CDFW in collaboration with the fishing and conservation community continues working to develop a Fishery Management Plan (FMP) for Pacific herring in California. Please check out the Pacific Herring FMP Web Page for more details and to view the anticipated timeline for completion. Please also stay tuned for more opportunities for involvement with FMP development later this summer.
