The Laboratory of Biology of Aquatic Resources conducts various studies
on fisheries biology for the optimal use of fisheries resources, and ecological studies of reef fishes towards understanding the diversity of adaptative modes in nature.
1) Behavioral ecology and population ecology of fisheries species in Seto
Inland Sea and on coral reefs (Sakai, Y.)
2) Interspecific and animal-environment relationships in coastal waters in relation to the productivity of fishes. (Tomiyama T.)
