls carried out between 1977-2013. A1a.4.2 UK context Over 330 species of fish have been recorded on the UK continental shelf and the deep water regions which lie to the north and west of Scotland are home to many more. The following sections give a brief overview of a selection of abundant and widespread species in UK waters, grouped into pelagic (open water), demersal (bottom dwelling), elasmobranch (sharks and rays), diadromous (migrate between the sea and freshwater to spawn) and shellfish species. A1a.4.2.1 Pelagic species Mackerel (Scomber scombrus) are widely distributed around the north-east Atlantic where they tend to shoal in large schools in waters down to 1,000m deep.
