PMEP, the Pacific Lamprey Conservation Initiative, and the California Fish Passage Forum just published a new report, Barriers to tidal connectivity for native lamprey species, which documents what we know about lamprey species and how they interact with barriers to tidal connectivity. The report was commissioned in 2019 to fill data gaps identified at the October 2019 Barriers to Tidal Connectivity Workshop. The report was written by Dave Ward of Fish Forward.
