Title: Review Panel Comments June 2006


1
Review Panel CommentsJune 2006
  • 2005 Accomplishments and 2006 Plans
  • Overall progress
  • Response to 2005 Review Panel recommendations
  • Sport fish sampling and advisory development
  • Biosentinel sampling and mercury in the food web
  • Risk communication/education and SH involvement
  • Project management
  • Investigators questions
  • Overall recommendations

2
2005-2006 Progress
  • Considered and acted on recommendations from 2005
    Review Panel meeting.
  • High level of positive energy among researchers,
    steering committee, stakeholders.
  • on project implementation for first year.

3
2005-2006 Progress
  • Excellent reliability of analytical data strong
    internal QA program increases value of data,
    particularly for historical/comparative purposes
    inter-lab comparisons are strong.
  • Strong focus incorporated throughout on
    environmental justice concerns and community
    outreach.
  • Excellent coordination (e.g., DHS OEHHA OEHAA
    DFG).

4
2005-2006 Progress
  • Positive and active interaction with
    stakeholders project activities have been
    modified to address SH concerns and needs.
  • High quality reports, summaries, presentations of
    data.

5
Response to Prior Panel Recommendations
  • Explored existing data sets and implications for
    current study (e.g., sampling).
  • Sample site selection informed with data about
    where people fish, data needs for advisory
    development (v. good coordination), etc.
    (impressive Matrix).
  • Examined relationship of mercury mining to
    contaminant locations (clarify source concerns,
    e.g., mining vs. atmospheric).

6
Response to Prior Panel Recommendations
  • Power of statistical tests addressed well for
    biosentinels.
  • Thoughtful approach to individuals vs. composites
    for biosentinels.
  • Developed Matrix for sport fish site-selection
    purposes.
  • Evaluate whether criteria should be further
    refined for accepting some sites and rejecting
    others (e.g. further refine quality of fishing
    pressure data how other criteria are scaled).

7
Response to Prior Panel Recommendations
  • Train-the-trainer appears to be good approach.
  • Strong engagement of CBOs mini-grant program
    very good for future, develop other funding
    sources?

8
Response to Prior Panel Recommendations
  • Good efforts re regional perspective on data for
    advisories.
  • Continue considering whether Safe Eating
    Guidelines can be simplified further based on
    trends found.

9
Response to Prior Panel Recommendations
  • Clarified focus on methylmercury, yet pursuing
    other organics funding.
  • Using adaptive approach (e.g., white catfish,
    Greenville Rancheria, non-traditional species
    such as Asiatic clams biosentinel site selection
    vis-à-vis RR) --but need to document better.
  • Safe Eating Guidelines include health benefits,
    commercial fish, avoid larger fish.

10
Response to Prior Panel Recommendations
  • Effort made to relate biosentinel site selection
    to sites from other studies focusing on
    fish-eating birds, other avian species, to better
    understand forage and trophic level processes
    could be demonstrated/documented better in
    written report.

11
Response to Prior Panel Recommendations
  • Analyzing samples in timely manner to inform
    future decisions.
  • Communication between FMP and other regional
    projects good look for ways for further
    improvement esp. in linking study results.
  • Progress made on identifying end users and their
    information needs, and decisions to be made based
    on these data -- but could be improved and made
    more explicit.

12
Response to Prior Panel Recommendations
  • Continue to articulate who audiences and
    decision makers are to whom information should
    go, and what they will do with it. (Revisit re
    what decisions will be made based on project
    data.)
  • Continue to consider what will be reported and
    on what schedule, particularly related to project
    goals.

13
Sport Fish Sampling and Advisory Development
  • Emphasis on health and consumption advisory
    aspects of sport fish data is appropriate given
    goals of project.
  • Consider sampling and analysis to include size
    ranges to develop advisories based on size.
  • For advisory development, length vs.
    concentration is important for some species but
    not others (e.g., not for white catfish).
  • Aging of fish (at same size, age may differ, may
    relate to environmental variables).

14
Sport Fish Sampling and Advisory Development
  • Need to summarize and present/use organics data
    that are already available.
  • What is the connection between OEHHA/DHS matrix
    vs. SFEI historical data base? Were the SFEI fish
    contaminant data used by OEHHA? (clarify data
    sources and uses in written report)

15
Sport Fish Sampling and Advisory Development
  • Examine data that are not corrected for
    differences in length-weight relationships
    examine fish concentrations standardized by
    linear regressions and confidence intervals based
    on regressions. Compare with Tremblay analysis.
  • In Tremblay analysis, evaluate robustness of
    technique given sample size, differences in
    length-weight relationships, and other
    assumptions. (Concern with Type I error.)
  • Data tables should show sample size (n) e.g.,
    Figure 12 in Year 1 Annual Report Sport Fish
    Sampling and Analysis.

16
Sport Fish Sampling and Advisory Development
  • When explaining Tremblay ANCOVA data to other
    SHs will be difficult.
  • Endorse removing white catfish from ANCOVA
    analysis.
  • Consider predictive abilities for
    hypothesis-generation and future sampling
    decisions
  • Reservoir management/operation
  • Thermal stratification, anoxia
  • Use reservoir data to guide selections for future
    sampling

17
Sport Fish Sampling and Advisory Development
  • Articulate explicitly what criteria were used to
    select the reservoirs for sampling clarify if
    selection was based solely on Matrix elements in
    future, consider using predictive capability
    especially from regional data (e.g., SWAMP data).
  • Striped bass sampling likelihood low for
    meaningful results from sex analysis for mercury
    also for organics if composites are used.
    Other factors may be important (age, amount of
    time in Delta vs. ocean, trophic position, etc.)
    consider them in final design.

18
Sport Fish Sampling and Advisory Development
  • Develop hypotheses e.g. potential
    biogeochemical mechanisms re Central Delta
    observations photodemethylation microbial
    demethylation biodilution in high-productivity
    waters, etc. to help interpret results, and pose
    possibilities for future studies.
  • Consider other hypotheses ecosystem processes
    (e.g. tidal flooding, biogeochemistry) related to
    mercury changes?

19
Sport Fish Sampling and Advisory Development
  • Articulate clearly to stakeholders and funding
    agencies what would be needed to observe real
    trends in sport fish mercury concentrations.
  • Include sites that address possible behavior
    changes for anglers (e.g., if reservoirs have
    high concentrations, what are alternative
    locations above and below reservoir?).

20
Education and SH Involvement
  • Consider ways to gather more information on
    indicators of potential for human exposure, e.g.,
    through creel surveys or other surveys (e.g.
    BRFSS) to add in pertinent questions (fish
    consumption who is eating, how much, what
    species, etc.).
  • This would help risk communicators understand
    scope of exposure issue as well.

21
Education and SH Involvement
  • Post sampling maps on web site color and
    black/white versions.
  • Continue plans for multiple focus groups within
    cultural groups.
  • Continue train-the-trainer approach, and building
    capacity within CBOs and communities. Explore
    methods to make this self-sustaining over time.
  • Good consideration of politics (e.g., 1 site per
    county) for buy-in.

22
Education and SH Involvement
  • Document approaches used for community engagement
    what has worked and why, what has not worked
    to help inform future efforts in FMP and other
    projects.

23
Education and SH Involvement
  • Include formative evaluation (during development
    of materials and distribution methods) as well as
    summative evaluation (outcomes and impacts of
    risk communication on awareness, attitudes, and
    behaviors).
  • Qualitative data are better than no data, and can
    be cost-effective in terms of evaluation.

24
Mercury in the Food Web (Biosentinels)
  • Keep ecosystem-level framework in mind re
    mercury behavior within system
  • Strive to identify and understand factors
    controlling contamination of food webs and edible
    fishes concentrate on ecosystem restoration
    criteria as principle emphasis.
  • Articulate how the work of FMP has contributed to
    understanding of the system, e.g.
  • San Joaquin being different from the Central
    Delta region?
  • How has FMP contributed to interpretation of
    historical data?
  • How can FMP contribute more? (include a category
    in report What have we learned? What else
    should be addressed that is not yet being
    addressed? Suggest future hypotheses.)

25
Mercury in the Food Web
  • Keep major FMP goals mission in mind when
    making adaptive biosentinel sampling
    decisions/changes
  • - place primary emphasis on evaluating effects of
    ecosystem restoration on MeHg contamination of
    aquatic food webs.
  • - assessing potential trophic transfer of MeHg to
    wildlife.

26
Mercury in the Food Web
  • Consider dropping redundant and monotonous sites
    to add those of more interest for scientific (or
    management) questions.
  • Clear use of hypotheses and research questions
    to guide work to date use this same approach in
    making adaptive decisions re changing protocol,
    sites.

27
Mercury in the Food Web
  • Outliers demonstrate consequences of decision
    to exclude from calculation of means attempt to
    explain why they exist, and patterns in
    occurrence.
  • Consider examining diet differences in
    silverside early cohort vs. late cohort to help
    explain differences.

28
Mercury in the Food Web
  • Body burden -- Biosentinel data are now
    presented as whole-body concentrations of total
    mercury. Consider also reporting biosentinel data
    as burden of mercury, a direct estimate of the
    mass of methylmercury accumulated during the life
    of the biosentinel organism. These data could
    provide insight into seasonal patterns of mercury
    uptake and contamination of young fish.
  • Consider following same silversides cohort
    through over time re seasonal analyses?

29
Mercury in the Food Web
  • Suggest background levels of mercury based on
    available data relate to issue of atmospheric
    deposition vs. mining issues, and what future
    conditions are realistically achievable.

30
Mercury in the Food Web
  • Stations have been selected to show regional
    differences, but consider similarities in systems
    and use these system-level characteristics to
    develop hypotheses and evaluate ability to
    classify these systems (e.g., seasonal and tidal
    flooding salinity levels, etc.).
  • SFEI modeling should be driven by these (and
    other) hypotheses.

31
Mercury in the Food Web
  • Consider ecotoxicologial relevance
  • biologically-significant shifts in
    concentrations?
  • spatial influence of a restoration project
    (localized effects vs. system effects)?
  • implications for reproductive effects on fish?

32
Mercury in the Food Web
  • Continue, and increase as appropriate, efforts
    to work with ecosystem restoration groups
    (restoration program agencies), for adaptive
    management purposesnot just adaptive research,
    adaptive management and on-the-ground restoration
    activities Document efforts.
  • Good application of weight-of-evidence approach
    (e.g., multiple species comparisons). Include
    comparisons with data from other projects (e.g,
    aqueous MeHg concentrations).

33
Mercury in the Food Web
  • Keeping focus on ecosystem-oriented linkages will
    be important
  • biogeochemistry
  • coordination with other groups especially other
    CAL-FED projects
  • developing hypotheses
  • using data to make predictions.

34
Project Management
  • Need for additional funding (risk communication,
    EJ efforts, organics, to explore future
    hypotheses). Good efforts thus far.
  • Make suggestions re standardized data reporting
    for all projects into future (e.g., merging
    fishing activity with other data sets consistent
    labeling of study sites on maps, lists etc.).

35
Project Management
  • FMP has diverse array of products (e.g.,
    education materials, databases, etc.). Develop
    means for these to remain accessible after
    project ends.
  • Maintain and update database throughout project.
    Will assist inter-investigator communications.

36
Investigators Questions
  • How to best demonstrate addressing short-term
    goal of reducing human exposure?
  • Identify indicators of potential reduction in
    human exposure (e.g., awareness of contaminant
    situation awareness of Safe Eating Guidelines
    behavioral intentions behavior change fish
    consumption, fishing locations). Tie in to other
    survey efforts.
  • Evaluate effectiveness of specific communication
    materials/efforts.
  • Next step biomonitoring of human exposure --
    is human exposure declining?

37
Investigators Questions
  • Striped bass sampling? (answered earlier)
  • New approaches to advisory development and
    content?
  • Consider size relationships use of regressions
    to developed size-based advice vs. means analysis
    when no size relationship.
  • Consider increasing regional approaches.
  • Attempt to move away from segmented
    (site-by-site) release of Safe Eating Guidelines
    to more coordinate statewide release of
    information.

38
Investigators Questions
  • Suggested goals for bioaccumulation modeling
    factors to consider?
  • Should be hypothesis-driven as discussed earlier.
  • Primary use of model should be to address
    hypotheses and do sensitivity analyses.

39
Investigators Questions
  • Big picture for sport fish sampling plan?
  • (?) balancing rivers vs. reservoirs dont
    emphasize run-of-river reservoirs (low retention
    time) select reservoirs with longer residence
    time, higher productivity, that stratify to
    anoxic conditions.
  • (?) sampling criteria (how best to make
    decisions between water bodies) see earlier
    comments re refining Matrix criteria.

40
Investigators Questions
  • Recommended approaches for outreach efforts?
  • Explore additional funding for EJ groups.
  • Explore additional tribal needs/concerns.
  • Continue to engage CBOs.
  • Recommended approaches for evaluation efforts?
  • Evaluate and document effectiveness of specific
    materials and elements of outreach program, by
    community/audience.
  • See earlier comments on formative, summative
    evaluation.

41
Investigators Questions
  • Has Review Panel been given appropriate amount
    and content of materials to review progress and
    plans?
  • Provide additional time for review (1 week).
  • Provide presentation (Power Point) files in
    addition to written reports both in advance.
  • High quality of presentations and reports.
  • Helpful for Review Panel to observe interaction
    with Steering Committee and stakeholders.
  • Consider adding summary presentations from other
    projects related to FMP, to illustrate linkages.
  • Review Panel contributions will only be
    proportional to the information we have in
    advance including documentation of decision.
  • In next report, include specific section on how
    Review Panel comments have been considered.

42
Investigators Questions
  • Revise technical reports now vs. include in next
    years report?
  • Important to synthesize project data as soon as
    feasible.
  • Important to revise sampling plan as soon as
    possible and implement field season.
  • Set realistic deadline to complete synthesis
    report of all 2005 data communicate target date
    and final 2005 report with Review Panel.

43
Overall Recommendations
  • Record explicitly how adaptive approach is being
    used within FMP how 2005 data influence 2006
    decisions, rationale, etc.
  • Maintain ecosystem perspective by considering
    other data being gathered (e.g., water,
    biogeochemistry) look for opportunities for
    cross-fertilization.
  • Develop hypotheses for future studies, and on
    relationships between elements of this project.
  • Consider including summary presentations from
    other, related projects at FMP annual meeting, to
    enhance integration of findings at ecosystem
    scale.

44
Overall Recommendations Data Communication
  • Public consumption of information important
    e.g., keep effort going on lay annual report.
  • Explore needs for available/accessible database,
    in addition to web-based listing at project end
    (especially within FMP and SH groups as project
    continues).
  • Data should be published in refereed journals
    sport fish data, biosentinel data, processes of
    risk communication/public outreach these are
    ground-breaking data and need to be in public
    scientific domain.
  • Documenting adaptive decisions and reasons for
    decisions will be important for both of these
    purposes, and for future researchers.

45
Overall Recommendations Data Communication
  • Continue productive efforts with stakeholders and
    CBOs.
  • Develop holistic sense of remediation and
    restoration projects and relation to FMP
    intensity communication efforts with groups
    involved with ecosystem restoration to develop a
    better understanding of possible ecosystem
    processes.
