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.

Assessment of Blue Whiting Acceptability in Institutions

These acceptability trials were commenced in September 1975 using blue whiting from the catch off the Artic Privateer which were processed into block fillets in Aberdeen (AIS Report 146). They were continued in 1976 using block fillets processed in Stornoway (AIS Report 171) and extended in 1977 to include single skin-on fillets processed in Stornoway. In each case the blue whiting block fillets were battered and deep fried – the normal method of preparing fish in the hospital or school concerned. Unless specific questions were asked neither the hospital staff nor the school children participating in the trials were informed that the fish species being served to them was blue whiting. The results obtained suggest that provided the fish are suitably size-graded, blue whiting prepared in this way represents an acceptable product to institutional diners who would normally choose fish.

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.

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.

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.
