These pages contain technical advice on the cultivation of halibut. They are complimented by economic modelling tools that enable you to explore how a potential halibut cultivation business might work. There are models for the hatchery, nursery, onshore and cage-based on-growing aspects of farming.

The potential impact of wild Pacific oysters on local biodiversity is being raised as an issue that has to be considered in environmental assessments of both new farms and changes to practices by existing farms where they occur in wildlife protected areas. A FIFG-funded project has been carried out by Seafish which focuses on Pacific oyster cultivation in and around European Marine Sites. Working closely with industry and statutory nature conservation agencies, relevant background information was collated (Development of a Pacific oyster aquaculture protocol for the UK - Technical Report and a protocol proposed (Development of a Pacific oyster aquaculture protocol for the UK - Protocol template. Where there could be an impact on protected wildlife and/or marine habitats, husbandry and management techniques have been proposed to mitigate or eliminate any potential impacts. The project complements the ‘Memorandum of Understanding for Appropriate Assessments in European Marine Sites’ that was agreed between the SAGB and Natural England.

The mussel culture industry is one of the largest and most valuable fisheries in the UK representing almost 90% of total shellfish aquaculture production by weight in England and Wales with a value of around £14 million per year. Continuing productivity is significantly dependant on the movement of mussel seed from wild settlement areas to cultivation areas. Unfortunately, these shellfish movements can also spread pests such as the non-native slipper limpet (Crepidula fornicata) which has the potential to have a devastating effect on both fisheries and marine eco-systems as it out-competes other species for food and space as well as depositing pseudo-faeces that builds up to create cohesive ‘muds’. An accidental introduction of slipper limpets into the major UK mussel culture area of the Menai Straits, North Wales has recently occurred following a movement of mussel seed contaminated with slipper limpets from the English Channel. This led to urgent remedial action having to be taken by industry which involved removing the infested mussel seed and then smothering of any remaining slipper limpets with new slipper limpet free seed. There is a need therefore for the industry to self regulate and minimise risks in such transfers. Failure to do so will otherwise result in measures being imposed on industry in this respect. Positive action is now currently being undertaken in some regions as can be seen by the development of a Code of Good Practise by the Bangor Mussel Producers.

he Agri-Food and Biosciences Institute (AFBI), Seafish and the Northern Ireland (NI) Scallop Association have recently completed a report investigating the optimal areas for scallop reseeding in the Irish Sea. This work was commissioned due to an increase in exploitation of scallops around the NI coastline and a desire by industry to be proactive in enhancing long-term sustainability of stocks. Sites selected through industry engagement as proposed reseeding sites were examined by AFBI scientists to ensure that they met the characteristics required for successful settlement of scallops. Seabed habitat maps were combined to provide information for the full sea area under consideration. Scallop catches from the annual AFBI scallop survey were mapped with the full habitat map to determine the areas where scallops were present and identify the underlying habitat type. This allowed a map to be created which showed the suitable habitat for adult scallops within NI waters. All of the proposed reseeding sites fell within areas of suitable habitat. To examine further characteristics of the proposed sites, a combination of measured and modelled data was used. Salinity, food availability, bed stress (natural physical disturbance of the seabed by wave action and/or tidal currents), particulate inorganic matter, suspended particulate matter, abundance of predators, spawning season, larval dispersal and hydrodynamic models were all considered. The above information was presented to the project steering group, and using the data provided, the steering group selected the most suitable sites for reseeding from the original 13 proposed sites. Three reseeding sites (Whitehead, Drumfad Bay and South Bay) have initially been proposed, with a fourth, Roaring Rock, having potential for any future reseeding plans. The NI Scallop Association will now present the results of this work to DAERA to ask for regulation to assist in the protection of these new areas through a ban on mobile fishing gear.

This report provides a national strategic overview of the findings and recommendations 2. provided in the 9 IFCA specific Strategic Sustainability Reviews which were the primary focus of Stage 3 of Project Inshore. In addition, the national overview report provides the opportunity to highlight those stocks which straddle the inshore boundary (6nm) and have therefore not been the focus of the IFCA specific reports.

This report presents stage 3 of Project Inshore where findings of stage 1’s data gathering on fisheries within each IFCA and the results of stage 2’s MSC pre-assessment conducted for fisheries around England’s coast (involving over 400 different species, stock and gear combinations) are considered to provide a Strategic Sustainability Review tailored to the Cornwall IFCA
