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.

Fuel Flow Metering for Fishing Vessels Phase-1 Preliminary Report

The objective of the Phase 1 work was to assess the available technology in terms of quoted specification, cost, transducer type and installation requirements, with a view to selecting devices to test. Work on Phase 1 formally started on 21 July 2008 and the agreed duration for the complete project was 2-3 months. From early discussions with suppliers of fuel flow meters, it became apparent that lead times for the supply of certain meters could be as much as one month. Given the proposed project duration and these supply times, it was vital to expedite decisions on which fuel meters would be tested within the programme. This report summarises findings thus far during Phase 1 of the work, to allow devices with long supply lead times to be ordered in time to ensure the project will complete to schedule. Decisions made on the devices to be tested are reported herein. These devices were selected in consultation with a representative SeaFISH during a meeting held on 24th July. As it is presented at a very preliminary stage of the work, it should be appreciated that the materials presented herein may be revised by the time of presentation of the final project report. The research team have already encountered one result that will significantly effect the direction of the work.

Fisheries Resource Access Mapping Project: The Co. Down Wind Resource Zone

This report presents an assessment of the importance to the Northern Ireland fishing industry of the Wind Resource Zone (WRZ) off the County Down coast. This work is an early output from FishRAMP being undertaken by the Agri-Food and Biosciences Institute (AFBI) and Poseidon with input from the NI seafood industry through the Seafish Northern Ireland Advisory Committee (SNIAC) as well as funding and support from Seafish and DARD.

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.

Responsible Fishing Scheme Version 2 - Terms of Reference

The Responsible Fishing Scheme (RFS) Version 2 Terms of Reference is a document which outlines the objectives, structure and scope for the new version of the RFS. Created through collaboration between Seafish and Global Seafood Assurances (GSA), the Terms of Reference (ToR) provides an overview of the RFS V2 standard development process, including a summary of the feedback received from extensive consultation involving a wide range of UK seafood sector and international stakeholders.

Culturing of Norway lobster (Nephrops norvegicus)_Aggression in Nephrops

The first aim of this project was to examine and gain a better understanding of the aggressive behaviour of the animals. Aggressive behaviour, causing injury or death, is thought to be a major obstacle in keeping animals in communal tanks. It was found that the Norway lobsters are able to build a dominance hierarchy, which reduces overall aggression in communal tanks. Moreover, it was found that pheromones are necessary for establishing dominance. Follow up studies will aim to gain a better understanding of the role of aggression in natural behaviour including territoriality,resource competition and mate choice. The second aim is to develop economic holding conditions for the animals. Holding animals in communal tanks is thought to be easier to manage - in terms of feeding and maintaining good water quality - than keeping them separately. Ongoing experiments comparing holding conditions indicate that there seems to be no difference in survival rate between individual and communal holding conditions. The third aim is to decide upon the best methods of collecting eggs and to hatch them. This will be researched in the next two years. Eggs will be collected by catching berried females. Holding conditions will be tested to maximize the hatching rate of the four larval stages in the lab. The results of the study will improve the understanding of the species which could help drive better stock management. In addition, it could support the fishing industry by providing sustainability and reducing the influence of natural barriers to fishing, such as weather conditions.
