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.

SR684 Case study: consumer messages concerning brown crab products in selected European market

This case is an in-depth review of brown crab products as seen from a consumer perspective. The case 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. Topics covered include ethics of production (animal welfare - clawing, harvesting, storage and slaughter); food safety (biotoxins and cadmium); labelling; and stocks .

Basic Fishing Methods

A comprehensive guide to commercial fishing methods. This publication contains illustrations and descriptions of commonly used fishing methods, gears and rigs.

Options for improving fuel efficiency in the UK fishing fleet - key features

The key features leaflet contains a summary of the full report. Our intent in providing this summary is to clearly illustrate practical options to improve fuel efficiency to UK vessel owners and skippers. By providing this information we hope to encourage fuel efficient practices and provide guidance on evaluating investment in new equipment needed to adopt new practices, thereby enhancing the profitability of vessel business.

Economics of the UK Fishing Fleet 2019

The report presents economic estimates at UK, home nation and fleet segment level for the UK fishing fleet. The estimates are calculated based on samples of fishing costs and earnings gathered by Seafish as part of the 2019 Annual Fleet Economic Survey

A Business Study of the N. Ireland Fish Industry

This study, carried out in 1982/83, describes the fisheries of the County Down coast centred on the three ports of Kilkeel, Portagovie and Ardglass. The costs and earnings of fishing vessels are given and the report points out that the catching capacity of the Northern Ireland fleet is in excess of the resources available to it and alternative opportunities must be sought. Included are assessments of the Northern Ireland consumer market. This report has been produced from a scanned original and may therefore contain some formatting and other inaccuracies. In cases where this affects the technical content, a paper copy of the original report can still be obtained from Seafish.

Electrofishing in Marine Fisheries

This Information sheet describes and discusses the environmental effects and fishery management implications of marine electro fishing with particular reference to pulse trawling for flatfish, hovercran fishing for brown shrimp and fishing for razorclams.

The introduction of Quad rig in the NPF – seeking an effort neutral transition and implications for TED/BRD performance

Since 1987 the Northern Prawn Fishery (NPF) fleet has towed double rigs (two nets). Prior to this most trawlers towed quad rig (four nets). To improve economic efficiency in the fishery there is great interest to again allow the use of quad rig.
