  • The Leptobotia curta, known as the Ayumodoki in Japanese, is a Japanese endemic freshwater fish that has been designated as a national treasure since 1977. This fish is, however, categorized as a "critically endangered species" by the Ministry of the Environment's Red Data Book in Japan. While a direct reason of population decline of the Ayumodoki is plausibly land use development and corresponding water pollution in Kameoka City in Kyoto Prefecture, the habitat of the Ayumodoki, we posit that people's unawareness of its value plays a critical role. The objective of this research is to measure economic value (willingness-to-pay) of the Ayumodoki, which people cannot recognize in their daily lives, and to delve into the structure of the economic value for the Ayumodoki, addressing the role of river water quality, conservation activities, and conservation of paddy rice fields. Specifically, we used a choice-type conjoint method in which we first conducted a questionnaire survey among residents of Kameoka city and then demonstrated statistical analyses of the collected data. Our results showed that the economic value of the Ayumodoki was $0.04 by one fish. This means that the economic value of 500 fish (the minimum population required to sustain its population size) for all 37,852 residents in Kameoka City was $0.78 million. We concluded that this value calculated for the Ayumodoki can be used as evidence for the validity of spending a certain amount of public funds on their conservation.
