Abstract

Methods for sampling and preparing, and a pictorial key to freshwater Amphipod (Arthropoda: Crustacea) were given. To date, nine species of freshwater amphipods from Hokkaido have been recorded. Amphipods are thought to be useful as an educational tool in the assessment of freshwater environments in Hokkaido. An example of an observation on the assessment of freshwater environments was presented.
