GROWTH ENVIRONMENT EVALUATION OF EELGRASS BY HABITAT SUITABLE INDEX MODEL IN THE YATSUSHIRO BAY “NOSAKANOURA”

Abstract

 The Yatsushiro Bay in central Kyusyu, southwest Japan is representative enclosed sea in Japan. Recently, various environmental degradations are reported occur in Yatsushiro Bay, as decrease of fishery resource and eelgrass bed.
 In this study, we tried growth environment evaluation of eelgrass by using HSI model in Yatsushiro Bay “Nosakanoura”. As a result of field data, eelgrass had been grown at the unique environment in Yatsushiro Bay “Nosakanoura”. We showed the restoration technique and the factor which obstructs growing of eelgrass bed.
