| Research Abstract |
Our study indicated the importance of benthic diatoms as the most available food for scallops and oysters, suspension feeder bivalves. There are many kinds of species of benthic diatoms living on the shell surface, and they have wide variations in size. Benthic diatoms grown on the shell surface and the cages are taken by scallops and oysters with cilium movement. The stable growth for benthic diatoms may depend on the constant supply of nutrients by sessile animals on the cages and shell surface. We discovered the importance of micro-material circulation in the waters for the aquaculture systems of the bivalves.
