Key CriteriaDeveloping the FMP Sampling Plan

• Historical/existing data
• Data gaps in species
• Geographic coverage
• Adequacy for developing consumption guidelines
• Fishing activity
• Most popular locations and species to fishers
• Target populations

5
Step 1 in Developing Matrix

• Compile existing (historical) data
• Spreadsheets created by SFEI selected relevant
  data from statewide database
• Sample sites, species, number of samples, length,
  mean mercury,samples with organics, mean
  chemical concentrations

6
Existing DataMatrix
7
Existing DataLatitude/Longitude Lat/Longs
8
Step 2 -- Refine Matrix

• Reviewed and coded sample sites for project area
• Management units focus
• Geographic scope secondary
• Outside ERP excluded
• Data already used in advisory excluded

9
Modified Matrix
10
Refine Matrix - cont.-

• Applied OEHHA criteria
• Advisory (sport fish) species
• Size criteria
• Selected samples from SFEI statewide database
• Recalculated mean mercury and length for samples
  meeting criteria

11
Summary Statistics
12
Step 3 Review Apply Data

• Review Existing Data
• Summarized samples by location
• Where do we have sufficient sampling?
• Sample size meetscriteria
• Species sampled
• Geographic distribution

13
Summarized Data
14
Step 4 Create Maps of Historical Sampling Sites
15
Step 5 -- Gather Fishing Information

• List of sampling sites sent to stakeholders that
  volunteered to provide fishing info.
• Maps included
• Asked to indicatewhere they fishand what
  species
• Listed sites and other locations

16
Now the Fun Really Begins

• Received spreadsheets from DHS with fishing info.

• DHS Priority Fishing Sites-051906.xls (119808
  bytes) ReservoirCreelTables.xls(58368 bytes)
  census.xls (210432 bytes) Black Bass.xls
  (97280 bytes) Catfish.xls (155136 bytes)
  OtherSpecies.xls (318464 bytes)
  ForkLength.xls (62976 bytes)

DHS Priority Fishing Sites

• Sacramento River
• Other rivers (American, Feather, Yuba, Napa)
• Lakes, creeks, canals, sloughs, delta
• River mile (RM)
• Fishing pressure (FP)
• Shore fishing
• Species, sources (e.g., DFG, LHO, surveys,)

19
Creel Data Species Summaries
20
Creel Data Anglers Summaries
21
Step 6 - How to Correlate Fishing Info, Data,
Location?

• DHS found hard copies of maps showing river miles

• Compared sampling site maps with RM maps to
  find matching locations
• Added RM to site maps by hand

Step 7 Merge Info.

• Merged DHS fishing priority sites onto one
  spreadsheet
• Added additionalinformation
• Priority sites from otherstakeholders
• Creel data
• Historical data

25
Step 8 - Scored for Priority Criteria

• Criteria modified slightly from last year
• Data Gaps
• Fishing Pressure
• Source
• Shore-based fishing
• Within project area (gt 90)
• (more info more High FP sites)
• Prioritized sampling sites by scores

26
More Fishing Info.Native American Community
Greenville Rancheria

• Fishing locations
• Belden Reach
• Hwy 89/ hwy 70 intersection
• Poe Powerhouse
• Seneca
• Popular species
• Eel, rainbow trout, German brown, Sacramento
  pikeminnow, smallmouth bass, suckers, and
  crustaceans including crawdads, hogermites, etc.

27
Glitches, Hiccups, and Inefficiencies

• Many sites identified by RM,no lat/longs
• Fishing people and communitymembers can not
  providecoordinates or RMs
• Missing FP led to mismatches with DHS
  conclusions
• Need room for adding last-minute input

28
Almost there

Anadromous Species2006 Sampling Plan- Mercury
and Organics -

• American shad (25)
• Sample May-June
• Feather, American, Sacramento rivers
• DFG collected xx from Sac. River
• White sturgeon (15)
• Collect on rivers and in conjunction with DFG
  fishery surveys and/or sturgeon derbiesto be
  less destructive
• Striped bass (100)

30
Sampling Plan for Striped Bass

• Multiple sites, spring fall
• Up to 20 water body areas
• 6 fish per site 3 females and 3 males
• Objective examine effect of spawning by
  seasonal comparisons
• Fewer sites, spring fall OR
• More sites for geographic spread?
