Ecophysiology of fish
Outline Activities

Fieldworks and rearing studies of fish and shellfish to make use of the facilities of Fishery Research Laboratory located in Tsuyazaki are carried out. Staffs in FRL are charged in summer seminars (exercises for fieldwork and ecology) for undergraduates.
Main studies are as follows:
1) Growth and metabolic scaling of teleosts:
2) Ecophysiological significance of cannibalism of teleosts during early life stage:
3) Conservation and enhancement of fluvial, estuarine and littoral fields:


As the relations with the local areas, I participate in the environmental survay and symposia on ecomanagement in Tsuyazaki Town and Koga City. I also take on a lecturer in ecomanagement seminars by NPO and a commissioner for River Basin Committees of Fukuoka and Miyazaki.
Research
Research Interests
  • Growth and metabolic scaling in fish and shellfish
    keyword : Metabolism, scaling, body size, oxygen consumption, growth, larva & juvenile
    2000.01~2017.03Growth and metabolic scaling of fishes Keywords: scaling, body size, growth, oxygen consumption, larvae, juvenile. Mass-specific metabolic rates decrease with increasing body mass. This phenomenon is well known in animals interspecifically as well as intraspecifically. Teleost fishes are usually born in the smallest body size among vertebrates, and grow up to the large adult size in their own efforts. For example, bluefin tunas hatch in 0.0002 g of body mass, and grow up to 200 kg. In this study, how they grow to prevail over such big scale effects in the course of growth is investigated..
  • Ecophysiological significance of cannibalism during early life in fish and marine invertebrates
    keyword : Cannibalism, larva & juvenile, metamorphosis, saltation, early mortality
    2000.01~2017.03Ecophysiological significance of cannibalism of teleosts during early life stage Keywords: cannibalism, larvae, juvenile, survival, metamorphosis, saltation, mortality. Teleost fishes usually take the small eggs - high fecundity strategy for reproduction, and few individuals can survive due to the high mortality at the early life stage. This early reduction can be caused mainly by the predation. In this study, mechanisms of cannibalism are elucidated through the ecophysiological and ecomorphological approach using a puffer, a mackerel, etc..
  • Conservation and enhancement of fluvial, estuarine and littoral fields
    keyword : Biodiversity, estuary, diadromous migration, saltwater wedge, small inlet
    2000.01~2017.03Conservation and enhancement of fluvial, estuarine and littoral fields Keywords: diversity, estuary, diadromous migration, saltwater wedge, small inlet. Kitagawa River flowing through the rural area (Miyazaki) and Murasakigawa River flowing through the urban area (Kitakyushu City) are the main fields of this study, focussing on the conservation and enhancement of the ecodiversity of fish community. The results from Kitagawa R. are applied to the practical study in Murasakigawa R. It is the main theme of this study to clarify the nature of WANDO, a small inlet with still water at ordinary water level connected to the main stream. WANDO is considered to be an important component of the river system to conserve the ecodiversity..
