Section 5.Review of known and likely impact of the fisheries on deep-water biodiversity and VMEs5.1.Previous and current studies of biodiversity5.1 Please list below all previous and current studies of biodiversity in the area inhabited by your stock and append time-series data used. General reviews of the impact of fisheries on deep-water biodiversity and VMEs have been carried out by the Regional Seas Programme of the United Nations Environment Programme (UNEP), the Food and Agriculture Organsiation (FAO), the International Union for Conservation of Nature and Natural Resources (IUCN), ICES and a number of NGOs. A review of work from these organisations is given below. One major impact of deep-water fisheries on deep-water biodiversity is the impact of VMEs and bio-ingeeners species forming 3-dimensional structures. The main of which is Lophelia pertusa but a number of other cold water coral species are recorded worldwide and in the Case study area. The impact of deep-water fisheries on these VMEs is being analysis by the EU coralfish project. 5.1.1.ICESICES work on the deep-water environment is mainly synthesised in report of the ICES-NAFO joint Working Group on Deep-water Ecology. Imapct of fisheries on cold-water coral and sponges have been central to the activity of WGDEC over recent years. WGDEC has also review most (if not all) available data and publiscation relevant to case study 2. 5.1.2.IUCNIUCN provides assessment of the threat and conservation satus of species and hold the red list now of standard use (http://www.iucnredlist.org/). Deep-water cnidarians from the North East Atlantic have been assessed by IUCN. Currently, only five species of deep-water cnidarian species for the Pacific Ocean were assessed by IUCN and were categorised Data Defficient (IUCN 2010). In an assessment of Ecosystems and Biodiversity in Deep Waters and High Seas, UNEP and IUCN concluded that ""While pollution, shipping, military activities and climate change also threaten marine biodiversity and ecosystems, fishing currently presents the greatest threat." This report give some overview of impact on cold water corals and sponges and review impact on other ecosystem components such as bird and marine mammals. IUU fishing is given a significant contribution to global impact of deep-water fishing in the high seas by this report. 5.1.3.OSPAROSPAR made a review of coral gardens and threat to this habitat type now included in the list of OSPAR habitats. This report list EUNIS habitats where coral gardens occur. Threats according to the Texel-Faial criteria were identified. Coral gardens were assessed to be "Currently threatened. In particular, considering the relatively high fishing pressure in deep waters in the OSPAR area, the probability of decline and the degree of threat may be higher than in other oceans" (OSPAR Commission 2010b). 5.1.4.FAOFAO have been involved in managements of deep-water fisheries in the high-seas. Recommendation made for the used of bottom trawling were mainly driven by the impact on deep-water VMEs. 5.1.5.NGOsNGOs have reported impact on VMEs, sometimes based upon published scientific material. WWF considered that the Darwin Mounds were at immediate risk from bottom trawling based upon High frequency sidescan sonar observations (carried out by Dr. A. Wheeler, Cork) and photographic observations (carried out by Drs D. Masson and D. Billett, Southampton) (Lutter). 5.1.6.Other reviewsThe deepnet study provided a review of the impact of deep-water gillnets on the environment. The main impacts identified by this study was the unaccounted moratlity of fish due to suspected misreporteing and inappropriate gear handling leanding to loose of gears then genratic ghost fishing (Hareide et al. 2005). The study only refered to cold water coral to mention that restricting fishing on cold water coral would limit the amount of flost gear. It is actually likely that fixed gears tend to target VMEs much more than trawlers because (i) on flat grounds, set gears may be destroyed by trawlers and (ii) the higher fish density observd on some VMEs might be of interest to these gears. 5.2.Aims, methods and data used, outcomes and recommendations made of biodiversity studies5.2 Please review each study identifying the aims, methods and data used, outcomes and recommendations made. 5.3.Relationship between biodiversity trends and fishing impactHave any of these studies related biodiversity trends to fishings impacts? If so please review. 5.4.Unexploited biodiversity dataIf biodiversity studies have not been carried out are there any existing data that can be used? Please append. 5.5.The way forward to investigate the impacts of fishing on biodiversityWhat in you opinion would be the best way forward to investigate the impacts of fishing on biodiversity in your stock area? 5.6.Previous and current studies of the condition of VMEs5.6 Please list below all previous and current studies of the condition of VMEs in the area inhabited by your stock. 5.7.Aims, methods and data used, outcomes and recommendations of VMEs studies5.7 Please review each study identifying the aims, methods and data used, outcomes and recommendations made. 5.8.Impacts of fishing on VMEs5.8 Have any of these studies investigated the impacts of fishing on VMEs? If so please describe. 5.9.The way forward to investigate the impacts of fishing on VMEs5.9 If VME/fishing interaction studies have not been carried out are, what in you opinion would be the best way forward to investigate the impacts of fishing on VMEs in your stock area ? 5.10.Data and knowledge availability5.10 Are there any aspects of data and knowledge (quality, temporal and spatial extent, time series, availability, accessibility, flow) that [a] impact on assessments and/or [b] affect your ability to provide timely fisheries advice to managers?
