| Abstract: | The spatial distribution of the larval abundance of the clam Ruditapes philippinarum has been investigated at 65 stations throughout Tokyo Bay on August 2, 2001. The large number of small D-shaped larvae that
were found shortly after hatching in the waters around the Banzu, Futtu, and Sanmaizu-Haneda areas indicates that spawning
populations in these areas probably contribute greatly to the larval supply in the bay. Small larvae also occurred abundantly
around the Yokohama and Ichihara port areas, suggesting that these port regions play a role in the transport of larvae into
Tokyo Bay.
