Presentation given DGMARE Fisheries Science seminar. 24 June 2022. As the knowledge base develops, you must also transform the system that creates, shares & uses that knowledge base. The presentation uses examples to show: 1. Overviews & assessment of risk, provide context to specific challenges 2. Account for dynamic fisheries in social-ecological system 3. Wider participation in developing tools, e.g. maps for spatial advice 4. Progress science under plurality of management objectives

1. ICES advice - incorporating ecosystem based
considerations

2. Challenge of EBM... a suite of management objectives

3. FAO implementation monitoring tool

4. What is ICES doing?
Use of regional
overviews, & evaluation
of risk to prioritise &
frame key findings

5. Local & regional priorities for management
Ecosystem overviews set context, prioritise ecological & management challenges in
each ecoregion, informed by assessments of risk

ecological & politically defined

6. Fish & fisheries
don’t operate in
isolation
Where necessary
account for dynamics
& challenges of
fisheries in social-
ecological system

7. Fish & fisheries don’t operate in isolation
Incremental implementation of new approaches to science & fisheries advice
• 73% of data rich stocks incorporate an element of ecosystem variability
• Estimates of pretty good yields are provided for fisheries management plans
• Mixed fisheries scenarios are provided for trawl fisheries in 3 ecoregions
• Using fish to track trends in marine biodiversity, food webs, & climate change
• Advice for Irish Sea fisheries responds to changes in ecosystem
productivity

8. Challenges - Baltic Sea
We know when fish stocks are below reference points.
Can we manage other pressures & set ecosystem reference points?

9. Working with people & accounting for space
Wider participation in processes & interactive tools for spatial advice

10. Working with people & accounting for space
Increase in participatory development of mapping tools & format of advice,
e.g. impact of bottom trawling on seafloor
Conservation solutions through
spatial optimisation
2013 to 2018
yellow = all trawling
orange = 90% trawling

11. ICES works to reconcile
plurality of management
objectives
Providing science in the
absence of agreed or
comparable management
objectives, while coping
with paucity of data
Example Bycatch Roadmap

creates, shares & uses that knowledge base
• Overviews & assessment of risk, provide context to specific challenges
• Account for dynamic fisheries in social-ecological system
