Comparative Sea Trials of plastic stack-next and stack only fish boxes

Although the wooden fish box is still commonly used in Scotland for handling fish both at sea and ashore there is a growing acceptance of an eventual change from wood to plastic boxes. Of the two types of plastic box available (stack-only and stick-nest) the stack-nest is considered a most suitable replacement and is already in use ashore but there have been reservations concerning it use at sea. From June to December of 1986, Seafish carried out a series of comparative trials on Scottish vessels to assess plastic boxes when used at sea. The boxes used were a new stack-nest design, produced to a Seafish specification as a replacement for the wooden box, and an existing plastic stack-only box of the same nominal capacity of 70 litres. The trials are described and discussed in this report This report has been produced from a scanned original and may therefore contain some formatting and other inaccuracies.

Mussel purification initial trial of a medium-scale deep stack purification tank

Seafish have developed a multi-layer purification system with a partial re-use of artificial seawater in order to produce a more cost effective and controlled method of mussel purification. This plant is now operational in Kings Lynn.

Classification of Fish Species using High Resolution Sonar Techniques

This report describes the activities and results obtained from the research programme that was designed to investigate the feasibility of using high resolution sonar techniques for classifying fish species. The final aim of this work would be to provide the fishsing industry with an instrument that is capable of reliabily identifying the species of fish within the sonar beam, before they are caught within the trawl net.

A Review of the First International Conference on Molluscan Shellfish Safety

The First International Conference on Shellfish Safety was held in New South Wales, Australia on 13-17 November 1994. It followed two successful conferences on Shellfish Depuration in 1988 and 1992 in the USA and France. This report contains the abstracts of the papers, a brief summary of the presentations, the conference recommendations and some interpretation of these with regard to the UK industry. An appendix outlining some of the illness associated organisms detailed in the papers is included.

Mollusc Purification Plant - The Whitstable Oyster Fishery Company

The Whitstable Oyster Fishery Company wishes to install a small purification unit both to purify and hold native oysters for use in their seafood restaurant. They approached Seafish a year ago regarding tank design and approval procedure at the time when the Seafish vertical stack purification unit was under trial at Maldon, Essex. They considered this type of unit to be ideally suited for their application and decided to wait untilt rials were completed and the unit commercially available.

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 Fisheries of Eastern Scotland - A Regional Review

The South Eastern Region of Scotland has always had a long tradition of fishing and many communities have become dependant on the sea for a living. The depletion of North Sea stocks and the decline of local processing have caused severe difficulties in recent years.

Improved Utilisation of Fish Waste in the UK.

The fish industry developed around fishing ports when landings were plentiful and there was little concern about environmental impacts. Nowadays, natural resources and the environment are under threat and are becoming increasingly protected by law. Government policy now focuses on the protection of resources, promoting sustainable utilisation and reducing emissions to the environment. Fishing opportunities are reduced and waste generation is increasingly penalised. Concerns about farm animal diseases are resulting in the closure of some of the existing routes of waste utilisation and are adding further restrictions and costs to waste disposal. This has become a significant problem for many sectors of the fish industry and is unlikely to improve. It is essential that the fish industry minimises waste and maximises the value of all the material available to it.

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.

Mussel Spat Collection and Cultivation Trials in Wales using Bouchots 1987-89

This report describes an investigation into the viability of using the French bouchot pole and Italian pergolai net stocking method for cultivating mussels in South Wales. A modified trial was established in North Wales to accommodate reduced tidal ?. Seed was collected from Morecambe Bay and Caemarfon and monitored over a two year growing period. A computer program was developed to compare growth performance at each site. After a T. Wrayo year growing cycle the mussels averaged 47 mm; 38% meat yield and trade opinion indicated a minimum price of 450/tonne. Costings suggest that for an investment of 20,000 a return of 45,000 per annum is projected.
