2002 Report

Open River Length Distributions

Length distributions (length) as a percentage of catch (percent) for selected species of interest collected by the Long Term Resource Monitoring Program. Fish species are listed in phylogenetical order following Robins et al. (1991) nomenclature. In some instances, meaningful biological interpretation of these distributions may be limited by small sample size or size selectivity of the gear (Anderson and Neumann 1996). Some fish histograms with small sample sizes (<100) are included because of local interest, while others were omitted (reach dependent). Scientific names for the species listed can be found in Table 1.

Figure*	Species	Method
2.5	Gizzard shad	Electrofishing
3.5	Common carp	Electrofishing
4.5	Smallmouth buffalo	Electrofishing
5.5	Smallmouth buffalo	Hoop netting
6.5	Channel catfish	Electrofishing
7.5	Channel catfish	Hoop netting
10.5	White bass	Electrofishing
11.5	Bluegill	Electrofishing
12.5	Bluegill	Fyke netting
13.5	Largemouth bass	Electrofishing
14.5	White crappie	Fyke netting
16.5	Sauger	Electrofishing
18.5	Freshwater drum	Electrofishing
19.5	Freshwater drum	Fyke netting
*Figure numbers are not always in sequence because some species were not caught in some study areas. Figure numbers for each species and gear type are consistent among study areas.
