Report on Pulsed Light Processing of Seafood

The aim of this project was to assess the potential for the use of pulsed light to extend the shelf-life of seafood by reducing the microbial loading on the product surface. Trials were undertaken to establish if pulsed light could reduce the level of naturally present organisms including Pseudomonas on raw cod, smoked salmon slices and cooked whelks. Further trials explored the inactivation of Listeria innocua inoculated onto the surface of cooked cockles, cooked and picked crab meat, smoked salmon slices and cooked whelks.

CONTROL OF SUPERSATURATION IN THE HATCHERY

Supersaturation can occur naturally in high-energy environments e.g. from wave action or dam spillways; or as a result of excess photosynthetic activity. In the aquaculture hatchery, supersaturation can be caused by a sudden increase in temperature e.g. in long pipe runs exposed to the sun, by entrainment of air through leaking joints or pump seals, or by injection of pressurised air at depth.

Good Manufacturing Practice: Guidelines for Nephrops Fishermen

These guidelines provide advice to Nephrop fishermen on good manufacturing practice (G.M.P.). Their purpose is to help fishermen to comply with food law and to secure a better return for their products. This includes ensuring food safety, maximizing product quality and meeting the needs of the market. Whilst these guidelines contain helpful technical information some of the legislative content may now be out of date.

This report describes the UK results of that survey.

Reducing Drag in Towed fishing Gears - Fishing Trials to Evaluate the Performance of a trawl Constructed from T90 ('turned mesh') Netting

This report describes a demonstration trial of a single-rig, demersal whitefish ‘Rockhopper’ trawl constructed entirely of T90 or ‘turned mesh’ netting. This is the first time that T90 technology has been used in this way in the UK. The trawl used for this trial was designed and constructed by Icelandic trawl manufacturer, Fjardanet which has been pioneering this technology for a number of years. Descriptions of the fishing gear used are included. The report describes some background to the development work and the concept of T90 technology. Eight days of commercial fishing trials were carried out in January 2008 using the Shetland based vessel Mizpah operating on local fishing grounds about 50 miles NE of Lerwick. Despite being hampered by poor weather a total of 21 hauls were completed. The aim of the trials was to evaluate the performance of the T90 trawl with reference to fuel savings as a result of the reduced netting drag associated with this technology. This was done by measuring the main gear performance parameters and comparing them with those of the vessel’s existing gear of the same general dimensions. Some catch sampling was undertaken to examine other reported attributes of T90 trawls such improved catch rates, size selection and catch quality. From a gear performance perspective the T90 trawl compared well with the vessel’s own trawl. The information gathered on the fuel efficiency aspects of the gear however did not show any significant benefits from the T90 trawl despite indications that the netting drag had been considerably reduced, (~20%). The findings from the catch data were inconclusive. There were some indications of larger size ranges of some species being caught and retained by the T90 trawl but the findings did not appear to bear out the findings and experiences of the Icelandic fishermen to the same extent. There was more loss of marketable size grades of some species, particularly whiting associated with the T90 trawl. This was thought to be as a result of the more consistent mesh opening noted throughout the T90 trawl. The positive side of this was that there were no discards recorded. There was no noticeable difference in catch quality detected. The results showed that the combination of the T90 trawl fitted with a conventional diamond mesh codend of the same mesh size produced the best commercial results. The results were insufficient to draw any firm conclusions on the overall effectiveness of the T90 trawl and a number of proposals for further work have been highlighted.

Recent advances in the use of DNA and other techniques in the seafood supply chain

There have been several recent reports in the media concerning mislabelled fish, both in the national and international press. Some reports reveal obvious fraud where an expensive species is substituted with a cheaper one such as pangasius being sold as cod, or inadvertent substitution of species, where it is equally possible that the expensive species is sold as the cheap species, and vice versa. This fact sheet outlines some of the techniques currently used to accurately identify seafood and seafood products, and reviews some of the benefits and limitations of the latest DNA and other techniques used for identification purposes within commercial, enforcement and fisheries science.

Loading capacities and criteria for the successful depuration of cockles (Cardium edule) in small scale standard design depuration systems

These trials set out to investigate whether increased loadings oc cockles could be successfully depurated using the current standard of 30kg for comparison. Initial trials also involved a comparison between hand-raked cockles and cockles harvested by a towed-cage fluidized-bed dredge and concluded that this form of mechanised harvesting yielded cockles that were suitable for depuration. Results indicated that successful depuration could indeed by achieved with 90kg loading at the current minimum depuration temperature of 7°C. The results at 16°C for both 30kg and 90kg were inconclusive but suggest that depuration of cockles in general at this temperature warrants further study.
