Information is critical to Ecosystem Approach and to research about Vulnerable Marine Ecosystems/Habitats (VME/Hs), fishing impacts on habitats and ad-hoc management measures are high-priority. Therefore, this paper presents the ECOVUL/ARPA Interdisciplinary Approach, a case study of methodology for the identification of VME/Hs in order to advise on conservation measures such as marine protected areas (MPAs). By means of an interactive process involving Conventional Fisheries Science, Geomorphology, Sedimentology and Benthic Ecology, the methodology developed under the ECOVUL/ARPA project, has been useful in order to contribute to define practical criteria to the identification of VME/Hs, to improve the knowledge about VME/Hs distribution and the adverse impacts of bottom trawl fisheries and to produce high quality advice on habitat protection. Applying an interdisciplinary approach, the project identified the deep-water bottom trawl fishery footprint on the Hatton Bank Western slope (NEAFC Regulatory Area), mapped the main fishing grounds and related seabed habitats and studied the interactions between fishing and cold-water corals. This approach was used to suggest, with high level of precision, the spatial limits of an area closed to bottom fishing, as an essential conservation measure to protect the cold-water corals in the framework of the Ecosystem Approach to Fisheries management. We present here the methods used, the main results obtained and discuss on the utility of this approach and the possibilities to apply it in the NAFO Regulatory Area, with the aim to advise on measures for reducing the interactions of bottom fishing with sensitive high-seas habitats and to contribute to implement the UNGA recommendations about habitat conservation.
