B18_Cod egg fatty acids project - Final report

Production of good quality juveniles from cod hatcheries relies heavily on the quality of eggs produced. However, egg quality can be highly variable and identifying, at an early stage, which eggs are likely to generate good hatch rates and larval survival can save time and money that could be wasted incubating poor quality eggs. Evidence suggests that the egg fatty acid composition, especially arachidonic acid (ARA) and docosahexaenoic acid (DHA) concentrations, as well as the ARA/eicosapentaenoic acid (EPA) ratio are vital for good egg quality. Similarly the egg carotenoid, principally astaxanthin, (Ax) content is also correlated with improved egg and larval quality in other fish species.

Fisheries Management Issues Report

The Fisheries Management Issues Report summarises some of the current issues affecting the UK fishing industry. Information is collated from regional, UK and European sources and regular topics include discussions at the EU Fisheries Council meetings, official landings into the UK relative to allocated quotas and the extent of bans on fishing due to shellfish poisoning around the UK.

A social and economic impact assessment of cockle mortality in the Burry Inlet and Three Rivers cockle fisheries, South Wales UK

Mortalities of larger, more valuable cockle 2 and 3 year-classes have recurred on the Burry Inlet (Loughour) Estuary (BI) since 2002 and on the nearby Three Rivers Estuary (TR) since 2005. The aim of this report is to estimate the economic impact of the mortality on the south Wales cockle industry, related businesses and wider Welsh economy. Stakeholder interviews, direct observation, secondary literature, production and price data supplied by industry and government agencies is used to characterise value-chains, historic livelihood, regulatory and production trends.

Biofuel for the Fishing Industry Final Report

Since 2004 the price of diesel fuel oil has increased significantly, causing many fishing vessels to become unprofitable. At the same time biofuels has increased in prominence as a long-term replacement for non renewable fossil fuels. This report details a research and development project to investigate the potential of biofuels for the fishing industry, which took place between October 05 and Jan 08. In the project two types of fuel are studied, biodiesel and pure plant oil. Over the course of the study both fuels were tested on land and at sea and proved to be technically successful. The main driver for uptake of the alternative technology in the fishing industry is economic and our study found that in most cases fossil fuels will remain more cost effective for fishing business in the short to medium term. That said there may be some opportunities in more remote communities where used vegetable oil is available and the cost of transporting diesel oil into the area push the price above that of locally produced biofuels. In terms of environmental credentials biofuels are generally sustainable but there are a number of issues which perspective purchasers need to consider which may overall green credentials of their biofuel.

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.

Use of shell in aggregates_B54

Shell waste is a major financial and operational burden on the shellfish industry. Although there are, in theory, many uses for shell, there is no singular solution to treat or utilise these materials as by-products and little infrastructure to take shell across the UK. Where infrastructure exists, it is often disjointed or only works on a localised level. Seafood processors are often unaware of potential opportunities. Most processors rely on disposal outlets which can cost up to £150 per tonne of waste making it a very costly problem. This study has undertaken an assessment of the availability of suitable shellfish waste for aggregate applications. In summary, ~43,000t of shell aggregates could be available from the current production of cockle, crab, mussel, oyster, whelk, queen and king scallops. An assessment has been made regarding the availability of these different shell types, market opportunities, technologies to treat the shell and costs.
