SR624_The survival of skates (Rajidae) caught by demersal trawlers fishing in UK waters_IPF B007 and C107

Skates and rays are a common component of mixed demersal fisheries, and large quantities may be discarded. Given their biological vulnerability, understanding the fate of these elasmobranchs is of management concern. Estimates of discard survival are needed for modelling the possible benefits of management measures. In this study, the focus is on the Bristol Channel skate fishery, where on-board holding tanks were used to assess the short-term rates of survival of trawl-caught skates (Rajidae). From monitoring the survival rates of 162 fish kept in specially designed on-board holding tanks for periods of up to 72 h, the short-term rate of survival was 55%. Keywords: Otter trawl, Ray, Skate.

Discarding in the North Sea and on the historical efficacy of gear-based technical measures in reducing discards

We describe and analyse newly available catch and discard data from the English andWelsh fishing fleet operating in the North Sea. In this fleet we estimate that between 2003 and 2006 discard rates averaged 36% by number and 25% by weight. Additionally, we analyse historical discard data from the fleet to evaluate the efficacy of square-mesh panels and increases in codend mesh size. These various gear-based technical measures have been introduced into the fisheries for the purpose of reducing discarding; we demonstrate that these technical measures have been effective in this respect.

Seafood Imports - Legislation and Official Procedures - Questions and Answers

Import controls are in place to protect human and animal health. Food originating outside the UK may have been produced to different standards to the ones in force throughout the EU. Border controls ensure that only food that meets national food safety legislation, and therefore poses no risk to public health, is allowed into the country. Examples of food that would be stopped at the border are fish containing unacceptable levels of mercury, or shellfish containing natural toxins.

Economics of Potential Systems for Farmed Production of Cod

Experimentation with the cultivation of cod has a history going back more than a century and the potential for developing commercial cod production has been the subject of a number of studies over the past 15 years. Most of these studies have concluded that production of cod does not appear viable in general under the most likely assumptions of performance and price in prospect at the time. However, the most recent report prepared by Nautilus draws much more favourable conclusions on the prospects for viability.

Seafish response to A Strategy for Marine Nature Conservation in Scotland and Guidelines on the selection of MPAs and development of the MPA network

Seafish has produced a combined response to two Scottish consultations on the future of the Scottish marine environment. The consultations were on the draft Marine Nature Conservation Strategy for Scotland and on draft guidelines on the selection of Marine Protected Areas (MPAs) and the development of the MPA network in the seas around Scotland. The original consultation papers can be found here: A Strategy for Marine Nature Conservation in Scotland: http://www.scotland.gov.uk/Topics/marine/marine-environment/Conservationstrategy/draftconstrategy Marine Protected Areas in the Seas around Scotland: http://www.scotland.gov.uk/Topics/marine/marine-environment/mpanetwork/draftmpaguide
