Study on living of mahogany clams under the deposited sand

Abstract

The mechanism of how mahogany clams could live at the depth of over 50 cm in tidal flat was examined by field and laboratory experiments. The mahogany clams bred in the different depth of tidal flat (10 to 50 cm). And the migration of mahogany clams in the tidal flat was investigated. It was understood that mahogany clams could live two months without feeding and breathing through the tidal flat surface. Moreover, survival rate of mahogany clam bred near the lowest groundwater level was higher than that near the tidal flat surface (0 to 10 cm).
