Pool 4, Upper Mississippi River 2000 Fish Collection Summary
This report is a bullet summary of the Long
Term Resource Monitoring Program's fish collection efforts conducted
by the Lake City
Field Station on Pool
4, Upper Mississippi River during 2000. Information on changes in
fish catch over all years can be obtained from the Graphical
Fish Database Browser.
- 377 fish collections were conducted using 10 gear types (Table
2.1).
- Gear allocations among strata remained consistent for all three sampling
periods, except for one fewer minnow fyke net during period
1 (Table 2.1).
- Water levels did not affect sample allocations (Table
2.1; Figure 1.1).
- Of the 377 fish collections, 324 were from randomly selected sites. Fifty-three
collections were made at fixed sites.
- Side channel borders, backwater contiguous shoreline, backwater contiguous
offshore, and main channel border, unstructured, received the most sampling
effort (Table 2.1).
- 118,789 fish were collected representing 67 species and 3 hybrids
(Table 3.1).
- Historical fish distribution records for the Upper Mississippi River
(Pitlo et al. 1995) document 99 fish species from Pool 4.
- No exotics, threatened, or endangered species were noted (Table
3.1).
- Mean catch-per-unit-effort and standard error for fish collected
by gears using stratified random (Tables
4.1-12.1) and fixed-site sampling (Tables
14.1-21.1) for each stratum are shown.
- Length distributions for selected species of fish are shown in Figures 2.1 to 19.1.
