ABSTRACT

The Long Term Resource Monitoring Program (LTRMP) completed 1,994 collections of
fishes from stratified random and permanently fixed sampling locations in six study
reaches of the Upper Mississippi River System during 1993.  Collection methods
included day and night electrofishing, hoop netting, fyke netting (two net sizes), gill
netting, seining, and trawling in select aquatic area classes.  The six LTRMP study
reaches are Pools 4 (excluding Lake Pepin), 8, 13, and 26 of the Upper Mississippi River,
an unimpounded reach of the Mississippi River near Cape Girardeau, Missouri, and the
La Grange Pool of the Illinois River.  A total of 62 78 fish species were detected in each
study reach. For each of the six LTRMP study reaches, this report contains summaries of:
(1) sampling efforts in each combination of gear type and aquatic area class, (2) total
catches of each species from each gear type, (3) mean catch-per-unit of gear effort
statistics and standard errors for common species from each combination of aquatic area
class and selected gear type, and (4) length distributions of common species from
selected gear types.
