Case studies

The progress towards DEEPFISHMAN objectives will be developed by examining a range of case studies selected to reflect the diverse characteristics of the different types of deep-water fishery found in the NE Atlantic. In addition two case studies outside the NE Atlantic and Mediterranean Sea are included to give a wider perception of the management and monitoring of deep-water fisheries elsewhere in the world. These studies will include an ICPC country: Namibia. Fisheries data (including all bycatch data) from case studies will be used to examine historical catch data for changes in biodiversity and to identify protocols for monitoring biodiversity (of both vertebrates and invertebrates) in the deep-water ecosystem. The socio-economic profile and projected socio-economic impact of the management strategy options will be examined for selected case studies. The objectives of each case study are :

  • To review the historical development of the fisheries and to describe the main characteristics of the fleets currently involved.
  • To review the biology, ecological and other information currently available on biological parameters, including data collected on stock assessment surveys.
  • To review and collate the fisheries, biological, biodiversity, Vulnerable Marine Ecosystems (VMEs) and socio-economic data, and information currently available for management and monitoring purposes, identifying strengths and weaknesses, and to identify any existing data/information not used or not fully used at present. Collated fisheries data will include all bycatch data, including other commercial and non-commercial fish species, corals, sponges and other benthos, seabirds, marine mammals and turtles.
  • To review the known and likely impacts of deep-water fishing on biodiversity and to inventory and collate data on biodiversity and habitats. To identify missing data and knowledge of biodiversity, which would be required to assess biodiversity and the impact of fishing in the Case study area.
  • To review the current and historical management and monitoring procedures/methods (including assessments, biological reference points, harvest control rules, measures to protect and conserve biodiversity (e.g. technical measures, Marine Protected Areas)) and status of stocks, and to identify possible improvements in the current management and monitoring framework by making better use of data currently available.
