Further Evaluation of Square Mesh Panels to Improve Selectivity for Cod in Demersal Trawls

The report describes the most recent in a series of attempts to improve the release rates of sub legal cod from trawls. The work was carried out under MAFF Commission MF0612. In the main part of the trials square mesh side panels were used but they seemed to offer little, if any benefit.

Design and Commission of a Mussel Purification Plant at Kings Lynn

This report describes the design and installation of an eight tank mussel purification plant at Kings Lynn. This followed successful trials of a prototype tank incorporating multi-layer stacking and partial reuse of artificial seawater. The operation of the plant is described together with the results of monitoring at higher water temperatures than those previously used.

Observations and Trials of Fish Handling on Small Vessels - Stage 2 (incomplete)

This project acknowledges the need for improvement in the quality of fish from inshore vessels, the majority of which are small and operate as day trip boats. The large fleet of inshore vessels under 16.5m lands an estimated value of fish of at least £100 million per annum. However, the quality of a proportion of this catch is often far from what it could be due to lack of facilities and temperature control.

Weighing/Grading at Sea Trials aboard MFV Craigmillar

This report summarises the results of the weighing/grading at sea trials carried out aboard the CRAIGMILLAR (MFV) during week ended 10 March 1987. The principal objective of the exercise was to introduce iced, weighed and graded at sea fish in plastic boxes into the auction sale system at Fleetwood with a view to improving home landings in terms of quality and presentation and thus raising the average market value of sales.

Instrumented Trials on 'Sharona II'

The vessel is a 22.62 metre (74 feet) wooden trawler from the yard of J & G Forbes at Sandhaven. The vessel has a propulsion engine which drives a five bladed fixed pitch propeller through a reverse reduction gearbox.

Artificial Lobster Habitats - A review

This paper reviews current knowledge on lobster (Honarus sp) life cycle and habitats. The information is intended to assist in the planning of an artificial island in Poole Bay with a view to ensuring that the habitat would be suitable for lobster habitation.

Estuary Profile Conwy N. Wales

The Conwy is the most westerly of the major estuaries in North Wales. The main shell fishery is for mussels valued at £34,000 in 1986. The fishery is under threat from a massive road tunnel scheme to be dug under the estuary in 1987.

Cuttlefish Quality and Handling Trials

In conjunction with the Marine Technology department's cuttlefish capture trials, the Fish Technology department conducted trials to investigate factors affecting cuttlefish quality. The trials studied the effects of both icing delay and gutting delay upon cuttlefish quality. Although the extent of the trials was limited they showed that cuttlefish spoil rapidly if not chilled and that even a short delay of 6 hours between bringing them aboard and icing has a significant effect on quality. The gutting delay trials have shown that the gut membrane of the cuttlefish is very strong, and for cuttlefish stored from capture at chill temperatures, it takes approximately 9-10 days before this membrane weakens, ruptures and effects the cuttlefish's quality. Some D.A. Massonage to cuttlefish was noted, caused by certain capture methods used, especially pots. See also Seafish Report SR467.
