Mean catch-per-unit-effort and (standard error) for fish collected by mini fyke netting in La Grange Pool of the Illinois River using stratified random sampling during 2000. The statistics under ALL pertain to unbiased means over all strata sampled by this gear (as indicated by nonmissing entries below and by Table 2.6). See Methods for definitions of catch-per-unit-effort and standard error. Scientific names for the species listed can be found in Table 1. |
