Findings of a Brief Water and Effluent Survey carried out at A. Christies Ltd

As part of the North East Scotland Strategic Study, Seafish has been involved in briefly visiting representative companies in the region to survey water use and effluent production. The purose of these visits is to estimate the general reductions in both water use and effluent strength which could be made by introducing waste minimisation. This report summarises the findings of the rief visit to A. Christies Limited, carried out on 28 April 1999.

The Effect of Soak Time on the Quality of Cod in Set Nets

The quality of cod resulting from net immersion periods (soak times) of between 3 and 48 hours was investigated. The trials were carried out on a 9 m boat along the Yorkshire coast during July and September 1991. The fish which were alive when brought on board were in excellent condition. After 9 hours soak the freshness of the cod progressively reduced as the physical damage increased. Over half the cod from the 48 hour soak time were spoiled beyond marketability. Recommendations to help assure quality are made.

Raising Standards in the Port Sector Quality/Standards Audit - Newlyn

As part of Seafish’s policy of encouraging higher standards of quality and hygiene in the ports sector, a survey of landing and sale operations was undertaken at Newlyn on the 9th and 10th August at the invitation of local interests. The following notes provide a brief record of observations with regard to the standard of existing facilities, equipment and operating practices for landing and sale. The investigation extended from the fish quays, market and dock estate but excluded merchants premises and vessels. The notes are intended to highlight any problem areas and form the basis for discussion between interested parties to raise standards where required, and to promote the Port of Newlyn.

Scallop Predation by Crabs, in Relation to the Development of On-Bottom Cultivation

The feeding success of four species of crabs (Crustacea : Brachyura) which are potential predators of the scallop Pecten maximum (L) was studied under laboratory conditions. Liocarcinus depurator was the only species not to prey on scallops of 4 and 5 cm shell height, whereas Liocarcinus puber. Carcinus maenas and Cancer pagurus showed the greatest potential to prey on scallops and further experiments were carried out with this species using a wide size range of bivalve. Presented with scallops within the range 3-9 cm shell height resulted in the following trends : as prey size increased, the proportion of crabs feeding decreased, male and female crabs showed similar predatory behaviour, and marine fouling on scallop shells had no significant effect on crab feeding. These findings are discussed in relation to the potential for bottom culture of P. maximus.

The Performance of High Speed Fishing Vessels in Service

The report describes a series of speed/load/fuel consumption trials on a group of commercial fishing vessels, and from the results, comments on the need to identify the correct operating criteria when drawing up specifications for such vessels.

Gill Net and othr Set Net Fisheries in Cornwall

'Set Nets' constructed of various man-made materials offer a highly efficient means of catching fish. The majority of vessels under 10m in length around the Cornish peninsula are at some time of the year actively engaged in the use of set nets.

Trawl Door Development Project: Project C. Flume Tank Testing of Quarter Scale Doors

This project is the second by a summer vacational student on the subject of testing model trawl doors in the Seafish Flume Tank in Hull. Progress on equipmnt and instrumentation has been made and a standard procedure of testing various types of trawl doorshas been recommended.

A Review of the Second International Conference on Molluscan Shellfish Safety

The Second International Conference on Molluscan Shellfish Safety was held in Iioilo City, The Philippines on 17-21 November 1997. This was the fourth in a series of conferences relating to Molluscan Shellfish Safety, the others being The First International Conference on Molluscan Shellfish Safety in New South Wales, Australia in 1994 and prior conferences in 1998 and 1992 on Shellfish Depuration in the United States of America and France. The scope of the conference encouraged a range of food safety related issues to be raised and provided researchers and industry with a picture of the range of factors which can affect shellfish safety. This report contains the abstracts of the papers and in some cases a precis of the presentations. The conference recommendations are also reported. An appendix outlining some of the illness associated organisms detailed in the papers is also included.

The Impact of Whelk Handling/storage Methods on the Product Quality

Samples of whelks were held in ambient, chilled, iced and immersed conditions. Those held in ambient conditions resulted in a poor quality cooked product.
