This data layer is a Fish Index of Biotic Integrity (IBI). It was developed by the Minnesota Department of Natural Resources. A Fish IBI is a biologically-based, consistent method for determining the integrity of fish populations/communities/assemblages in Minnesota lakes. This IBI combines a number of metrics based on the fish assemblage's taxonomic and trophic composition and the abundance and condition of fish. Such multiple-parameter indices are necessary for making objective evaluations of complex systems and biological communities.
