    Degritting of King Scallops

    Dredged scallops are known to contain ‘grit’ in the form of sand, silt, mud or broken shell. Although washed out in processing, this contamination limits the marketability of these scallops as a ‘live’ product and detracts from their value in comparison with scallops landed by divers. The initial part of this work has confirmed the considerable extent of grit contamination of commercially harvested scallops and that it is effectively removed in the production of a processed product by shucking and washing the meat, but it has also shown that the eating quality of ‘gritty’ scallops deteriorates rapidly if held unprocessed in the shell.

    The Evaluation of Ghost Fishing Preventors for Shellfish Traps

    This report describes and investigation into the phenomenon of 'ghost fishing' by shellfish traps. Ghost fishing can occur when fishing gear is lost from the control of its owner and continues to produce fishing mortality.

    Selectivity Trials of Seine Net Codends - MFV 'KESTREL' (INS 253) - April 1990

    This report describes the comparison between three different mesh sizes of cod end in order to assess selectivity criteria. The cod ends were 90 mm x 120 meshes, 90 mm x 100 meshes, 110 mm x 100 meshes. All were diamond mesh configurations. The results showed small increases in the L.50 characteristics but overall the discard rates for each cod end were comparable. The trials were carried out with and without a small mesh cod end cover.

    A Pilot Pot Fishery for Nephrops Norvegicus off the Northern Ireland coast

    The study was managed by officials from DARD, ANIFPO including the owners of the vessels engaged in the study and AFBI who carried out scientific monitoring of the pilot fishery. With the introduction of the Irish Sea cod recovery programme and its associated temporary sea area closures, several Northern Irish fishing vessels were displaced. They were encouraged to find sustainable alternatives to complete their annual fishing plans. Amongst the fishing vessels affected were four small (under 12 metre) vessels, which had traditionally targeted cod using gill-nets. The closure effectively stopped this fishery. As a result the four vessels, like many of their larger colleagues diversified into the Nephrops fishery using trawls. However, with the increasing costs of fuel and other overheads, combined with reductions in the landed price for Nephrops, the owners of the four vessels, together with the ANIFPO, decided to investigate alternative fishing opportunities. Following internal discussion, and with DARD’s Sea Fisheries Division, an application for funding was submitted to allow sea trials in the “open Irish Sea”, to examine the practicalities of using pots/creels to catch Nephrops. While creels were used in Strangford Lough, and other similar Loughs around Scotland, the possibility of using creels in areas traditionally trawled had not been investigated.

    The Transport Chain of Velvet Crabs from Orkney, the Western Isles and Northumberland to Spain - A Preliminary Review

    This study aims to examine the transport chain between 2-3 main fishing areas in the UK (Orkney, the Western Isles and East Coast-Northumberland) and the main market for velvet crabs, which is in Spain.

    Separator trawls as a tool for improving selectivity for cod

    This paper describes the results of comparative fishing trials, under commercial conditions, using a standard trawl and a separator traw. The target species in the fishing area were cod, haddock, whiting, lemon sole and plaice. The separator trawl was fitted with a 120mm lower codend; the upper codend and that on this standard net were 100mm. The trials involved about 90 paired tows over a period of 10 weeks. 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.

    A demonstration of "Outrigger Trawling" in the SW of England on MFV Admiral Gordon

    The aim of the project was to demonstrate an alternative fishing method commonly known as Outrigger trawling. This involved replacing the heavy beam trawls which are normally towed by the vessel with two demersal trawls, each trawl spread with its own set of trawl doors and towed from the derricks. This change alone will have a significant impact on bottom and gear drag. The steady increase in fuel prices was another driver for the fleet to look at alternatives to beam trawling. By adopting the outrigger fishing method vessels can reduce their fuel consumption enabling increased profitability and a reduction in environmental impact.

    Economics of the UK Fishing Fleet 2019

    The report presents economic estimates at UK, home nation and fleet segment level for the UK fishing fleet. The estimates are calculated based on samples of fishing costs and earnings gathered by Seafish as part of the 2019 Annual Fleet Economic Survey
