Conversion of Side Trawlers to Double Beam Trawlers

British United Trawlers (BUT) Grimsby have requested the Industrial Development Unit, White fish Authority, to conduct a preliminary study into the feasibility of converting a number of their existing middle water side trawlers, which are laid up at present, to double beam trawl operation for high value flat fish. It was suggested the ‘ROSS JUNO’ should be used as the basis ship for the purpose of this study. The results, however, are applicable in general to other similar vessels in the BUT fleet. The most important consideration in the conversion of a side trawler to beam trawling is the effect of the external loads on stability of the vessel. These loads which in themselves may be small are applied at a large distance from the vessels centre of gravity and can result in large applied moments of force.

Further Acceptability Trials with Farmed Turbot

Following on from the acceptability work carried out in London during the summer of 1974, further trials with farmed turbot from the Authority’s Marine Fish Cultivation Unit at Hunterston in Ayrshire, were conducted in different sections of the fish retail trade including wet fish wholesalers, a frozen fish processor and distributor, fishmongers, restaurants and hotels.

Testing of Fish Recipes to be Incorporated into a New Recipe Book for Use in the School Meal Service

The purpose of the investigation was to test the suitability of several recipes for inclusion in a recipe book for school meals. Suitability was measured in terms of plate waste, popularity with children, cost and ease of preparation. The results showed that the more adventurous recipes were more popular with the children than the rather bland traditional fish dishes, and these dishes were also preferred by the kitchen staff. However, it was felt that all the recipes which had been developed showed sufficient potential for inclusion in the recipe book.

Scallop Overgrowing Depth Trial 1979/1982

The scallops. Pecten maximus (L) and Chlamys opercularis (L) were on grown at four levels in the water column to establish the optimum depth for growth and meat yield. This report gives final data for trials set up using spat collected in 1978. There appeared to be no depth related mortality pattern after the initial stages of cultivation. For optimum growth and meat yield, it is suggested that Pecten should be maintained below 4.5m initially, and then brought nearer the surface as they increase in size. Chlamys can be grown at shallower depths throughout the culture process, but the increase in growth and meat yield was not as great.

Interviews with Fish Friers Selling Blue Whiting & Customers

This report, prepared on behalf of the White Fish Authority (WFA) by David Elliott & Associates, describes the reactions of five fish friers in Wigan, Peterborough and Chatteris (Cambridgeshire), and their customers to block filleted blue whiting. It is the third report covering interviews held with fish friers selling blue whiting, and their customers. The first two reports, issued as TR 137 and TR 146 in 1976, dealt with a situation where frozen block filleted blue whiting was supplied to members of the Executive Council of the National Federation of Fish Friers who had volunteered to sell the fish on the WFA’s behalf. Since these reports were issued, the WFA have continued to sell blue whiting on a low key, but regular and fully commercial basis to a number of outlets – some 30 friers have now tried the fish.

Collection and Sorting of Scallop Spat 1983

Scallop spat collection was carried out in Loch Ceann Traigh in the summer of 1983. The peak settlement of both Pecten and Chlamys occurred in mid-July. The report details collection and sorting procedures and data on the performance of different types of collector.

Hall Test Research of Blue Whiting (1976 Catch)

A second series of Hall Tests were held in a further 3 locations (Bristol, Glasgow, Manchester) in July 1976 using Blue Whiting from the Hebridean and Shemara catches of spring 1976. Because the fish were landed chilled, the resulting fillets were considered to be of sufficient quality to allow them to be displayed raw. For each Hall Test approximately 200 housewives were shown raw fillets and then tasted two samples – one crumbed and pan fried, the other grilled. The order of presentation was rotated, and responses to the appearance (cooked and raw), flavour, texture, and colour were recorded.

Summary of Market Research Carried out to Determine the Market Potential & Market Opportunities for Fresh Mackerel in the UK

Rapid increases in mackerel landings during the last 3 years – to a point approaching 10% of the total UK catch – have not been matched by corresponding growth in the home market, with the result that this protein rich species is seriously under-utilised in terms of human consumption in the UK. As part of an on-going programme to discover the market potential and market opportunities for mackerel the Market Development Unit of the White Fish Authority (WFA) contracted the services of marketing and advertising consultants, David Elliott & Associates, to conduct research into housewives’ attitudes towards mackerel and ways in which it was used.

Comparison of Results in Dover Sole Research and Development to November 1978 with Previous Performance Forecasts 1975 & 1977

This report has been written to present in abbreviated form the progress made with the fish hatched in 1977 and 1978. About a quarter of the 1977 stock has exceeded the minimum size (250g) at which maximum market unit price is achieved; the majority of the remainder should achieve harvest weight at an age of 22 months. The 1978 stock, some are now nine months old, due to successful early spawning by photoperiod control, are growing more strongly.

Measurement of Cod End Handling Loads on 65-85m Stern Trawlers Engaged in Mackerel Handling

Load measuring trials on the CORDELLA, a 70m stern trawler, took place during the 1979 – 80 mackerel fishing season. During the 6 day fishing operation, 10 hauls were made with a valid fishing time of 12 hours resulting in a total estimated catch of 294 ton. The maximum, recorded loads taken of both cod end inhauling and cod end tipping are 43 ton and 24 ton respectively. These loads together with the loads obtained on stern trawlers in the 35 – 45 m length range will help to advise the UK Mutual Insurance Co. of revised standards of working gear for these classes of vessel.

Mackerel Research - Omnibus survey of housewives 1976 1977 and 1978

For the past three years, as part of its on-going programme of research into consumer and trade attitudes towards mackerel, the White Fish Authority has been commissioning quantitative research in the form of annual omnibus surveys in order to determine current usage of the species. The surveys were conducted in July 1976, September 1977 and September 1978. This report deals with the third of these surveys, and its findings are compared with the findings obtained in the two previous years. The information in the report has been summarised to the extent that certain tables have been omitted, but all the research information is available from the White fish Authority should it be required.
