Article by Calvin R. Fremling and Gary L. Schoening detailing procedures for making an artificial substrate (or mud bottom/body of water bottom) out of polyvinyl acetate. Fremling and Johnson credited respectively as "Winona State College, Winona, Minnesota, 55987, USA," and "Ashland Chemical Co., Box 340, Grassilli Station, Linden, New Jersey 07036, U.S.A." Abstract: During our research on Hexagenia larvae, we have developed the construction of cheap and inert artificial substrates for bioassays and observation of the behavior of these nymphs. The substrates are made of a flexible plastic material based on polyvinyl acetate. Observation aquariums and bioassay cuvettes are obtained by making a sealed glass enclosure around each substrate with a special glue for glass.
