This quick summary looks at the June 2013 ICES advice with reference to discards.

Bulletin FT3_The use of artificial seawater in mollusc purification

Seafish trials with mollusc purification have made extensive use of Artificial Seawater (ASW) in both laboratory and commercial tanks. This bulletin is aimed specifically at the use of ASW for bivalve molluscs and combines technical data from MAFF Laboratory Leaflet No. 39, published in 1977 and entitled 'Artificial Seawater for Shellfish Tanks' and experience gained by Seafish. For more detailed information the MAFF Leaflet or Seafish should be consulted.

B9_Setting welfare standards of cod during transportation to improve safety and efficiency

The investigation of the relationship between fish size, stocking density, and water quality changes during live fish transportation is expected to give information that could form the basis of an industry code of practice for marine finfish transport which would improve the safety and welfare of fish under such conditions. This report covers a second series of trials testing the effects of a range of variables on water quality during simulated transport conditions, using the cod, Gadus morhua, as the test species.

Project Inshore - Stage 3 project update March 2015

This document outlines the Project Inshore work through the four stages which progress from a broad overview of English inshore fisheries to strategic targeted action plans.

Haddock and Cod Immunology and Vaccine Development

This progress report presents the work carried out in the first two years of a three-year project on Haddock and Cod Immune System and Vaccine Development. The aim of this project is sto study the ontogeny of the immune system in Haddock and the use of this knowledge to develop a vaccine technology.

Guidance Note - Protected Wildlife Sites

There are more than 7000 protected wildlife sites in the UK, and many of these extend to the coast and inshore waters. • Some fishing activities may not have a significant impact on wildlife, some might need to be restricted in certain areas, but if so, it may be possible to find wildlife-friendly ways to keep working. • Breaking wildlife laws can result in a criminal prosecution and a fine of up to £20,000. • This Guidance Note will tell you about the protected wildlife sites in the UK, and how to work with the authorities to stay the right side of the law.

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. Keywords: Discards, North Sea, Gear selectivity, Technical measures, UK fisheries
