Method of symbiosis production of green algae and fish using dead algae

摘要

The screen-blocked cage for high density culture or green algae (I) including chlorella or spirozyra of chlorophyceae is located at 30cm below the surface of the pond. At the bottom of the pond, the fish can be grown to supply carbon dioxide and organic wastes for (I)'s growth. Eventhough the feed is supplied manually, oxygen for fish respiration is diffused from (I)'s photosynthesis at the top. This symbiotic system is designed for high density culture of (I) and fish, based on (I)'s oxygen supply and fish's carbon dioxide and nitrogen sources. The culture mass of (I) is harvested by lifting the cage every sun-set and dried by air, and fish are harvested every month.
