ICES provides scientific advice and cooperates with authorities on over 240 fish stocks, bycatch, deep sea impacts, and marine protected areas. ICES builds knowledge through fisheries monitoring including catch data, surveys, recreational fishing data, population modeling, and scenario projections. Indicators are becoming more integrated to assess changes in ecosystem productivity and their impacts on fisheries and management targets. Monitoring also covers biodiversity, bycatch, seabed impacts, productivity, distribution shifts, and noise. Transparent decision making uses indicators in databases to close areas to protect vulnerable marine ecosystems working with international authorities. Linking diverse data sources allows exploring trade-offs like economic value from different fishing footprints. Turning monitoring into evidence for societal decisions requires accessible

Observations for fisheries and ecosystem approach
1. Fisheries and ecosystem approach
From variables to indicators to society

2. ICES - a knowledge
provider to decision
makers
Providing best available, scientific
advice & cooperate with
international & national authorities.
Over 240 fish stocks, bycatch advice,
deep sea impact, marine protected
areas and roughly 25 specific
requests per year.
5. Annual surveys Trawl
3 200 per year
55 different ship &
gear combinationsAcoustic
Once institutionalized, becomes much less flexible & innovative
6. Indicators are becoming more integrated
Changes in ecosystem productivity/carrying capacity & its impact on
fisheries and management targets

Exploring scenarios with stakeholders
Process included exploration of
concepts with stakeholders
12. Legitimacy and societal processes
In Europe, reconciling management objectives,
the acceptance of methods, the setting of thresholds &
determining what is good status or
acceptable risk (precautionarity)
are societal decisions.
13. In turning monitoring into the evidence
for societal decisions & management:
• Data must be accessible & translatable
• Information on quality of the data
• Data & systems must be interoperable
• Need for multidisciplinary researchers
• Collaborate with partner organisations
• Researchers provide the evidence but
shouldn’t make the decisions

Assume you want to show how human activity and its monitoring are linked and can ‘help’ each other
Impulsive noise is licenced and monitored by national agencies in cooperation with industry – industry aid in the provision of information to these monitoring efforts – and in turn these data are used directly in the impulsive noise register to provide a picture of noise events, there location and intensity – the pressure of the human activities. This type of operational indicator is a stepping stone to aid marine planners and industry in the potential impact of impulsive noise when combined with other information, such as breeding grounds for marine species.
