Modification to Specification

This report will look at alternative materials and then consider design modifications for the mat.Secondly, it will investigate possible alternative materials and heat treatments for the net and finally design modifications to the net to capitalise on any advantage these materials may offer. This report should be read in conjunction with SR612_Testing Materials used in Queen Scallop dredge Construction_IPF C100

This guide looks at the interactions between protected species and fisheries, providing information on potential mitigation options.

The study covered fisheries from northwest Norway through the North Sea, English Channel/la Manche, Cantabrian Sea and Algarve to the French Mediterranean. It was carried out as a series of tasks. Task 1, preparation, involved reviewing each partner’s national fisheries and establishing liaison groups of fishermen and other industry members; Task 2, quantifying lost gear, required the partners to interview fishermen to establish their experiences of gear loss and then the survey the areas where losses were reported; Task 3, physical evolution, started with the retrieval of ‘naturally lost’ gears and then moved on to a series of exercises simulating gear loss and monitoring how the ‘lost’ gears changed over time; Task 4, ecosystem impacts, involved interpreting catch data from the experimental gears, raising the data to métier level and comparing the results to targeted commercial catches; Task 5, mitigating measures, established a sub-group to look at the ways in which gear loss is treated elsewhere, matched those approaches to the European fisheries and assessed the likely benefits of alternate strategies; Task 6, ran throughout the project and involved industry liaison, reporting and other dissemination. The work required a relatively high level of industry liaison. In practical terms this meant that each national partner set up a national advisory group (NAG) to guide the work and to ensure that the sea trials and recommendations were representative and realistic. The NAGs were mainly made up of experienced skippers but also included net riggers and other professionals as appropriate. This report, wherever possible, follows the sequence of tasks described above.

Since 1987 the Northern Prawn Fishery (NPF) fleet has towed double rigs (two nets). Prior to this most trawlers towed quad rig (four nets). To improve economic efficiency in the fishery there is great interest to again allow the use of quad rig.

The report provides an assessment of the potential for open ocean, offshore finfish aquaculture in UK waters using candidate species which would have similar growth and performance characteristics to Atlantic salmon (Salmo salar) and Atlantic cod (Gadus morhua)and with due reference to other potential species candidates.

The potential impact of wild Pacific oysters on local biodiversity is being raised as an issue that has to be considered in environmental assessments of both new farms and changes to practices by existing farms where they occur in wildlife protected areas. A FIFG-funded project has been carried out by Seafish which focuses on Pacific oyster cultivation in and around European Marine Sites. Working closely with industry and statutory nature conservation agencies, relevant background information was collated (Development of a Pacific oyster aquaculture protocol for the UK - Technical Reportand a protocol proposed (Development of a Pacific oyster aquaculture protocol for the UK - Protocol template. Where there could be an impact on protected wildlife and/or marine habitats, husbandry and management techniques have been proposed to mitigate or eliminate any potential impacts. The project complements the ‘Memorandum of Understanding for Appropriate Assessments in European Marine Sites’ that was agreed between the SAGB and Natural England.

This report provides a national strategic overview of the findings and recommendations 2. provided in the 9 IFCA specific Strategic Sustainability Reviews which were the primary focus of Stage 3 of Project Inshore. In addition, the national overview report provides the opportunity to highlight those stocks which straddle the inshore boundary (6nm) and have therefore not been the focus of the IFCA specific reports.

This document provides a non-technical summary of sea trials in a ~10 m class potting vessel running comparative fuel consumption tests using red (fossil) diesel and biodiesel. The vessel, FV Ma Gandole, is powered by a 20 year old Volvo MD70B 6 cylinder, normally aspirated, 120 hp diesel engine coupled to a 3:1 reduction gearbox, assumed to be fairly typical of many power plant of the Newlyn ~10 m class fleet. The sea trials demonstrated that both fuels started the engine equally well, and the vessel was felt to handle and perform equally well with either fuel.
