Workshop to evaluate regional benthic pressure and impact indictor(s) from bottom fishing



What makes a good indicator for evaluating a bottom fishing footprint and impact on broad-scale benthic habitats?

​​​​​​​​​​​​​​​​​​​This workshop (28 February – 3 March 2017) will build on earlier ICES work​ on an EU request for guidance on how pressure maps of fishing intensity contribute to an assessment of the state of seabed habitats (advice and workshop report)​.

Maps of seabed habitat will be combined with those of fishing intensity for assessing the state of seabed habitats. Using a suite of methods, the workshop will prepare examples (e.g. Baltic Sea, North Sea, and Celtic Sea) at the scale of MSFD (sub)regions to include area impacted by bottom fishing. The workshop will look at how the overall modelled impact indicator scores differ and use ground truth datasets where possible. Evaluation will also take place on what constitutes a good indicator in the context of the MSFD for assessing Descriptor 6 (D6) on seafloor integrity and Descriptor 1 (D1) on habitats.

Proposed indices from WKBENTH will be used to demonstrate trade-offs between benthic impacts and fisheries landings or revenue in another ICES workshop WKTRADE ​at the end of March. To ensure the work remains relevant in a management context and supports ongoing work of the Regional Sea Conventions, a stakeholder workshop (WKSTAKE) will be held on 23 March.
