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.

Blue Whiting Processing Trials Stornaway 1977

The almost universal adoption of 200 mile fishing limits has resulted, to a large extent, in the exclusion of our distant water fishing fleet from their usual fishing grounds, and consequently in a shortage of traditionally acceptable fish such as cod and haddock. This shortage has caused a predictable series of price increases, and shown a need to exploit non-traditional species such as blue whiting, which can be caught in large quantities around our own coast and within the EEC controlled fishing areas. Blue Whiting (Micromesistius poutassau) is a small white fish, a member of the cod family, which congregates in large quantities to the north west of the UK during its springtime spawning season. Throughout the remainder of the year the blue whiting stock disperses throughout the north Atlantic. Estimates of the stock vary between 8 and 12 million tonnes, of which 2 million tonnes could be harvested annually without damaging the stock. Despite increasing fishing activity by foreign vessels, fishing mainly for fishmeal, the stock still remains virtually unexploited.

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.

A Survey of Current Research on the Selectivity of Fishing Gear

The selectivity of fishing gears has become an important issue in recent years as a consequence of greater awareness of the necessity to conserve fish stocks, and to take only those species and sizes of commercial value. This report summarises current research work in this field and the ‘state of the art’ of different selectivity investigations. Research is being carried out by several international research organisations and among the leading authorities are the DAFS Aberdeen Laboratory and MAFF’s Lowestoft Laboratory. This report has been produced from a scanned original and may therefore contain some formatting and other inaccuracies.

Exploratory Voyage by DET 'Swanella'

In the Autumn of 1973 the diesel electric stern trawler SWANELLA was chartered on behalf of the Ministry of Agriculture, Fisheries and Food for an exploratory fishing voyage in deep water to the West and North West of the British Isles. The areas in question have not hitherto been exploited by commercial fishing vessels but in the twelve months prior to SWANELLA’s voyage they had been surveyed in part by fishery Research Vessel CIROLANA.

Operation of Blue Whiting Surimi Plant - Stornoway April/May

Industrial Development Unit staff working in conjunction with technologists for the Japanese company, Nippon Suisan Kaisha Limited (NSK), have recently completed a trials programme in which Blue Whiting (Micromesistius Poutassau) was processed into Surimi, using specialised equipment installed in the Rolf Olsen fish processing plant at Stornoway. The product has since been sent to Japan for marketing trials (which will be attended by IDU staff) during 1978.

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. This report has been produced from a scanned original and may therefore contain some formatting and other inaccuracies.

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.

Summary, Findings and Conclusions of Mackerel Research

Mackerel is a well-known but not often used fish. Although it is available fresh, smoked and canned, it is under-utilized. The White Fish Authority has undertaken to determine why mackerel is not universally popular, and to discover future market potential and market opportunities. During Stage I, in July 1976, nearly 2,000 housewives were interviewed at random, representing an estimated 18,500,000 housewives in the country. For Stage II, group discussions were conducted in August 1976 with six groups of housewives in the North and South, recruited on the basis of their mackerel usage. 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.

Over Winter Growth Pecten maximus in a Nursery Scallop

The concept of an overwinter nursery process for Pecten Maximus spat arose on sampling spat settlement in artificial collectors in 1975 (Ref 1). It was noticed that the major proportion of the collected stock was still small and fragile (mean size 8 – 9mm) about four months after the peak settlement in July. By this time (November/ December) the sea temperature had fallen from 12/13ºC at the end of October to 8/9ºC at the end of December, and eventually the temperature fell to 6ºC by the end of January. There was some evidence of cessation of growth and significant mortalities of the smaller scallop spat over this winter (see Ref 2). There was, therefore, the possibility of promoting growth and survival of these small spat, indoors, over the winter and perhaps thereby shortening the overall culture period for Pecten maximus.

Results and Summary of Conclusions of Interviews Amongst Fish Friers Selling Blue Whiting and their Customers

Following the experiment amongst 7 volunteer fish friers selling complimentary quantities of frozen, skin-on, blue whiting block or butterfly fillets in their retail fish and chip shops (see report of June 1976), 4 of the nominated friers opted to continue selling blue whiting on a trial commercial basis. Pre-arranged quantities of frozen, graded, skin-on block fillets in 4 kg shatter packs were made available to these friers beginning the week of 16 August, 1976, at a price of £3.50 per stone. To date, the quantities delivered by the White Fish Authority (WFA) average 1 stone per outlet per week for 3 of the fish and chip shops, and 2 stone per week for the remaining 1. After allowing a reasonable amount of time for the novelty aspect to wear off and blue whiting to become an accepted item for sale in the 4 shops, in late October the WFA commissioned interviews to be conducted during normal trading hours in each of the 4 shops. The interviews were conducted by professional interviewers, one of whom spent a day in each location interviewing first the frier and then customers at random who ordered blue whiting.

WFA Fisheries Training Centre and Flume Tank Description and Account of its First Period of Operation

The White Fish Authority’s fisheries training centre was officially opened on the 27 February, 1976 by the, then, fisheries Minister Mr Fred Peart. It introduced a powerful new tool, in the form of a flume tank, in which large scale models of trawls and other types of fishing gear can be demonstrated and tested. Up to the 31st October, 1976, when it was drained for three weeks for its warranty survey, the flume tank had been run for 541 hours on 153 days, with virtually no defects in eight months effective operation. In other words the tank was utilised on all but 22 working days in its first period of operation. This report describes the new training centre, explains how the flume tank works and outlines the type of work done during this first period.

Box Washing and Handling system

The Aberdeen Fishing Vessel Owners’ Association have, for a number of years, operated a Box Pool within the Port of Aberdeen. The boxes, owned by the Box Pool, were until recently, wooden market trunks, capable of containing 8 stones of fish. They were delivered to the Fish market during the night to meet the estimated demand of the subsequent landing. After the sale, the boxes were taken to the Merchants’ fish-houses from whence they were uplifted by the Box Pool’s own collection service during the afternoon and taken to their premises on Albert quay. Recognising the longer term need to restructure their Box Pool, the A.F.V.O.A. had engaged MAS on several occasions over the past five years to undertake studies concerning the operation of the Pool under different sets of circumstances. A comparative costing exercise covering a number of different washing systems, operated on the continent as well as the UK, resulted in the drawing up of a general specification for a washing machine, which would enable the Box Pool to offer an economical services at their existing site, while producing a thoroughly clean box.

Mackerel Promotion Exercises Conducted in 6 Supermarkets - London Area

At the time of writing, mackerel is probably the only very large resource, apart from blue whiting, now available to the UK fishing fleet and consequently catch rates have risen dramatically during the past 3-4 years to a point approaching 10% of the total UK catch, and mackerel has now overtaken cod as the main species landed by UK vessels. However, the increased landings of mackerel have not been matched by a corresponding growth in the home market with considerable quantities in the past to or three years being either reduced to fish meal or transhipped for export to Russia and other Iron Curtain countries – with the result that this highly nutritious species is seriously under-utilised in terms of human consumption in the UK.

A Study to Forecast Costs of Farming Scallops and Queens

Biological data, from controlled culture trials with scallops (Pecten maximus) and Queen scallops Chlamys opercularis) on the Scottish west coast, have been applied to Japanese long line methods. Costs have been established and commercial viability is discussed for farming on a crofter basis, that is with a vessel, a vehicle and family labour provided free of charge. Although the early growth rate of Queen scallops is superior to that of scallops, the formers lower sales value cannot yet make its cultivation viable, even on the most favourable basis of allowing all market costs of a combined scallop and Queen operation to be charged against scallop production. However, if the significantly higher inert yield in cultivated Queen Scallops, compared to wild stock, were reflected in the sales value by only 25%, combined culture of the two scallop species would warrant further evaluation.

Progress Report on the Work of the Advisory Inspection Service from its Inception in January 1972 to July 1974

In its attempts to upgrade the quality and to increase the sales of fish to the institutional catering field, the Authority recognised the difficulties experienced by many organisations in purchasing fish. These difficulties stemmed more from inability to state the purchasing requirements correctly and from administrative procedures within the organisation, than from problems of supply. Standard purchasing specifications were therefore compiled and the Advisory/Inspection Service instituted, with the brief of implementing the usage of the specification and of monitoring the quality of the fish supplied against them.

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. 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
