Contents of Research

(1) Research on reproduction, ecology and parasitism of benthic animals.
We conduct research on the attributes of life history, reproduction, feeding and the relations between hosts and parasites of crustaceans and shellfishes in coastal areas.Recently we are studying the reproductive behavior of fiddler crabs, the life history and resource management of the hamaguri clam, and the population dynamics of the amphioxus.

(2) Research, analysis and management of the resource decrease of fishery species
For a sustainable fishery, we develop resource management and cultivation technologies, mainly in bivalves, e.g. hamaguri clams and tairagi fan shells.

(3) Conservation, regeneration and reproduction of the habitat of benthic animals.
For the conservation of tidal flats and saline wetlands, we research the life history and the population dynamics of benthic animals, one of the most important species in these habitats.

In addition to studying the regeneration and reproduction in habitats, we also study the artificial breeding of benthic animals.
