Regional Fishery Management Councils encourage local-
level knowledge in federal fisheries management.
▪ Stakeholders with on-the-water knowledge engaged in process
Participation in the scientific aspects of resource
management typically requires considerable involvement
▪ Cooperative research ▪ Citizen science
Crowdsourcing observations from Council stakeholders
provides an opportunity for many people to share their individual perspectives

Stock assessments can have data gaps or lack real-time data:
Current on-the water knowledge from
stakeholders can be used to:
▪ Ground-truth observed trends ▪ Explain anomalies ▪ Inform projections

- ffshore. This was attributed to
red tide, influx of fresh water, or removal of structure.
Comments indicated that the population decline has been
- ccurring since about 2010.
