Throughout much of the UK, the native oyster remains in a severely depleted state in the wild, having suffered for two centuries with over-exploitation, pests, disease, pollution and harsh winters. The native oyster is a Biodiversity Action Plan Species. Native oyster beds can form a flourishing part of the ecosystem, with many associated species. A significant driver for restoration of native oyster beds should therefore be re-creating and conserving an ecological resource in order to re-establish a biotope that was once common and covered wide areas of the UK inshore seabed.

The large scale growth in salmon production in the UK has resulted in most available near shore finfish sites being used up for finfish farming. The development of offshore sites or technology improvements alone hold the key for the sustained growth of the UK aquaculture industry. The offshore wind industry has been rapidly expanding in the UK and will occupy major amount of coastal offshore space when zoning plans are developed. The prospects for using the offshore wind farm areas for aquaculture production (finfish and other species) has the potential to open up new sites for finfish farming in the UK. This work examined the suitability of aquaculture in offshore wind farms from the point of view of all the stakeholders involved.

This report presents an overview and discussion of the methods and data collected during the 2017 pilot survey of employment in the UK fishing fleet, conducted by Seafish. The main purpose of the pilot survey was to test a methodology and questionnaire design for the collection of social data on the UK fishing fleet. The information presented in this report focuses on the sample collected and does not represent a complete picture of employment throughout the UK fishing fleet.

High-quality razor clams (Ensis spp.) are currently exported via airfreight to the Far East where they command a high price; there are believed to be substantial underutilised stocks around the UK.<brTo assist in the possible development of this fishery, different methods of capture and post-harvest handling of razor clams were investigated to examine the conditions of capture and storage most likely to produce and maintain high quality and viable live animals. The razors used in the study had been either diver-caught or harvested using a commercial fluidised-bed towed razor clam dredge.

Freshness is recognized as a main element of fish quality. The direct key functions of storage time and temperature have a significant influence on fish freshness. Therefore, objective assessment has been applied to find a reliable method to determine the fish freshness. Sensory methods such as Quality Index Method (QIM) or Torry assessment are commonly used; however, these techniques rely on skilled assessors and scoring can drift without regular re-training. As a result, a number of instrumental methods have been studied to evaluate fish freshness. Early studies of Nilsen et al. (2002) used a near infrared (NIR) spectroscopic technique applied to specific regions of cod fillets. In this study, imaging methods have been used to study several sections of cod to assess which have the greatest potential for discrimination of changes related to storage time. The appearance and changes in the NIR reflectance spectra of whole fish, fillets and gills during storage on ice have been measured with several instruments to assess their suitability for objective freshness evaluation. This report summarises the results of the research.

This report details work carried out on the design and installation of an engine performance test facility located at the Holman’s Test Mine, operated by the Camborne School of Mines (CSM), an academic department of the University of Exeter. The work was commissioned by the Sea Fish Industry Authority (SeaFISH) with the aim of developing a facility to permit the testing of biofuels such as biodiesel and biofuel blends in marine diesel engines. Engine performance test cells of this nature are generally configured to test various engines, whereas for this project, the engine needed to be a constant with the fuel being the variable.

Currently most of the dredge fisheries for scallops (both the great or king scallop Pecten maximus and the queen scallop Aequipecten opercularis) are unregulated by technical measures prescribing design features of the dredge. Concern about the capture of undersized scallops resulted in the Seafish Scallop Working Group recommending that technical measures be introduced in dredges targeting Pecten in order to increase size selectivity. The purpose of this study was to assess the extent to which tooth spacing, mesh size and ring size could be used to effect size selection in dredges targeting Pecten.

The aim of the study was to establish baseline conditions for the abundance and mean size of four species of interest (Pink seafans Eunicella verrucosa, dead men’s fingers Alcyonium digitatum, ross coral Pentapora fascialis and king scallop Pecten maximus) across Lyme Bay shortly after the implementation of four voluntary Marine Protected Areas (MPAs) inside which scallop dredging stopped in September 2006. The research undertaken was the initial stage of a proposed longer-term project to quantify the effectiveness of the reserves in the protection of the reef communities, to examine potential recovery rates in areas that had been exposed to scallop dredging, and to determine if there were fishery spill-over effects arising from increases in scallops within the areas protected from fishing.

The use of pure plant oil (PPO), also known as vegetable oil, as a diesel fuelextender or as a total fuel substitute is known. The concept gained popularity during the fuel crisis in the 1970’s although engine technology at this time was relatively basic. The concept today has two primary drivers for land transportation: cost reduction and environmental footprint. The use of recovered and suitably processed used cooking oil (UCO) can offer further substantial atmospheric carbon dioxide (CO2) mitigation together with a reduction in other regulated exhaust pollutants, such as sulphur dioxide, as well as additional cost savings compared to virgin PPO,.Regenatec has developed technology which retro-fits to diesel engines and allows them to be fuelled by diesel or PPO or UCO. This technology is found in products being sold to owners of land based vehicles, both commercial and domestic. Initial trial work performed by Regenatec on land based vehicles has shown promising results. This project investigated the use of PPO in a trawler, the Jubilee Quest, based in Grimsby, UK, operated on PPO during the Autumn of 2006. The aim of this trial was a technical investigation of the technology and PPO: it was not designed to be a commercial deployment. The use of PPO (and even UCO) is currently commercial unviable in UK marine applications due to the economies of scale enjoyed by the petrochemical industry. (The use of PPO and UCO is only viable for land based vehicles because of a duty rebate currently enjoyed by bio-fuels.) As biofuels start to scale and when the environmental costs of fossil fuels are fully reflected in the cost of the product, it is anticipated that biofuels will become economically viable. As a key part of this project, Regenatec developed their technology into a system to be used at sea by a trawler. Their dual tank system is under electronic control to automate the use of PPO in a diesel engine. This has significant advantages over existing, less sophisticated technology. The engine is started on conventional marine diesel (or biodiesel) and then automatically switches over to the lower cost, more environmentally friendly PPO. The automation greatly improves the ease of use for unskilled operators and removes the potential for engine damage when compared to manual control. Additionally, Regenatec is heavily involved in fuel additive work investigating what fuel additives commonly used to enhance the technical and environmental performance of mineral diesel are applicable to PPO and UCO. This work is being undertaken under Confidentiality Agreement in conjunction with a leading mainstream additive manufacturer. An ‘additive pack’ was not fully developed and therefore not available for field deployment during this project. However, lab work and land based field trials in this area have provided encouraging feedback.

Delivery Report for 2015-16

During the autumn 2006 mackerel season a prototype selectivity grid was trialled on the Zephyr LK 394 and the crew reported that both the average size of mackerel increased and the by catch percentages of herring were reduced when compared to catches by its pair trawler Antares LK 419. Following these initial observations the fishers that were involved recognized the need for independent observation and analysis of results. This led to the current project being proposed and subsequently receiving funding through the Scottish Industry Science Partnership fund (SISP).

The 2005/06 operational year at Seafish was marked by balancing delivery with planning for the future. We delivered a significant number of projects in support of our industry whilst undertaking a detailed Board and Management review of industry needs and the competencies required of Seafish as an organisation to deliver solutions.

The Future of Our Inshore Fisheries project is an ambitious, collaborative and co-created initiative aimed at addressing these issues and establishing an effective inshore fisheries management regime.

Since 2012 there is a cap on the annual number of days at sea that 15m and over scallop vessels can dredge in ICES Area 7, as part of the Western Waters Management Regime (WWMR). In response to requests by industry and government, Seafish analysed the economic performance of UK vessels that dredge for king scallops in Area 7. The analysis uses fishing activity and economic data of UK vessels that landed any amount of king scallops from Area 7 during a calendar year from 2008 to 2015.

Summary of June and October 2012 ICES advice for cod, Dover sole, haddock, hake, herring, mackerel, megrim, monkfish, nephrops, plaice, saithe and whiting. Also limited advice for brill, dab, flounder, grey gurnard, lemon sole, ling, pollack, red gurnard, striped red mullet and turbot.

Following on from a previous study to develop test criteria for defining 'free of flesh' shell, further trials have been undertaken to see whether a leach based test methodology could be used as an alternative. Additional tests were carried out on a range of different processes to identify which may be commercially feasible for producing free of flesh shell. The results of the trials showed that the leach based testing methodology was not reliable as a method. Crushing shell is an important stage in difficult to clean products such as crab. A commercial hybrid shell cleaning system could be suitable for commercial use but further engineering is required to develop a suitable system and the commercial viability will be dependant on any value of the clean shell by-products.
