Noise Reduction Methods on European Fishing Vessels

Much work is being done in Europe to study the sound levels and exposure times of fishermen whilst at sea carrying out their duties and this is a means of assessing the risk of hearing damage. A way of reducing risk is to limit and reduce noise in the spaces of fishing vessels to a safe level. Since many vessels have dangerous levels, practical onboard research into cost-effective noise reduction methods is being carried out. The main object of this report is to describe some work being carried out to reduce one particular problem, that of hydraulic noise.

The integrated boxing of Nephrops - Comparative Trial

This trial arose due to concern about spoilage of typically handled Nephrops norvegicus (nephrops) catches. For the most common 1 day trip the practice is not to use ice and generally, at best, 2 day trip vessels top ice only to boxes in the hold. There has been a trend toward landing whole nephrops rather than tails an there is widespread belief that direct icing is harmful to whole nephrops. This comparative trial applied proper boxing principles, ie, weighing and correct icing, alongside usual stowage practice. Two successive trips were made on a representative vessel of each type ie, 1 day and 2 day trips from Mallaig. The fish quality results were obtained by following the trial catches through processing at D A Macrae Ltd., Sunderland. Apart from weighing and icing at sea the trial included observations of practice and temperature. The result indicate that for whole nephrops proper boxing and icing can reduce temperatures of the product to less than 2°C which gives considerable value advantage to 2 day trip catches on processing, and a discernible freshness improvement to 1 day trip catches. Icing did not have any apparent adverse effects. Weighing at sea was found to be operationally feasible with potentially suitable accuracy for commercial application.

Trials to Determine DAF Fish Effluent Treatment

As the Urban Waste Water Treatment Directive (91/271/EEC) demands tighter control of the quality of effluent discharged into ~EU controlled waters, many coastal processors face dramatically increased effluent disposal charges. It is likely that most companies will use basic solids separation equipment to minimise effluent disposal costs, whilst larger companies may opt to use more sophisticated equipment to further treat the effluent themselves. Trials were carried out at three factories to determine the effectiveness of rotary wedge wire screening following by dissolved air flotation (DAF) for treating herring and white fish processing effluent. A range of chemical flocculants were tested to optimise DAF treatment. This report has been produced from a scanned original and may therefore contain some formatting and other inaccuracies.

Quality Audit of the Port of Ardglass

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

Highland Regional Council Fisheries Plan 1991-98

This report is a summary of the work carried out by the Seafish field team during April and May 1991. The subjects covered include a review of the international trade in fish and shellfish and the local issues relating to the fisheries and fishing harbours of the Highland Region.

Quality Audit of the Port of Eyemouth

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

Satellite Based Monitoring System for EEC Fisheries

This report has been prepared by Seafish as a contribution towards a study in which the merits of a satellite based montiroing system are to be reviewed against a number of fisheries management options and for which the basic parameters of a proposed system would be defined. The remit of Seafish is to provide necessary information regarding the range of nations' fleets which are based in the northern waters of the EEZ of the Community (basically the areas of the Baltic, Irish and North Seas and of the Atlantic Ocean north of Finistere). At present the waters are fished by Member Nation vessels from Belgium, Denmark, Eire, France, Geermany, Holland, Spain and the UK and much of the commentary is made in respect of the efforts of these fleets.

Site Visit Report for F. Smales & Son (Fish Merchants)

This report summarises the findings of a three day audit of F. Smales and Son Ltd. from 27 to 29 May 1998. The purpose of the visit was to determine water usage and effluent production in filleting (including washing) and defrosting. However, some general observations and problems identified with water use and effluent production in other processes are included.
