Pilot Trials to determine the benefits of high pressure processing (HPP) for seafood in the UK: Phase 1 Report

High pressure processing studies were carried out on 11 species of fish and shellfish in order to determine whether there were any potential processing benefits for the UK seafood processing industry. The species tested were: Nephrops norvegicus, mussels, oysters, crab, cold water prawns, lobster, warm water prawns, unsmoked salmon, squid, mackerel and cod. In each case, a 20-run experimental design was employed and six of the 20 runs (from a single design block) were evaluated for sensory quality compared with a control sample. After processing, all 20 runs were evaluated for survival of TVCs, coliforms and pseudomonads. In some products, measurements of yield were carried out to determine whether HPP offered any processing benefits, e.g. for peeling, picking or shucking of seafood.

Use of waste as a biofuel and fertiliser in Orkney_C008

Shellfish processors want simple, local, cost-effective solutions for managing shellfish waste. Anaerobic digestion (AD) has been identified as a potential solution for shellfish waste treatment. The process produces methane which can be used to generate energy and digestate (fertiliser) which has applications in agriculture and horticulture. Heat and Power Ltd. were part funded by Seafish to evaluate the potential of AD as a solution for Orkney based shellfish and food processors. The main aims of the project were to consider whether AD could reduce commercial waste disposal costs and establish a sustainable waste management solution for the island. It included a small-scale batch digester trial on crab shells. This report summarises AD technology, suitable food wastes in Orkney and results of a small-scale batch trial on crab processing waste.

Development of a suitable dredge for exploitation of razorfish (Ensis directus) in The Wash

This report describes a study of the environmental effects of razorfish dredging within a SAC (Special Area of Conservation) under the Habitats directive. The study includes instrumentation, environmental modeling and was used as an appropriate assessment under for the experimental fishery for this species in The Wash.

Fleet Economic Data 2005-2014

The Seafish fleet economic performance dataset in PDF format. This dataset contains financial, economic and operational performance indicators for the period 2005-2014. The dataset covers approximately 30 UK fleet segments, and has been produced by combining costs and earnings information collected from vessel financial accounts contributed to the annual Seafish UK Fleet Survey by vessel owners. Data on official effort, landings and capacity data was provided by the UK Marine Management Organisation (MMO). 2014 estimates are based on provisional official data for 2014, 2014 fuel prices and 2013 cost structure derived from 2013 vessel accounts submitted to Seafish.

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.

Fishermen's Environmental Monitoring Pilot - Exploring the Role of Fishermen in MPA and Environmental Monitoring

The evidence and data requirements for the designation and subsequent monitoring of MPAs place significant logistical and economic burden for official bodies. This report demonstrates how the fishing industry can play an integral role in marine monitoring and evidence collection using underwater video surveys as a model. Collaborative surveys are shown to have mutual benefits in terms of cost and efficiency savings, knowledge transfer and relationship building.

Project Inshore - Stage 3 Strategic Sustainability Northumberland Inshore Fisheries & Conervation Authority

This report presents stage 3 of Project Inshore where findings of stage 1’s data gathering on fisheries within each IFCA and the results of stage 2’s MSC pre-assessment conducted for fisheries around England’s coast (involving over 400 different species, stock and gear combinations) are considered to provide a Strategic Sustainability Review tailored to the Northumberland IFCA.

Review of the application of the Official Control Regulations for shellfish

The Shellfish Stakeholder Working Group (SSWG) commissioned Seafish to undertake a review of the application of the Official Control Regulations that apply to live bivalve production in EU Member States, with a focus on the microbial requirements.

Guidelines for the Landing and Sale of Fishery Products

Advice on how to maintain high standards of fish quality and food safety and on maximising value through efficient landing and sale operations. The guidelines cover buildings and other structures, equipment, operating practices and the management and control of operations from landing of fish, to its despatch from the market or place of landing. They apply to the landing of fresh fish, both demersal and pelagic. They do not cover shellfish, that will be the subject of separate guidelines. Whilst these guidelines contain helpful technical information some of the legislative content may now be out of date.

English Shellfish Industry Development Strategy_Securing the industry's future

This Strategy for the Development of the Shellfish Industry in England (SIDS)considers what support is needed for the sustainable and profitable development of the sector. The sustainable development of the industry, through the long term management of stocks and supporting ecosystems from the socio-economic and environmental perspectives, is paramount to delivering the Strategy. Comments were gathered from a wide range of stakeholders, including from within the industry, to help formulate the text of the Strategy.

2007 Economic Survey of the UK Fishing Fleet

The 2007 report on the economic performance of the UK fleet continues an annual series of analyses of fleet performance. This report presents detailed analysis of 36 segments of the UK fishing fleet, drawing on a combination of data collected by survey and data on landings and days at sea provided by the Marine Fisheries Agency (MFA), which covers every active vessel in the UK fleet. Every vessel active in 2007 has been allocated into one of these 36 segments. Refinements to the segmentation of under 10m vessels provides more useful average performance figures than in previous reports.
