Description

As part of the Rush River Assessment Project, benthic macroinvertebrates (organisms without a backbone that live in water and are visible with the naked eye) were collected from 8 locations using Hester-Dendy and Brick-Scrubby artificial substrates. The sampling sites were in watersheds that varied greatly in land use, vegetation, and topography and water quality. When sampling macroinvertebrates usually only one type of artificial substrate is used. The purpose of our research was to determine if there were major differences between the number and type of macroinvertebrates colonizing the two different types of artificial substrates at the various sampling sites. The substrates were set out and collected three times from May - August 2003. The colonization period ranged between 5-6 weeks. There were appreciable differences in the type and number of macroinvertebrates that colonized the two different artificial substrates at the different sites.
