Towing Requirements for a Pair Trawl (2 x 340hp Vessels)

This report contains the performance data of a FMA Buckie Pair Trawl - BT 154, rigged with 2 bridles and rockhopper gear. It expresses the power requirements in terms of warp tensions and settings of net speed, warp length and vessel distance and defines the best settings for fuel consumption.

ICES Area VIIf selectivity Trials. Single Boat Demersal Trawl MFV 'OUR OCEAN HARVESTER' (PZ403)

These trials to measure the selectivity of a trawl in a multi species fishery when fitted with a square mesh panel were carried out on the trawl fishing grounds off North Devon and North Cornwall. The results show an indicative benefit in the use of the panel for round fish but it has been extremely difficult to achieve satisfactory statistical data due to the large number of variables.

Deepwater Fishing along the Continental Shelf - Seafish Seminar held at Banff - 15 November 1991

Deep water species found along the Eastern Atlantic Continental Slope are now being marketed in France, the USA and Japan. They are known to British fishermen but there is as yet no commercial British fishery. This report reviews the current state of knowledge based on a seminar held at Banff in November 1991.

An Investigation into the Conditions Required for the successful Shucking of Wash Mussels

Wash mussels taken from intertidal beds have exhibited problems during the shucking process to obtain good quality meats. The problem is identified as relting to rapid heat transfer to loosen the meats and the thinner shelled mussels from sub-littoral zones are likely to be more suitable for processing.

A Study of Squid and Its Potential in UK Water

This report is aimed to collate the current information available on squid so as to review the basic knowledge of squid and to clarify this fishery and its potential. Included in this report is a review of the animal's biology and fishery, that is to say, the scale of this fishery in the UK, the fishing methods, methods of preservation etc.

A Profile of the South Coast Fisheries - Lyme Regis to Selsey Bill

The fishing sector of the Southern Sea Fisheries District, of Lyme Regis to Selsey BIll, is typified by small-boat (below 12m) operators who collectively lack organisation and representation. It is estimated from anecdotal evidence (see p.2) that in the order of 350 fishing boats operate full time from numerous bases seriously lacking in infrastructure support. Most boats are owner operated, with the only fleet operation being that of Johnson’s Sea Enterprises of Portsmouth who operate four large beam trawlers. In excess of 300 other craft, all less than 12m operate on a part time or casual basis.

Comparative Sea Trials of plastic stack-next and stack only fish boxes

Although the wooden fish box is still commonly used in Scotland for handling fish both at sea and ashore there is a growing acceptance of an eventual change from wood to plastic boxes. Of the two types of plastic box available (stack-only and stick-nest) the stack-nest is considered a most suitable replacement and is already in use ashore but there have been reservations concerning it use at sea. From June to December of 1986, Seafish carried out a series of comparative trials on Scottish vessels to assess plastic boxes when used at sea. The boxes used were a new stack-nest design, produced to a Seafish specification as a replacement for the wooden box, and an existing plastic stack-only box of the same nominal capacity of 70 litres. The trials are described and discussed in this report This report has been produced from a scanned original and may therefore contain some formatting and other inaccuracies.

Mussel Spat Collection and Cultivation Trials in Wales using Bouchots 1987-89

This report describes an investigation into the viability of using the French bouchot pole and Italian pergolai net stocking method for cultivating mussels in South Wales. A modified trial was established in North Wales to accommodate reduced tidal ?. Seed was collected from Morecambe Bay and Caemarfon and monitored over a two year growing period. A computer program was developed to compare growth performance at each site. After a T. Wrayo year growing cycle the mussels averaged 47 mm; 38% meat yield and trade opinion indicated a minimum price of 450/tonne. Costings suggest that for an investment of 20,000 a return of 45,000 per annum is projected.
