Investigation on 'Maranatha II' (UL33)

The vessel was delivered in 1989 and, since that time, has suffered a number of partial failures of the propulsion engine, a Caterpillar 3508, rated at 765hp at 1440 revs/min. The failures have taken the form of premature failure of inlet and exhaust valves. At or about the time of failure, excessive lub oil consumption has been noted.

Fleet Structures Model - Biological Feedback

The Fleet Structures Model* (FSM) is a predictive model under development by the Sea Fish Industry Authority. Its purpose is to simulate aspects of the structure and performance of the United Kingdom sea fishing fleet in order to make comparative assessments of fleet management policy scenarios. Because of the inherent complexity of the model it has been developed in separate sections. The first of these to reach completion as a stand-alone computer model is the Biological Feedback phase. This predicts the effects of catch levels on fish stocks, and the consequent effect on catch rates as stocks rise and fall.

Survey of Clyde Fishing Ports

The survey details, the facilities and practices in the major and minor ports along the Ayrshire Coast and the Mull of Kintyre. The landings for the main species over the few years are also given.

Mussel Purification Commercial Scale Trials

This report describes a series of trials conducted at Monteum Ltd., Shoreham using a modified crustacean holding tank, Mussels were obtained from the Wash and purified using the existing criteria advised by MAFF with the exception that as the trials progressed the number of mussel layers was increased to the maximum of six that the depth of tank allowed. In addition further trials were conducted with increased mussel density in the tank, the use of interleaf boards between layers and purifying mussels in bags. Water temperature, pH and dissolved oxygen were monitored and samples of tank water and mussels, both pre and post purification, were analysed for the bacterium E.coli and Faecal Streptococci. The trial ran from February to April 1987, when trials were curtailed due to the onset of the mussel spawning season, and were concluded during October to November 1987.

Norfish: Iceland - A Special Case

Both Iceland and Humberside have a mutual dependence on each other for a buoyant trade in fish and fish products. The report is based on an extensive study of the trade in recent years between the two fishing centres and a visit in October 1991 to SW Iceland to discuss future trading trends, especially in view of reduced trading barriers as a consequence of the Iceland joining the new EEZ.

Fleet Structures Model - Program Documentation

The Fleet Structures Model is a series of mathematical models developed by IDU which simulated the development of a national fleet in response to chosen policy scenarios. This report, which is one of a series, provides flow charts and program listings for the policy input programs together with the main model.

Regional Study - South West Scotland

The fisheries of South West Scotland are encompassed by the Ayr and Campbeltown statistical districts. Geographically they cover the Scottish Solway coast, the Firth of Clyde and Kintyre and the Inner Hebrides as far North as Colonsay. The Solway is dominated by the Queen scallop fishery centred on Kirkcudbright. The Clyde’s centres are Ayr, Campbeltown and Tarbert with a mix of white fish, shellfish and herring. The white fish include valuable hake but the herring fishery is tiny compared with a few years ago mainly due to a scarcity of the typical large fish much sought after by kipperers. Nephrops dominate the shellfish trade contributing some 30% of the Ayr district total value landed. Campbeltown district including the Inner Hebrides is dominated by shellfish landings in terms of total value. These contribute about 90% of the total of which 50% is from Nephrops. Though much of the shellfish is trucked out of the region, there are Nephrop processors in Campbeltown, Ayr and Scotland’s central belt. White fish is processed in Campbeltown and Ayr and Queen scallops at Campbeltown, Kirkcudbright and Newton Stewart. There are major concerns at the time of writing over disappointing levels of Queen scallop landings. The conflicting interests of trawlers and exercising submarines were highlighted by the tragic incident involving the Carradale vessel ‘ANTARES’. This issue is still of major concern in the area despite much effort towards a resolution.

Wash Development Group Progress Report

The Wash Development Group completed its first year of activity in December 1986. Much progress has been made with demonstrations of the continuous hydraulic suction dredge, but there is now a shortage of mature cockles and this position will not improve before 1988. Purifiction of mussels is now progressing and a limited amount of relaying has been attempted. The report outlines the next stage which is to develop a business plan for the Wash as a whole.
