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.

Good manufacturing practice guidelines - Live bivalves workbook

Seafish have produced this workbook to assist live bivalve shellfish operators in producing a high quality, safer live bivalve in compliance with legal obligations. It is designed to be used in the production environment, onboard the harvesting vessel or foreshore. Whilst these guidelines contain helpful technical information some of the legislative content may now be out of date.

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.

Investigation into Potential Fuel Saving using Auxiliary Sail MFV ''Danbrit''

This report covers the analysis of the technical requirements of auxiliary sail in terms of the main parameters: wind climate experienced by the vessel, ability of the vessel to carry sail as limited by her stability characteristics, and the derivation of overall fuel savings under these conditions. Also included is a comparison of the fuel which could be saved with the present annual fuel consumption in monetary terms to assist investment appraisal.

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.

Specification for Freezing and Packaging of Oyster Meat

This report is a collection of six specifications developed by the Authority to assist oyster processors and product manufacturers. The recipes and procedures are based on work conducted by the Authority’s Market Development Unit to a point at which interested firms can sophisticate the products to suit their won systems and requirements.

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.

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.
