Research Topics
  • Research on fishways in rural areas

    The development of fishways to be installed in the irrigation and drainage canals and ditches around paddy fields has been conducted using an experimental channel in the hydraulics laboratory building of the Ishikawa Prefectural University. We are trying to examine the optimum shape of weir to make japanese kitanomedaka (Oryzias sakaizumii), japanese weather loach (Misgurnus anguillicaudatus) and nine-spined stickleback (Pungitius sp.1) around paddy fields ascend, and to reveal their swimming speed at the time of ascending and ascending routes by analyzing the moving images of ascending behavior shot by a video camera in the model experiment.
    In addition, we have verified the function of two experimental pool and weir fishways with orifices installed between a pond and two agricultural waterways, for nine-spined stickleback (Pungitius sp.1, a freshwater fish of the family Gasterosteidae, criticaly endangered or endangered species of Ishikawa Prefecture), by conducting ascending and descending fish surveys using small fixed nets and hydraulic and environmental investigations. Analysis on ascending behavior of nine-spined stickleback (Pungitius sp.1) and the swimming speed by three-dimensional video measurement method (Hydraulic laboratory building of the Ishikawa Prefectural University) Ascending fish investigation in the experimental pool and weir fishway with orifices (Shika-machi, Hakui-gun, Ishikawa, Japan)

  • Research on habitat evaluation for the freshwater type of nine-spined sticklebacks using habitat suitability index

    Research on habitat evaluation for the freshwater type of nine-spined stickleback (Pungitius sp.1) using HSI

    We are conducting a habitat assessment of the freshwater type of nine-spined sticklebacks (Pungitius sp.1) on the basis of the investigation results on population densities and habitat environment in the Kumata River and the Nishi River basins (Nomi-shi and Hakusan-shi, Ishikawa) and the Oko River basin (Shika-machi, Hakui-gun, Ishikawa), using the HSI (Habitat Suitability Index).
