FS3-02.08-Fillet discolouration

Whitefish flesh naturally changes colour with age and depending on how it has been handled after capture. Initially, whitefish species such as cod and haddock have a blue, translucent colouration, which changes to white after a couple of days. After this the flesh can become yellow and then brown but it is generally considered inedible before it changes into these colours. However there are also other reasons as to why fish flesh can be classed as discoloured. This factsheet provides a very basic summary about the reasons for colour changes in whitefish.

Lobster Stock Enhancement Trials

This report describes the progress with the lobster stock enhancement trial since May 1985, proof now exists in the wild for subsequent recapture.

Aggregate Dredging Fishery Perspectives

The extraction of marine aggregates for civil construction use has increased dramatically in the last five years. There are strict procedures governing the issue of prospecting and extraction licences to dredging companies. Crown Estates Commissioners are the responsible Authority. This report highlights procedures but also draws attention to the risks posed by these activities to fishing interests. This report has been produced from a scanned original and may therefore contain some formatting and other inaccuracies. In cases where this affects the technical content, a paper copy of the original report can still be obtained from Seafish.

Turbot Hatchery Production 1981

During 1981 a total of 988,900 day one (dl) turbot larvae commenced rearing at the Hatchery at the Marine Farming Unit, Ardtoe. These comprised of 544,600 larvae from WFA spawning stocks at Ardtoe and Hunterston and 434,400 larvae originating at Scottish Sea Farms Hatchery at South Shian. In addition, a batch of 19,000 turbot/brill hybrid larvae was received from MAFF Lowestoft. Larval rearing methods closely followed those of 1980. The eggs produced at Ardtoe in 1981 (6.5% hatching rate) were of poorer quality than those of 1980 (16% hatching rate). This almost certainly reflected mortalities among proven female spawners between the two seasons.

Alternative Stimulation in Fisheries

The objective of this concerted action is to review current knowledge of fish behaviour and the stimuli to which they react. One aim of the review is to reveal where improvements might be made to current practice in fisheries. Question might be: is there an alternative to heavy ground gears that are thought to damage the sea bed perhaps using sound pulses, electric fields, laser beams or water jets? Why do not all fish small enough pass out through grids and square mesh windows built into codend extensions? It is widely recognized that there is a fund of knowledge about fish behaviour as well as the properties of physical and natural stimuli that is not made use of in applied fishing gear technology.

Lochinver Port Quality Audit

This report presents the findings of a Quality Audit of the fishing port of Lochinver that examined the quality of raw material supplies to the port, standards of physical infrastructure, operating practices and management controls.

Brixham Fish Market Study

For a number of years Torbay Council and its partners have been working to put in place an effective plan for the regeneration of the town of Brixham, including the provision of fisheries infrastructures that would ensure the long-term viability of the local fleet and fish-related businesses. Previous studies identified major problems in the port relating to lack of space, poor road access, insufficient parking and inadequate and unhygienic facilities for the landing and sale of fish, its processing and onward distribution. As a first stop to the regeneration of the town, Torbay Development Agency (TDA) is planning a new fish market and landing quay to be built on reclaimed land and for the existing fish market to be upgraded to provide modern hygienic facilities that will accommodate fish processing and storage.

Instrumented Trials on 'Destiny'

A Seafish trials team carried out an instrumented sea trial in December 1989 to investigate the causes of excessive exhaust temperature on the main propulsion engine. A report on these trials was produced as CR7. It was confirmed that the engine was not subject to overload in any of its fishing or steaming modes. The worst situations involved seining activitiers in which the engine was required to provide power to the jhydraulic seine winch and rope reels while running at low speeds (500 to 700 engine revs/min) in order to limit forward thrust from the propeller.
