Study to forecast the commercial cost of farming plaice

Much of the Authority’s early work in rearing marine fish was concentrated on plaice, however as the trials data accumulated over the late 60’s and early 70’s, it became apparent that, despite its suitability as a farm animal, the plaice could not under the market conditions prevailing recover its costs of production. This was demonstrated by a joint study with the Central Electricity Generating Board (ref 1) using 1971 data, which concluded that the estimated production cost of farmed plaice per ton, would be nine times the then value per ton of current trawler landings.

Trawl Door Trials on Board Fishing Vessel 'Clupea'

This report documents the work carried out on Trawl Door research during a voyage on the D>A>F>S> vessel CLUPEA, the testing being directly relevant to the programme of model testing in the Seafish Flume Tank. The trawl doors under test were steel vee doors in three different sizes in use with the same net. It was intended that flat doors were to be similarly tested but this part of the programme was severely curtailed by weather and instrumentation factors.

Findings of a Basic Water & Effluent Survey Carried Out at French Fish Limited

As part of the North East Scotland Strtegic Study, Seafish has been involved in briefly visiting representative companies in the region to survey water use and effluent production. The purpose of these visits is to estimate the general reductions in both water use and effluent strength which could be made by introducing waste minimisation. This report summarises the findings of the brief visit to French Fish Limited carried out on 5 May 1999.

Cardigan Bay Fisheries Development Phase 2 Report - Summary of Findings

Mid Wales Development request that Seafish undertake a study of the 100 mile section of Cardigan Bay for which they have responsibility for economic development to see if action could be taken to stimulate new jobs and income from fishing and fishing related activities. This study discusses the commercial fisheries, sea angling, shellfish and fish farming and marketing of fish, and this report contains the findings of these individual sector studies. A further study on an aquarium – visitor centre for Aberystwyth is in course of preparation. The sector studies are covered in separate reports listed at the end of this document.

Opportunities in the UK Crab Fisheries Resources - Process Technology - Markets - New Products

The study covers the current and projected crab resource picture in the UK and the trends in new mechanical flesh recovery equipment. It also discusses the market opportunities and sets out the details of 9 novel crab products developed and tested under a contract with Youngs Sea Foods This report has been produced from a scanned original and may therefore contain some formatting and other inaccuracies.

An Analysis of Fish Quality & Temperature Data from a Survey of UK Ports

This report, prepared as supplementary information for an MSc thesis describes the methodology used for the 1985 SFIA Port quality survey, presents a model of quality change at varying temperatures, analyses the survey data for the effects of the various handling practices in use aboard vessels and at the ports, and presents an estimate of the UK distribution of the quality of fish at first sale (see also IR 1294).

Lyme Bay plaice sampling trip 13-14 March 1999

According to local sources the Lyme Bay area usually supports a plaice (Pleuronectes platessa)fishery through the month of April, exploited by beamers working from Brixham. During the first quarter of this year however, vessels reported significantly larger catches from mid-February through to early March. Following approaches by the SWFPO, CEFAS arranged with Sea Fish for a Discard Officer (DO) to carry out a sampling trip to examine the current plaice catch in the Lyme Bay area.

The Brown Crab Fishery in the Western Isles Prospects for Development

The Western Isles crab fishery has some scope for increased production but more importantly there is scope to increase the value of the fishery to the Western Isles economy. However, there are some significant barriers to development which need to be addressed. Firstly the local creeling fleet has expanded considerably in the last 10 years and now stands at 160 full-time boats almost all under 10m in length and many are now ageing. As a consequence of size and age, these boats are confined to inshore waters, within a few miles of their home port or landing and this results in excessive effort in certain areas and little or none elsewhere. These vessels are unable to provide any significant fishing effort on the Atlantic side of the Isles and thus exploitation of this resource is denied to them.

Fleet Management Policy Appraisal Model: Biological Feedback Phase

The Fleet Management Policy Appraisal Model is under development as a computer model to make comparative assessments of management policy scenarios over a seven year predictive period. The biological feedback phase assesses the effects of each year's catches on the stocks of each species, and the consequent effect on catch rates in successive years.

Relationships between Fish Supplies and Processing Capacity in the UK

This paper analyses the pattern of fish supplies in relation to the existing processing capacity and its location and to the main areas of consumption. See Report 276.

An Investigation into the Landings, Value and Storage Properties of Ungutted White Fish

This paper summarises the work into one aspect or quality control at sea, namely the practices of gutting or not gutting. The investigation has considered previous research into the subject and carried out further research to support earlier findings and to close some of the gaps. It will be stressed throughout this work that of paramount importance in quality control at sea is the need to transfer the catch as speedily as possible into melting ice in order to reduce the temperature. All other considerations including gutting become of second order importance if this one action is taken properly.
