Many kinds of marine aquaculture have been conducted in the semi-enclosed bay. In Sido-bay where located north-eastern area of Kagawa Prefecture could produce marine aquaculture productions to supply the population demands. On the other hand, the feeding rate of fish farming is approximately 13,000 tones by year, which highest feed in the summer season. Therefore, the pollution from many floating aquaculture facilities can affect the environment via fecal waste and excess feed settles. After the field research, it was found the tidal current, bottom topography and dissolved oxygen consumtion rate by sediment are very important factors to evaluate the carrying capacity of aquaculture grounds. The authors proposed more quantitative evaluation technique for the capacity using the numerical model taking the effect from the oxygen consumtion by the fish in the aquaculture cage and bottom sediment.
