Online Elementary Food Hygiene Segment Ten: Essential food hygiene for fish friers

This is the tenth segment of the written learning materials for the Elementary Food Hygiene (online) training programme.

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.

Operation of the Advisory Service & Analysis of Results April 82 to April 83

The Advisory/Inspection Service of the Sea Fish Industry Authority has now completed its fifth successive year of operation under contract to the Department of Health and Social Security (DHSS). Each of the 14 hospital regions in England was visited for a one week period. Additional one week visits were made to different districts in the two largest regions, ie West Midlands and Yorkshire, making a total of 16 visits. As a result of these visits 722 samples of fish were collected from a total of 371 hospitals and assessed according to the criteria outlined in the WFA/Torry Purchase Specifications.

Recipe Development of Six Cockle and Mussel dishes

As part of its overall programme for expanding the market for under-utilised shellfish species, the White Fish Authority contracted a well-known shellfish processing company to undertake development work on new products based on cockles and mussels. This report outlines initial work carried out on seven products that, because they did not fit into the company’s marketing plan, were not taken beyond the recipe development stage.

Scallop Spat Collection Trials 1981/1982.

The objectives of the 1981 and 1982 spat collection trials were to obtain further information on the type and deployment of collectors in order to maximise their efficiency. Peak settlement in 1981 occurred in early July for Pecten and Chlamys, with a maximum average yield of 605 and 649 spat per collector respectively. In 1982, the peak of settlement occurred in late June, possibly before the bulk of the collectors were placed in the sea and the maximum yield for Pecten and Chlamys per collector was 451 and 185 respectively. Initial trials using different collector materials were carried out to establish the most cost effective type of bag and filler. These trials will continue.

Investigation into Methods of Providing Accurate Box Weights when Boxing at Sea

As part of the 1982-83 MAFF commissioned research and development programme the SFIA is studying fish handling methods at sea and on shore. Boxing at sea has advantages of fish quality and yield, and efficient handling, but currently boxes are being detrimentally overfilled with varying weights of fish.

Over Wintering of Crassostrea gigas Seed at 8 Locations in the UK

Pacific oyster seed of three size ranges were held in the sea over the winter of 1973/74 at eight locations around the UK. Survival and growth rates at each site were monitored at near monthly intervals. Survival of the smallest size (1.5 to 2.5mm) exceeded 75% at only two locations, both warmer than the other six, and fell below 30% at three locations. Surprisingly the two warmer locations produced poorer results with the medium sized seed (5 to 6mm), with survivals of 25 and 45%, compared to 30 to 50% at the cooler sites. Survivals with the large seed (10 to 12mm) at one warm and one cooler site were 86 and 80% respectively. Significant growth was recorded at only the two warmer locations, being about a 50 fold increase in weight in the heated water at Hinkley Generating Station and 5 to 7 fold at Guernsey. At the other sites growth did not exceed 85% and was zero for several. Until the reasons for the variability in survival of the smaller sizes of seed have been determined, commercial growers are advised to exercise great care if they attempt to overwinter in the sea seed of less than 10mm in size.

A Study to Forecast the Commercial Costs of Farming Turbot and Dover Sole

The 1975 equivalent report (Technical Report 130) was based on research results obtained from the White Fish Authority’s (WFA) and the Ministry of Agriculture Fisheries and Food fish cultivation programmes. At that time, because, of course, industry’s involvement was not at the commercial stage, several of the important costing parameters had to be taken from fresh water trout farming. Predictions, however, were that such schemes were viable. Since 1975 the WFA’s Research and Development Programme has largely been directed to confirming the predictions and to establishing commercially appropriate costs. During the period, commercial participation has become more active, particularly with turbot.
