| Research Abstract |
In this study, habitat quality for stream-resident red-spotted masu salmon was evaluated using a bioenergetics model that estimates energetic profitability for fish. We demonstrated that effects of coniferplantation on habitat quality for red-spotted masu salmon can be quantitatively evaluated using the model. In addition, our analysis revealed that streamside vegetation adjacent to target reaches (rather than vegetation condition at catchment scale) should befocused when effects of forest vegetation on prey abundance for the salmon are assessed.
