It's common knowledge that the artificial creation of shallows including tidal flats has great water purification function. Therefore, creating tidal flats in Mikawa Bay of Japan, we believe it is important to choose areas that will be the most effective for the recruitment and/or supply of pelagic larvae. Firstly, we selected the short-necked clam (Ruditapes philippinarum) as a target species, and used a receptor mode model to predict trajectories of the pelagic larvae flow towards the Isshiki tidal flat areas. The results show that: (1) The main sources of larvae supplied to this area are the inner parts of the bay: (2) The trace routes vary greatly with temporal wind-induced currents and vertical distribution of the larvae. Secondly, we tried to map the important areas that are sources of larvae by predicting trajectories from 5 areas in Mikawa Bay. Based on the results, the supply patterns to each area were placed into 2 major patterns: self-contained pattern and ingression pattern. From these simulations, we found that the receptor mode model used in this study has been useful in answering some of the difficult questions faced in restoring bay environment, when determining the best location for creating artificial shallows.
