Cornish Beam Trawl Diversification Project_IPF C071

With continued rising cost for fuel and no indications of prices falling back again the South West Beam trawl are looking for alternative fishing methods to target monkfish and megrims on their traditional fishing grounds. In Scottish waters many vessels target the same species using twin rig otter trawls. This project was set up to charter one of the Scottish vessels to fish the SW ground using twin rig to see if this would be a viable alternative for the SW fleet. The landings of the twin rig vessel were much less than local beam trawlers but much time was lost in exploring the beam trawl grounds for their suitability for towing with twin rig otter trawls. Despite this the catch rate for the time spent actually fishing indicates that twin rig could be a viable option in the SW. The catch profile of the twin rig is different to that of a beam trawler. Twin rig trawlers catch more higher swimming fish than beam trawlers. More knowledge of the stocks of these fish in the SW is needed to allow for otter trawling being financially viable. The discard rates recorded during the trials are not representative of discard rates for otter trawls in the area. The standard twin rig setup may need altering to better suit the SW fishing grounds and the fish species on them.

Bio-fuels for the fishing industry_Camborne School of Mines Report

This report details work carried out to investigate the performance of biofuels in marine diesel engines, relative to the use of fossil petrodiesel. The scope of work ultimately included: 1) The installation of a dynamometer test facility, equipped to run diagnostic and simulated operational duty cycles on marine diesel engines.

Development of a Generic Shellfish Hatchery Design with Associated Spatting Ponds

The SIP project output examines opportunities for aquaculture in/around enclosed marine water bodies, as well as the development of a generic design for a shellfish hatchery - the proposed Tidal Lagoon in Swansea Bay (TLSB) case study is a significant focus

Effects of electrofishing for Ensis spp. on benthic macrofauna, epifauna and fish species. SR652

This report summarises the results of experimental work carried out as part of “Design and Trials of Electrofishing System for Razorclams – FIFG 57437 and Seafish IPF funding project C85”. The aim of the project was to design and trial methods of harvesting Ensis spp. using electrical stimulus with the intention of providing a more environmentally benign alternative to existing hydraulic and toothed dredges. The results of this study demonstrate that the effects of electrofishing gear employing relatively low DC voltage and amperage can be effectively used in the harvest of Ensis spp. without serious negative effects on the epifaunal and macrofaunal benthic community.

A demonstration of "Outrigger Trawling" in the SW of England on MFV Admiral Gordon

The aim of the project was to demonstrate an alternative fishing method commonly known as Outrigger trawling. This involved replacing the heavy beam trawls which are normally towed by the vessel with two demersal trawls, each trawl spread with its own set of trawl doors and towed from the derricks. This change alone will have a significant impact on bottom and gear drag. The steady increase in fuel prices was another driver for the fleet to look at alternatives to beam trawling. By adopting the outrigger fishing method vessels can reduce their fuel consumption enabling increased profitability and a reduction in environmental impact.

Fish Waste Production in the UK - The quantities Produced and Opportunities for Better Utilisation

The options for fish waste utilisation and disposal are becoming increasingly restricted, creating a significant problem for the UK fish industry. From capture through to processing, the industry generates a significant quantity of fish waste. This report estimates the types and quantities of fish waste generated in the different sectors, from catching to processing. It then describes many of the potentially higher value utilisation opportunities for fish waste and identifies some of those that may be most suitable for the UK industry.

Greater North Sea ecoregion; demersal stock trends 2000-2015 and ICES advice 2015

This information sheet provides a brief layman's description of stock trends derived from ICES adivce in the Greater North Sea ecoregion in 2015. It also discusses fishery management for this region in relation to effort control and multi-species assessment

658 Pacific Oyster Protocol - Technical Report

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 Report and 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.

‘Off-bottom’ trawling techniques for the sustainable exploitation of non-pressure stocks in Cornish inshore waters

Review of Fish Sustainability Information Schemes Final Report

The benefits of sustainable fisheries and the need to mitigate the environmental impacts of fishing and aquaculture are increasingly in the public consciousness. Poorly implemented, government run, command and control management schemes have often failed to curb fishing effort, prevent overfishing and avoid environmental degradation. Alternative, market based approaches have shown promise and, among these, enabling informed consumer choice in seafood purchasing can generate strong motivation for improved catching and culture practices.
