A Pilot Program for Monitoring, Stakeholder Involvement, and Risk Communication Relating to Mercury in Fish in the Bay-Delta Watershed(aka “The Fish Mercury Project”)
SFEIUC Davis
CDFG DHS/EHIB
OEHHA
Funding provided by CBDA
Presented at the 2006 Mercury Coordination Meeting
How can we minimize methylmercury exposure?
Longer Term Solution for Humans and Wildlife• Adaptive management of water quality and
restoration (actions and monitoring)• Tracking regional trends in biotic exposure• Tracking local trends near restoration and cleanup
projects
Shorter Term Solution for Humans Only• Identify high and low areas and species• Develop consumption advice• Communicate risk information to the public
Risk Commun-

Project Elements
Year 1 Sampling Plan
• Steering Committee input• Review Panel input• Discussions with restoration managers• Close coordination with other major programs• Fishing activity information• Review of historical sampling• Detailed tables (“matrices”) documenting site
selection
Sport Fish Sampling, 2005Type of Site Description Index Evaluating the potential regional impacts of
habitat restoration in the Delta Intensive Another type of index site where more
detailed investigation of temporal variation and mercury movement through the food web will be conducted
Restoration and Remediation
Evaluating the localized impacts of CBDA habitat restoration and remediation projects on food web mercury
Advisory Development
Providing the data needed to support consumption advisory development for the CBDA ecological management units
Sport Fish Sampling, 2005
Sport Fish Sampling, 2005
Sport fish species sampled (# sites)• largemouth bass (47)• white catfish (24)• striped bass • Sacramento pikeminnow (17)• Bluegill (34)• redear sunfish (40)• common carp (25)• Sacramento sucker (29)• channel catfish (25)• black crappie (11)• black bullhead• pumpkinseed• Sacramento perch
• rainbow trout• hitch• smallmouth bass • spotted bass• chinook salmon• Steelhead
• About 1600 fish collected
• 66 sites total (including Foe study and SRWP)
• 7 hatcheries
Biosentinel Sampling (UC Davis)
Biosentinel Sampling, 2005
• Also a few restoration sites further up in the watershed
• About 10,000 fish collected in 2005
Advisory Development, Years 1 – 3 (OEHHA)
• Linked with sport fish sampling, but primarily based on existing data
• Year 1 – south Delta, San Joaquin River, Cosumnes River and Mokelumne Rivers and associated reservoirs, Feather River
• Year 2 – north Delta, Sacramento River, Lake Shasta, other tribs and reservoirs in the Sacramento River watershed
• Year 3 – Tributaries, creeks, and reservoirs in the San Joaquin River watershed
• Advisories to be developed using an established protocol
• Advisory development workplan will undergo peer review
Stakeholder Involvement and Risk Communication, Years 1 – 3 (DHS – EHIB)
• Linked with sport fish sampling and advisory development• Stakeholder and risk communication workplan will undergo
peer review• Includes evaluation of effectiveness
Stakeholder Involvement, Years 1 - 3
• Fishing activity evaluation (prior to sampling each area)• Contact county health agencies• Contact DFG wardens and other fishing experts• Site visits• Focus groups
• Needs assessments: interviews, focus groups, surveys – focus on risk communication
Risk Communication, Years 1 - 3
• Communicate with community leaders (fact sheets, newsletters)
• Educational materials and activities (multi-lingual)• Posters, cards, fact sheets• Mini grants to CBOs• Delta advisory sign
• Training – building local capacity• Forum on fish contamination and
public health held in December 2005
• FMP Annual Meeting on June 13 and 14• Joint meeting of Steering
Committee and Review Panel (Knuth, Wiener, Bodaly, Grieb, McCann)
• Results of 2005 sampling• Plans for 2006 sampling • Progress and plans: advisory
development• Progress and plans: fishing activity
assessment, risk communication• Annual technical report
