Initial Trials to Extend the Storage life of Cod and mackerel using Sodium Hypochlorite or Ozone to Treat Ice and Refrigerated Seawater

Despite diminishing fish stocks and the higher prices which can be attained for top quality fish, poor quality fish is still being landed into UK ports. As well as addressing the more traditional handling problems Seafish has identified the use of techniques such as ozonation and chlorination which may enable the improvement of fish quality by reducing the rate of bacterial spoilage. Trials were carried out to determine the effect of sodium hypochlorite and ozone on the quality of cod and mackerel in treated ice or RSW. Holding mackerel in RSW treated with sodium hypochlorite reduced the rate of bacterial spoilage by over 50%; little improvement was seen in the quality of cod.

The Results of a Water and Effluent Study carried out at A. Darnell Limited in November 1997

In the near future new environmental legislation will add greatly to the cost and difficulty of disposing of waste water. This will present a significant problem to the fish industry. Seafish has commissioned a number of water audits in fish processing companies, looking at water usage and effluent production, with a view to minimising both.

Mollusc Purification Plant Fastnet Mussels

A new mussel purification plant has been constructed by Fastnet Mussels, at Bantry Bay in Southern Ireland. Under contract to BIM (The Irish Sea Fisheries Board) Seafish visited the plant to comment on its design and operation on the basis of their experience and current UK design criteria. This report describes the plant, which is not yet complete, and comments on its intended design and operation. Seafish Criticise the use of long, shallow, outdoor tanks on the basis of no water temperature control and potentially inadequate dissolved oxygen levels. Recommendations are made on the loading and operation of the plant on the basis of montiroing of dissolved oxygen levels.

Multi-Layer Mussel Purification Tank

This report describes the trials which subsequently took place following the design of the stainless steel multi-layer tank by Bead Engineering, to Seafish specification, and its installation at the premises of Heiploeg Lynn. The trials were conducted by Seafish as part of its 1988/89 MAFF Research Commission, Project NBA 16. A total of eighteen purifications were made with the tank using a single initial mix of artificial seawater to which ten percent make-up was added at each use. Bacteriological analysis showed that mussels purified satisfactorily throughout the trials and there was no detrimental effect on mussel storage life. It became clear during the trials that water temperature needed to be kept between 5° and 10°C to ensure satisfactory purification. This makes it essential to house the tank in a building in order to maintain temperature control. Following the first twelve trials the effect of overloading trays/boxes with mussels was investigated and it was possible to establish a safety margin on the nominal load of 15kg per box.

Shellfish Licensing - The French Experience

This is one of a series of reports Seafish are initiating to assess the possibilities of a shellfish licensing scheme for the UK. It looks at schemes in France, notably those for scallops for which there is experience going back to the early 1970s. These schemes are restricted to the territorial limits of up to 12 miles and are administered by the local Comite Interprofessionel des Peches Maritimes.

Survey of Clyde Fishing Ports

The survey details, the facilities and practices in the major and minor ports along the Ayrshire Coast and the Mull of Kintyre. The landings for the main species over the few years are also given.

Noise Level Reductions on M.F.V.

Following reports of excessive noise in the cabin of M.F.V. "Ocean Challenge" the propeller was changed to one of a highly skewed design. The S.F.I.A. monitored the change in noise and performance levels and found a reduction in noise of up to 25% with no significant reduction in performance.

Fresh Fish Supplies from Iceland

Following concerns expressed on Humberside about the future trade with Iceland and the loss of quality experienced with container fish, a mission was made to Iceland on October 1991. This report examines future trading patterns and identifies several reasons for the quality loss.
