An Assessment of D.A. Massonage and Mortality of the Brown Crab Vivier Transport

Examination made on two consignments of brown crab exported from the UK to Spain. The aim was to assess the loads for quality, marketability and mortality and to account for the differences observed. In particular the relationship between physical D.A. Massonage and mortality was investigated and the causes of D.A. Massonage were discussed at some length.

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.

Bulletin FT3_The use of artificial seawater in mollusc purification

Seafish trials with mollusc purification have made extensive use of Artificial Seawater (ASW) in both laboratory and commercial tanks. This bulletin is aimed specifically at the use of ASW for bivalve molluscs and combines technical data from MAFF Laboratory Leaflet No. 39, published in 1977 and entitled 'Artificial Seawater for Shellfish Tanks' and experience gained by Seafish. For more detailed information the MAFF Leaflet or Seafish should be consulted.

Biodiesel at Sea

This document provides a non-technical summary of sea trials in a ~10 m class potting vessel running comparative fuel consumption tests using red (fossil) diesel and biodiesel. The vessel, FV Ma Gandole, is powered by a 20 year old Volvo MD70B 6 cylinder, normally aspirated, 120 hp diesel engine coupled to a 3:1 reduction gearbox, assumed to be fairly typical of many power plant of the Newlyn ~10 m class fleet. The sea trials demonstrated that both fuels started the engine equally well, and the vessel was felt to handle and perform equally well with either fuel.

Seafish response to GLA Licensing Standards Consultation

This dealt mainly with the GLA's own licensing standards, which it issued in 2006. It contains a section that deals specifically with shellfish gathering in which th GLA's very broad interpretation of 'shellfish gathering' is under review.

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.
