north devon case study dr olivia langmead marine biological association
TRANSCRIPT
Focus of the study• Subtidal sediment habitats and
their value in supporting fisheries production
• The valuation research will consider the role of sediment habitats as nursery areas and in sustaining food chains (food supply for fish)
• Scenarios will be developed (with you!) to determine how values might change under different plausible management scenarios
• We anticipate that this work will be of direct benefit for the long term management of the area
Data collectionData have been collected on: Human activities and uses
that affect the seabed – their distribution and intensity in the NDBR marine area
Ecology – seabed species and habitats, nursery and spawning areas for commercially important fish species and reported catch
Management – existing measures including MPAs, fisheries restrictions
Human activities that leave a footprint on the seabed: Fisheries
(5) VMS data still to

IFCA potting surveys
RWE potting and trawl surveys
• These maps show what we know about– human activities– Ecology –Management
• Do they match up to the real life situation?
• What are we missing?• How can our understanding be
improved?
