Inland Wholesale Fish Markets - 2. The Retail Survey

This is the second of three reports which make up the Joint Study of the inland wholesale markets in Britain. The first report described the situation at the inland markets as seen by wholesale merchants themselves. The present volume examines the inland markets from their customers’ point of view. It is based almost exclusively upon an analysis of nearly 400 questionnaires completed by fishmongers, general food retailers and fish friers and it is intended to reflect their opinions as closely as possible. 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.

The Effect of Soak Time on the Quality of Cod in Set Nets

The quality of cod resulting from net immersion periods (soak times) of between 3 and 48 hours was investigated. The trials were carried out on a 9 m boat along the Yorkshire coast during July and September 1991. The fish which were alive when brought on board were in excellent condition. After 9 hours soak the freshness of the cod progressively reduced as the physical damage increased. Over half the cod from the 48 hour soak time were spoiled beyond marketability. Recommendations to help assure quality are made.

A Guide to the Manufacture of Marinaded Products

The pelagic resources of the UK are valued at about £70m. Of this, about 60% are disposed of as whole fish or chilled fillet form. Only abut 20% are sold in some form of added value product and of these about 1% are marinaded. There are opportunities to increase sales of herring particularly by marinading and this report reviews the process by which marinades are made, the raw material specification and the packaging techniques.

Cockle Dredging/Improve Performance Using a Solids Pump

This report describes the development of an improved cockle dredging system for the small (about 12 metres) vessels in the UK fleet carried out under MAFF R&D Commission 1988/89, Project Code IAG16. The major change was to use a solids handling pump for pumping water and cockles from the dredge head as opposed to the former method of a water jet pump incorporated within the dredge, which was the principle of the WFA cockle dredge developed in the 1960’s. Four different solids pumps were shore tested and three found to give satisfactory performance running at a restricted speed. The dredge head design was altered to resemble a smaller version of the standard Dutch suction dredge which has incorporated the solids pump principle for some years. The Dutch dredgers, however, are much larger than those in the UK and for this reason it was not possible to transfer the technology from one fishery to the other. Two separate shipboard installations were completed at Kings Lynn and subsequent trials in the Wash were most successful.

The Importance of Klondyking to the U.K. Pelagic Fishery

Klondyking accounts for the bulk disposal of pelagic catches of herring and mackerel. Should the Klondyke fleet fail to come each year there would be no immediate means of disposing of the catch. The fleet also provides invisible earnings to the Highland region in the form of expenditure by crew and in supplies. The report examines these factors.

Norfish: Nordic Fish Supplies in the Context of International Trade

The 1990s are a period of massive changes in fish supplies especially into the European Community. The Community as a whole is the largest single importing block in the World but there is keen international competition to secure supplies in the future. A major source of supply for EC and the UK in particular are the Nordic countries with whom traditional links have been long in place. The report explores these in the context of the changing situation. This report has been produced from a scanned original and may therefore contain some formatting and other inaccuracies.

Findings of a Basic Water & Effluent Survey Carried Out at D. Couper Ltd

As part of the North East Scotland Strategic 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 D. Couper Limited carried out on 27 April 1999.

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.

Fleet Structures Model - Overview and its Use in Decision Support

The Fleet Structures Model (FSM) is a predictive model with the purpose of simulating aspects of the structural development and operation of a national sea fishing fleet in order to make comparative assessments of fleet management policy scenarios.

Scallop Predation by Crabs, in Relation to the Development of On-Bottom Cultivation

The feeding success of four species of crabs (Crustacea : Brachyura) which are potential predators of the scallop Pecten maximum (L) was studied under laboratory conditions. Liocarcinus depurator was the only species not to prey on scallops of 4 and 5 cm shell height, whereas Liocarcinus puber. Carcinus maenas and Cancer pagurus showed the greatest potential to prey on scallops and further experiments were carried out with this species using a wide size range of bivalve. Presented with scallops within the range 3-9 cm shell height resulted in the following trends : as prey size increased, the proportion of crabs feeding decreased, male and female crabs showed similar predatory behaviour, and marine fouling on scallop shells had no significant effect on crab feeding. These findings are discussed in relation to the potential for bottom culture of P. maximus.

Trials to Investigate the Effect of Onboard Hopper & Conveyor Systems on Fish Quality

With concern that the deep fish reception hoppers and associted elevators for mechanised handling of the catch on whitefish vessels could be affecting fish quality two sea trips were carried out on Scottish seners/trawlers during September 1997 to take fish samples for assessment at processing.
