C43 Bass Lured Long Lines

This report describes work carried out on the North coast of Devon trialling a long line system using a range of artificial lures for bass; its evolution from conception to a full commercial application.

Appraisal of the opportunity for offshore aquaculture in UK waters

This 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.

Candian Pair Seining Experiment 1969

Biodiesel at Sea

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.

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.

Vietnam Seafood Ethics Profile

Seafish commissioned a study to assess the ethical issues impacting on seafood species landed into, and imported to the UK from a wide range of countries. This Vietnam profile looks at the main seafood products; seafood exports to UK; employment in seafood; human trafficking and forced labour indicators and rankings and research reports; ratification of international human rights and labour instruments; fisheries policy and management structure/administration; control of IUU fishing and related labour abuse; measures to protect migrant fishers; partnerships and improvement projects; and an overall assessment or criteria for overall risk assessment for Vietnam.
