Abstract

Impacts of the construction of large-scale port and harbor at open sandy beach on inhabitation of the Japanese surf clam (Splsula sachalinensls) have been studied. It has been found that the populations of the Japanese surf clam has been increasing with the extension of the breakwater since the start of the construction of Ishikari Bay New Port in 1972. A series of numerical simulation was carried out to estimate the changes over time in the currents distribution around Ishikari Bay New Port associated with the construction of the breakwater for each construction phase. The change in dominant areas of the Japanese surf clam in the harbor over the years is explained by patterns of nearshore currents around the port. The construction of Ishikari Bay New Port resulted in the formation of a new fishing ground of the Japanese surf clam and an increase in the populations of the clams.
