Hall Test Research on Blue Whiting

A series of Hall Tests were held in 3 locations (Greater London, Leeds and Walsall) in February/March 1976 using Blue Whiting caught by the MAFF freezer trawler Artic Privateer in 1975. Although it was an exploratory voyage, the fish were caught under commercial conditions and did not represent the pride of an outstanding catch. The fish reflected simply the best quality obtainable from an average catch at that time of the year. For each Hall Test approximately 200 housewives were served samples of hand filleted Blue Whiting crumbed and pan fried and grilled the order of presentation was rotated, and responses to the appearance, flavour and texture of the fish were recorded.

Design Characteristics of Middle Water Trawlers: Study of Machinery Requirements

This is the first in a series of reports on the Authority's study of design requirements for future middle water trawlers. This report describes the studies made and conclusions reached on the current and future vessels in the class.

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.

Double Rig Trawl Fishing for Nephrops Norvegicus

Initial trials with double rigged gear on a SW beam trawler in 1982 had demonstrated the feasibility of working this rig in UK waters. In 1983 trial fishing was carried out successfully on Celtic Sea nephrops (prawn) stocks. Increased catch rates in comparison with single trawl rigs were recorded and gear handling was further refined. Problems highlighted included the shorting effort required with increased catches of prawn and limited market in the SW.

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.

Ambient Seafood in Multiple Retail (2023)

Ambient remains in decline but compared to 2016, ambient seafood has attracted older and significantly more affluent ABC1 shoppers; perhaps driven by the recent demand for premium imported tinned seafood

Degritting of King Scallops

Dredged scallops are known to contain ‘grit’ in the form of sand, silt, mud or broken shell. Although washed out in processing, this contamination limits the marketability of these scallops as a ‘live’ product and detracts from their value in comparison with scallops landed by divers. The initial part of this work has confirmed the considerable extent of grit contamination of commercially harvested scallops and that it is effectively removed in the production of a processed product by shucking and washing the meat, but it has also shown that the eating quality of ‘gritty’ scallops deteriorates rapidly if held unprocessed in the shell.

A Report on the UK Herring Fisheries in the 1980s

The British herring fishery has declined dramatically since the early part of the century. The ban in 1977 was a result of indiscriminate overfishing by all fishing nations in the post war period. Now that the ban has been eased, the Common Fisheries Policy sets out the UK quota clearly and in this there are opportunities for development of a more stable UK herring fishery.

Market Test of a Range of Pacific Oyster Products

Six frozen Pacific oyster products, the most promising of those developed in earlier White Fish Authority trials, were test marketed in two stages in 1974 and 1975 under the brand name, Oyster Bay. It was unfortunate that the timing of the campaign, although logical in the progression of the project, coincided with the onset and early stages of the economic depression, as one of the main reasons put forward for lack of interest by the caterers was that of price. Perhaps the major reason for the disappointing level of acceptability, however, was the overall lack of familiarity with cooked oyster products although it was encouraging to note the response to the products when this was overcome. It was also encouraging to record that fresh oysters in the shell are regarded favourably and until the quantity of UK-grown Pacific oysters increase substantially to bring production costs down in order that the processed products become economically viable, the White Fish Authority recommend that growers concentrate their efforts into stimulating demand for Pacific oysters sold in the shell in local restaurants and hotel, particularly during the holiday season.

Blue Whiting Processing Trials at Stornaway, Spring 1976 (draft only)

This report describes blue whiting processing trials carried out at Stornoway in the Outer Hebrides in the Spring of 1976. The exercise was a joint project between the Highland and Islands Development Board, Torry Research Station, and the White Fish Authority. The main objective was to test the feasibility of landing blue whiting in fresh condition at a port close to the fishing grounds, processing it for human consumption and supply processors and friers with frozen fillets for trial work and marketing.

Trials with Monofilament Longline Gear

A Cornish cove boat of 6m length was fitted out with 10 Norwegian monofilament lines, a liner hauler and shooting chute. Trials carried out on 19 fishing days allowed the crew to gain expertise in the working of this gear. Further trials are recommended to enable the baiting crew to gain experience and to confirm the catch potential of monofilament lines compared with thicker lines.

Scale Modelling of Trawl Gear

The relationship between model and full scale results for underwater flexible structures such as nets is far less well understood than for surface vessels. For the latter the empirical formulae developed over many years enable the full scale performance of a vessel to be predicted with a very high level of confidence. Recent work at the SFIA Flume Tank in Hull is promoting a greater understanding of theory for model trawls by comparison with full scale sea trials. This report, as well as describing the basic modelling theory involved, describes the trials work by reference to the performance of two full scale trawls.

Commercial Development of Marine Fish Farming - Turbot

Improvements in the controlled hatching of plaice by the Ministry of Agriculture, Fisheries and Food (MAFF), in 1963, provided the opportunity to launch the WFA fish farming R & D programme. Initially work was conducted with plaice (Pleuronectes platessa) at Port Erin, Isle of Man, jointly between MAFF and WFA (Ref 1). A survey of other marine fish likely to become candidates for farming is given in (Ref 2). By the early 70’s it was apparent that plaice farming, although technically feasible, could not be undertaken economically. Therefore since 1970, trials have concentrated on two of the most highly valued species.

Report of an Investigation into the Design and Stability Characteristics of Bute Slipdocks Vessel No. 485

The Chief Marine Surveyor (Scotland) of the White Fish Authority approached the Industrial Development Unit, on behalf of the Caley Fisheries Ltd., and Mr Peter Strachan, to carry out an independent investigation into the design and general stability standards of the vessel being built at the Bute Slip Dock under their yard number 485. This action was the result of the loss at sea of the MFV Trident which was built by Bute Slip Dock and which was of a similar design and style to yard No. 485, although it was understood that there were significant differences in hull form between the two vessels.

An Analysis of the Hull Fish Industry in 1983

The report defines the state of the Hull Fish Industry in early 1983 showing little prospects exist for the catching sector but that the processing sector remains buoyant by its dependence on fish from all over the UK as well as imports. A geographical analysis shows that Hull and Humberside have all the locational advantages of retaining their position as the most important processing centre in Europe.

Introduction of the Marine Laboratory Designed 4 Panel Bottom Trawl to the British Distant Water and Inshore Fishing Industries

Detailed studies of the design, construction and performance of traditional trawls and experiments investigating those factors controlling the geometry of trawls have been made by the staff of the Marine Laboratory, Aberdeen. Techniques allowing observation of the behaviour of fish in these fishing gears have been developed and consequent understanding of the way in which fish are caught has grown over a similar period. The knowledge accumulated from these studies has been applied during the last three years to the development of a family of 4 panel trawls. The aims of this development have been to produce a practical fishing gear having the same or preferably a higher catching power than the traditional trawls but with greater mechanical efficiency and ease of handling.

The Comparison of Continuous and Discontinuous Feeding on the Growth of Hatchery Reared Spat of the Pacific Oyster (Crassostrea gigas)

Six series of trials were held to investigate the effect on growth rate and survival of pacific oyster spat over a five week period when fed under different regimes. It was concluded that there was no effect on mortality but a significant (30%), improvement in growth rate for the same total food consumption, or reduction in food consumption for the same growth. This could be worth £2,500 per annum to a commercial hatchery. This report has been produced from a scanned original and may therefore contain some formatting and other inaccuracies.

Investigation into Potential Fuel Savings by Using Auxiliary Sail on Existing Fishing Vessels

The rising cost of fuel which has amounted to almost 700% in the last decade has resulted in a revival of interest in sail power as a means of fishing boat propulsion. This study examines the theory of sail power and its relevance to the modern fishing vessel especially the trawler or trawler/seiner of under 24m in length. The high standards of stability now required for fishing vessels coupled with the hull form developments which have taken place since the advent of the diesel engine preclude the application of sail power to existing vessels. The study develops the formulae for the sail area which can be carried by the modern vessel whilst still remaining within the IMCO criteria and this is so negligible to be not worth the structural changes and expense.

Mobile Fish Retailing

With the number of mobile retailers increasing during the past decade, this project involving the operation of such a unit, was aimed at defining the parameters of van design in relation to different types of market served. This report gives the information obtained, of the necessary and desirable features in the specification of a van designed to offer good quality fish for sale at the right temperature and in hygienic conditions. The sales information gained from the different sites used was less extensive than hoped, mainly due to the need to avoid situations in which the trials might inadvertently compete with the existing trade.

Scallop Industry in Japan

The scallop industry in Japan is the most valuable shellfish culture industry at around 34 billion yen production (£68 million). It is second to the oyster industry in terms of production tonnage at 150,000 tons/year as compared to 220,000 tons for the oyster industry. Values of scallop meats remain steady at around £560/ton for in shell and £1,400 ton for shucked meats. The rise in this industry represents one of the most successful examples of the revival and utilisation of a natural marine resource. The scallop under going cultivation in Japan is Patinopecten vessoensis (Jay), “hotategai”, basically a cold water shellfish whose southern limit of distribution is about 35 degrees latitude on the Pacific and Japan sea coast. The main cultivation areas however, are to be found in the north of Honshu and in Hokkaido. This discussion centres on 3 cultivation areas, which in terms of production tonnage are probably the most important scallop growing areas in Japan. These are Mutsu Bay in Komori Prefecture, Funka Bay in S E Hokkaido and Lake Saroma in the north of Hokkaido with the adjoining Okhotak Sea coast. The scallop cultivation technique depends on the relatively simple concept of collecting newly settled stages of the shelled larvae (called ‘spat’) and on growing or raising these juveniles in a protected, maintained environment until they are of a commercial size and can be marketed. Scallop cultivation is one of the relatively new culture processes in Japan with commercially significant tonnages of cultured scallop being produced only in this decade. However, the collection of settled scallop spat on ‘collectors’ and the subsequent sowing of selected juveniles in seabed areas are favourable for their growth, goes back to the 1930’s.

Trials of the ABCO Pneumatic Discharger at Fleetwood

Following the voluntary liquidation of Fleetwood Fishing Vessel owners Association, two new companies, Fish Handling (Fleetwood) Co. Ltd., and Fish Ancillary Equipment Co. Ltd., have been set up to discharge the fishing vessels at Fleetwood. The port has been made more competitive by an agreement with the Dockers union, the TGWU, to cut manning levels and introduce mechanisation. With the assistance of the White Fish Authority the first of a new model ABCO pneumatic discharger has been supplied by its Canadian manufacturers, the Atlantic Bridge Co. Ltd., and the Authority has supervised commercial trials of the discharger at Fleetwood. The trials have compared the performance of the ABCO discharger with the more traditional methods of unloading bulked and boxed fish.

Recent Developments in Japanese Oyster Culture Industry

This report describes recent developments and changes in the Japanese oyster industry which have occurred over the last decade. The last full review of the Japanese oyster industry was published in 1950 (Cahn 1950). A description of the Hiroshima oyster culture system was published by Korringa (1976) from observations he made during 1971 to 1973. This report attempts to describe the more recent and future trends of the industry. This report has been produced from a scanned original and may therefore contain some formatting and other inaccuracies.
