Document Type and Number:
Japanese Patent JP7126957
Kind Code:
B2
Abstract:
The present invention provides an aquaculture system in which a biofloc technology is introduced so as make it possible to easily control water quality (C/N ratio) of culture water. Provided is a biofloc technology-based aquaculture system in which a culture water tank is provided with a nitrifying bacterium-immobilized material in which nitrifying bacteria are supported on a carrier.
