Selection of adhering substance during the artificial breeding of Cyclina sinensis

Abstract:

The assay is designed to evaluate the effect of different adhering material on survival and growth rate of Cyclina sinensis larva in economic culture.Adhering assay is under the three states: using yellow sand,sea mud and without any adhering substance.We observed adhering amount and adhering rate of the young shellfish and survival of young shellfish after adhesion.We found that the sea mud is most suitable for adhesion.After that we evaluated the effect of different thickness of sea mud on young shellfish growth.The result shows: Sea mud is most suitable adhering substance in the economic cultivation Cyclina sinensis and the most suitable thickness of the sea mud for Cyclina sinensis larva growth is about 1mm.
