La Grange Pool, Illinois River 2000 Fish Collection Summary
This report is a bullet summary of the Long Term Resource Monitoring Program's (LTRMP) fish collection efforts conducted by the Havana Field Station on La Grange Pool, Illinois River during 2000. Information on changes in fish catch over all years can be obtained from the Graphical Fish Database Browser.
- 544 fish collections were made in La Grange Pool during 2000 using
10 gear types (Table 2.6).
- Gear allocations among strata varied for all three sampling periods
because of low and high water extremes (Table 2.6;
Figure 1.6).
- Of the 544 fish collections, 413 were from randomly selected sites.
One hundred-thirty-one collections were made at fixed sites.
- Two tailwater sites were sampled, La Grange Lock and Dam and Peoria
Lock and Dam; data from both tailwater sites were combined for analysis
(Table 2.6).
- Side channel border and main channel border, unstructured received
the most sampling effort (Table 2.6).
- 90,544 fish were collected representing 62 species and 3 hybrids
(Table 3.6).
- Fish distribution records for the Illinois River (Smith 1979) document
115 fish species from La Grange Pool.
- The LTRMP species total for La Grange Pool before the 2000 season
was 83; a shovelnose sturgeon was collected for the first time during
2000 (Table 3.6).
- Mean catch-per-unit-effort and standard error for fish collected
by gears using stratified random (Tables
4.6-12.6) and fixed-site sampling (Tables
14.6-21.6) for each stratum are shown.
- Length distributions for selected species of fish are shown in Figures 2.6 to 19.6.
