Ichthyology

Life histories of fishes are studied in rivers. Especially, fieldworks are often carried out to conserve threatened species and aquatic biodiversity.

Research Interests

• Development of support tools for multi-nature river manegement with watershed flood control
  keyword : watershed flood control freshwater fish
  2023.04～2026.03.
• Development of technology to convert land plants into blue carbon
  keyword : Phragmites australis, Miscanthus sacchariflorus, fishing reef, blue carbon
  2020.03.
• Technology development on setting target species using species distribution models in order to restore river ecosystem after a large disaster
  keyword : disaster, species distribution model, environmental DNA, target species
  2019.04～2021.03.
• Study on ecosytem and biodiversity on tidal flats
  keyword : tidal flat, estuary, benthos, salinity
  2012.05～2021.03.
• Study on the domestic alean fishes in Kyushu Island
  keyword : Domestic alean, internal invasion, distribution pattern, prediction on settlement area
  2006.04.
• Study on the structure of aquatic ecosystem
  keyword : agricultural　channel, river mouth, estuary
  2005.04～2021.07In the cleaks around the Ariake Bay in northern Kyushu Island, I investigate the ecosystem of the freshwater fishes. As of now, it is cleared that several threatened species inhabit in the cleaks, and foreign fish species invade their habitats. Forward, I continue to research to conserve native species..
• Study on the healthy evaluation of the aquatic ecosystem in rivers
  keyword : stable isotope analysis, feshwater fish, urbanization
  2005.04In the northern Kyushu Island, I research the relationships among the population of the freshwater fishes and the urbanization of the watershed to conserve the environment of the river ecosystems around the citied areas..
• Study on the distribution, life history, and habitat use of several threatened fishes
  keyword : Threatened fishes, distribution pattern, habitat use, growth, maturity, age
  2005.01～2021.07Cottus pollux is one of the species on the brink of extinction. MOreover, it is not cleared about the distribution and ecology. We investigate the distribution in the north Kyushu, Japan, and study the relationships between water temperature and the habitats..
• Study on the life history of catadromous sculpins
  keyword : Catadromous sculpin, Trachidermus fasciatus, Cottus kazika
  1993.04～1999.03This studies is conducted to be clear the growth, migration, and reproduction of Trachidermus fasciatus and Cottus kazika..

Current and Past Project

• This study will be to clarify the recovery process of aquatic ecosystem in areas with heavy rain disaster.
• This study will develop a technology to set target species using species distribution models in order to restore river ecosystem after a large disaster.
