De-infestation of slipper limpets from mussel seed

The mussel culture industry is one of the largest and most valuable fisheries in the UK representing almost 90% of total shellfish aquaculture production by weight in England and Wales with a value of around £14 million per year. Continuing productivity is significantly dependant on the movement of mussel seed from wild settlement areas to cultivation areas. Unfortunately, these shellfish movements can also spread pests such as the non-native slipper limpet (Crepidula fornicata) which has the potential to have a devastating effect on both fisheries and marine eco-systems as it out-competes other species for food and space as well as depositing pseudo-faeces that builds up to create cohesive ‘muds’. An accidental introduction of slipper limpets into the major UK mussel culture area of the Menai Straits, North Wales has recently occurred following a movement of mussel seed contaminated with slipper limpets from the English Channel. This led to urgent remedial action having to be taken by industry which involved removing the infested mussel seed and then smothering of any remaining slipper limpets with new slipper limpet free seed. There is a need therefore for the industry to self regulate and minimise risks in such transfers. Failure to do so will otherwise result in measures being imposed on industry in this respect. Positive action is now currently being undertaken in some regions as can be seen by the development of a Code of Good Practise by the Bangor Mussel Producers.

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.

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.

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.

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.

Project Inshore Stage 2 report

SR682 Opportunities for brown crab processed products in selected European markets - trade perspectives.

This research is an in-depth review of brown crab processed products as seen from a trade perspective. The research is produced as a specific output of the wider Acrunet Activity 5 which seeks to understand the wider system of brown crab practices from production to consumption within the EU.

An Assessment of the Impact of Selected Fishing Activities on European Marine Sites and a Review of Mitigation Measures

The report summarised here has been commissioned by the Sea Fish Industry Authority (SEAFISH) with the aim of determining the potential impact of fisheries on EMS interest features and site integrity in relation to their conservation objectives.

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.
