Site Visit to Inspect Oyster Depuration Tanks at la Rocque Fisheries Ltd
La Rocque Fisheries Ltd on the island of Jersey have installed three purification tanks to depurate Pacific Oysters (Crassostrea gigas) taken from their nearby oyster growing lays. The tanks, which had been built to a French design, require approval from the States of Jersey Department of Agriculture and Fisheries. Seafish were asked by La Rocque to make a site inspection and given an opinion on the suitablity of the tanks for depurating Pacific and Native (Ostrea edulis) Oysters. Peter Wilson, Senior Fish Technologist Engineer at Seafish visited on 15 April 1998. -
Static Fishing Nets - Experiments to reduce unwanted bycatch and bottom debris
In August 1987, Seafish carried out sea trials to assess the efficiency of trammel nets constructed of a number of alternative materials IR1341 refers. One of the main objectives of the work was to assess the effectiveness of monofilament nylon used in the construction of trammel nets with the aim of reducing net clearing time by making it more easy to remove crabs and bottom debris. -
Improving the post harvest care of small shrimp
Initial investigations have shown that it is possible for shrimp cooked at sea to meet the temperature requirements of both the Food Hygiene (Amendment) Regulations for cooked products and E.C. Fishery Products Directive, which willcome into force in January 1993. This is by the use of direct and indirect icing and insulated fish boxes to hold the cooked shrimp, on board vessel. Icing the cooked shrimp at sea also significantly extends the subsequent storage life of the product. It has also been shown possible to hold uncooked brown shrimp in ice onboard and then transfer the cooking operation ashore and produce a satisfactory product. However, during these initial trials this practice was not found to be satisfactory with pink shrimp. -
The Highland Region. The Prospects for Fisheries and Aquaculture in the 1990's
Part of the Highland Regional Council's structural policy is to make the best use of its natural and human resources. This includes investments in both fishing and aquaculture as well as encouraging development of these industries through the provisions in its Structure Plan 1990-99. Previously the White Fish Authority prepared an advisory paper for the Council in 1980 entitled 'The Fisheries in the Highland Region - A study in conservation and development. -
A summary of the Illness Associated Organisms which can affect Molluscan Shellfish Safety
This report describes the main causative agents and the testing and control measures routinely adopted to protect the public. This report was originally written as an appendix to a report on the first International Converence on Molluscan Shellfish Safety, to provide background information on the illnesses discussed during the conference. This conference, at which Seafish presented a paper on some of their recent work on Mollusc Depuration, was held in November 1994 at the University of New South Wales, Sydeney, New South Wales, Australia. -
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. -
Selectivity Trials using Square Mesh Panels in a Scottish Seine
This report is part of a continuing series of sea trials examining different methods of fish capture in an attempt to improve and standardise the design and position of square mesh panels or windows within the trawl to reduce the levels of discards whilst retaining acceptable proportions of marketable fish. On these trials double panels were tested in a Scottish seine net in order to decide on the preferred position for further trials. -
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. -
Squid Jigging Trials Aboard FRV G A Reay
Squid fishing trials involving the use of bottom and midwater trawls, and hand and automatic jigging techniques with light attraction were conducted at various locations between the north east coast of Scotland and the Faroe Islands during September/October 1983. -
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. This report has been produced from a scanned original produced in April 1977 and may therefore contain some formatting and other inaccuracies.

Squid Fishing Trials Aboard MFV Joker in Cornwall
A small Cornish inshore vessel has been rigged with gas lamps and jigging equipment for catching squid. Unfavourable weather conditions prevented a proper assessment of the equipment during the Author's visit, however, a report is expected from the fishermen in due course. This report describes the installation and includes background information. 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. -
Proceedings of the Humber Waste Seminar, 12 June 1997
These are the papers submitted at the Seafish Humber Waste Seminar, held at TC's club in Grimsby on 12 June 1997. Recommendations and findings are based on surveys carried out at a number of fish processing companies in the Humberside region. This collection of papers aims to provide an introduction to relevant waste issues and highlights some areas where waste minimisation can be put into practice. 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.
