Research Projects
  1. Fluctuating mechanisms of coastal resources

    The sea is not an inexhaustible source of food for mankind. Coastal sea bring up various organisms and provide us familiar foods. Beside that, so many fishermen live on the gift from coastal sea. I am studying the coastal fisheries biology and its relationship with environmental condition, and trying to reveal the fluctuation mechanism of coastal resources and to theorize the fisheries management for them.

  2. Age determination and analysis of environmental history using fish otolith

    Annual ring, daily increment and change structure induced by life history events are formed in the fish otolith. Furthermore, trace elements reflecting the environment are accumulated to the otolith calcium carbonate. In order to reveal the fish ecology and improve the accuracy of resource analyses, I try to establish age determining criteria, and to estimate the environmental history of individuals, based on changes in the minute structure and in the trace elements of fish otolith.

Research Seeds
  • “ Fish Ecology Rvealed by Otoliths, Biology of an Eloquent Small Bone” has been published 978-4769916604

    Otoliths that have become commonly used in ecological research and stock assessment for fisheries resources. Although 555 species of otolith atlas have already been printed in Japan (Iizuka and Katayama, 2008), there was no publication that comprehensively explained the basics and applications of otoliths. This book is widely available to high school students and fisheries researchers.。ISBN-13: 978-4769916604

  • Impacts of environmental changes on ring formation, transparency external morphology,  and minute structure of fish otolith

    XXXX Analysis of marbled flounder in Tokyo Bay and rearing experiments revealed the relationships of water temperature and the transparent zone and opaque zone, hypoxic conditions and the otolith Mn concentration, chemical substances and the otolith crystal structure, and pH and the otolith external morphology. Observation of otoliths suggests that the environmental history of individual fish can be estimated.
