Ever wonder what fish are swimming beneath the surface of Indiana’s lakes? So do we!
Each year, DNR fisheries biologists survey Indiana’s natural lakes as part of the Fisheries Status & Trends Program. Since 2010, biologists have looked at fish communities, water quality, and aquatic habitat at more than 100 lakes across Indiana. These surveys generate long term data on common species like bluegill, largemouth bass and yellow perch, and lesser known native fish such as bowfin, spotted gar, lake chubsucker, and yellow bullhead. Altogether, the program has identified the location and presence of more than 60 fish species in Indiana’s lakes.
This summer, biologists will continue to survey lakes across multiple Indiana counties to monitor year to year changes in native fish populations and habitat quality. Each survey provides valuable information that helps resource managers protect clean water, conserve diverse native species, and maintain high quality fishing and outdoor recreation for future generations.
