A versatile and economical method for collecting macroinvertebrates using Hester-Dendy multiplate samplers

Environ Monit Assess. 2023 Nov 10;195(12):1453. doi: 10.1007/s10661-023-12058-z.

Abstract

We present an inexpensive, versatile, and robust mounting system for Hester-Dendy (HD) multiplate samplers that are useful in aquatic biological studies and freshwater biomonitoring programs. Detailed instructions are provided outlining the construction and deployment of a concrete block system featuring threaded anchors for screwing in HD columns in a vertical position. Additionally, eye bolts provide a central attachment point for cabling the block securely to the stream or river bank, and for attachment of a buoy or physiochemical data logger if desired. All the components of the block system are inexpensive, readily available, and assembled with no special skills required. The system offers superior ease-of-use and a more standardized sampling device compared to other methods.

Keywords: Artificial substrate; Benthic sampling; Bioassessment; Coarse woody debris.
