DNR Fisheries Survey Summary

1 survey on file from MN DNR Fisheries. Most recent: 1989-07-25 (Standard Survey).

Top Species by Catch Rate

SpeciesAvg CPUEAvg Weight
Bluegill11.110.18 lb
Yellow Bass9.460.43 lb
Black Bullhead5.670.68 lb
Northern Pike3.851.15 lb
Largemouth Bass3.040.42 lb
Pumpkinseed1.730.23 lb

CPUE = catch per unit effort, averaged across surveys (excludes juvenile shoreline seining). Higher CPUE = more abundant in standardized sampling.

From the 1989-07-25 survey

Northern pike abundance was 5.5 per gill net lift. Average weight of northern pike was 1.5 lbs. Pike reproduction appears good, as the sample consisted of age-classes II+ through V+. Bluegill abundance was 18.9 per trap net lift, which is below the area median. Five percent of the bluegills were 7.0 inches or greater…
