Abstract
The ecological characteristics of the eight-barbel loach Lefua tokaiensis Ito, Hosoya, and Miyazaki were elucidated. Ecological field research was conducted at two localities: the montane stream of Houraiji and the Arao River of the Toyo River system in the Tokai region of Japan. The two localities showed high population density of L. tokaiensis, consisting of young-to-aged individuals. Loaches were likely to reproduce and migrate both upstream and downstream throughout year. Their lifespan was over 10 years, and loaches of more than ten generations simultaneously lived together. Growth rates slowed down strikingly with increasing age. The montane stream of Houraiji was suitable for the population of L. tokaiensis. The results of this study contribute to the protection of this endangered species.
期刊介绍:
Limnology is a scientific journal published three times a year, in January, April, and August, by Springer in association with the Japanese Society of Limnology. The editors welcome original scientific contributions on physical, chemical, biological, or related research, including environmental issues, on any aspect of basic, theoretical, or applied limnology that present significant findings for the community of scholars. The journal publishes Rapid communications, Research papers, Review articles, Asia/Oceania reports, and Comments.
The aims and scope of Limnology are to publish scientific and/or technical papers in limnological sciences, to serve as a platform for information dissemination among scientists and practitioners, to enhance international links, and to contribute to the development of limnology.
