Description
The Sone tidal flat in Kitakyushu city has a dry flat of about 517ha during ebb tides. It is one of the nicest spots for the wild bird observation through the four seasons. It is also famous as the breeding ground of Horseshoe crab (Tachypleus tridentatus). Although large-scale landfills have been recently constructed around the Sone tidal flat, number of Horseshoe crab breeding pairs laying eggs have been increasing. However, they suddenly decreased for the past 2 years. The aim of this study is to understand physical habitat environments of Horseshoe crab larvae and bottom sediment characteristic through field studies.<BR>This study confirmed the bottom sediment characteristics, especially about the bottom sediment hardness. In addition, the relationship between the bottom sediment characteristics and the number of the Horseshoe crab larvae observed was discussed.
