Macroinvertebrate Collection in Streams

Dr. Kelly Johnson, Associate Professor, Ohio University Biological Sciences, describes methods and equipment needed to collect aquatic macroinvertebrates from wadable streams. Macroinvertebrates found in streams are good water quality indicators of stream health. The kick and dip net methods described can be used for calculating, the Macroinvertebrate Aggregated Index for Stream (MAIS), a family-level biotic index used for scoring stream health in the Appalachian region.
