MARICULTURE SYSTEM

摘要

PPROBLEM TO BE SOLVED: To provide a water tank for culturing marine organisms on shore and a culture system using the water tank and bring the culture system to be practical without especially requiring exchange of seawater for a long period of time. PSOLUTION: An apparatus for culturing marine organisms on shore is brought to be practical. The apparatus converts ammonia components generated from excreta of the culture organisms into nitrates through nitrites by using aerobic bacteria, reduces the nitrates to nitrogen gas by using anaerobic bacteria, removes solid components such as residues of feeds and does not require exchange of seawater.
