Experimental Study on the Fish Preference for Hydraulic EnvironmentsPublished by the American Society of Agricultural and Biological Engineers, St. Joseph, Michigan www.asabe.org Citation: Paper number 027004, 2002 ASAE Annual Meeting . (doi: 10.13031/2013.10305) @2002Authors: Kazuaki Hiramatsu, Shiomi Shikasho Keywords: Preference intensity model, Japanese Medaka Fish, environmental factor, laboratory experiment
The preference intensities of river fish to environmental factors were discussed in this paper. The
three environmental factors of water depth, current velocity and cover were selected as the principal factors
affecting the availability and quality of the fish habitat in natural rivers. Japanese Medaka Fish (Japanese
killifish, Oryzias latipes) was selected as a river fish subject to quantify preference intensities because
Japanese Medaka is now regarded as the symbolic fish for the restoration of countryside ecosystems in Japan.
