Abstract
In order to contribute to the stabilization of fishery management and the sustainability of fishery resources, fishery development projecs have been carried out. However, about continuons monitoring surveys, it is not easy to assess these project effects on the relation between fishery and environment because of increasing research cost. In this study, we apply HEP(predictive model) to the environmental assessment in red sea bream fishery, the following conclusions are drawn. Of potential prey environment is improved, catches of red sea bream was increased. For about 20% of the total catch of red sea bream, improvement is suggested. Therefore, it is suggested that the model can be used for the environmental assessment of red sea bream.
