The Hilsenhoff Biotic Index (HBI) can be a biotic index dependant on species tolerances to natural and organic enrichment (Hilsenhoff 1987, Hilsenhoff 1982); higher HBI scores may possibly point out organic and natural enrichment ample to lower oxygen degrees. Fish communities also change with DO, however the designs are not as very clear as a result of less species as well as a more compact range of tolerance.
