BIOFLOC SYSTEM WITH AIR INJECTOR ON INTERMEDIATE LAYER FOR CULTURING BENTHIC FISH

摘要

The present invention provides an intermediate layer air injector type biofloc system for cultivating benthic fish. The biofloc system includes: a biofloc cultivation water tank for storing cultivated organisms and breeding water while having a floor and outer walls in a predetermined area; an air injector which is formed on a surface at one third or half of the height of the biofloc cultivation water tank while being tilted from the floor of the biofloc cultivation water tank to supply air into the breeding water; and a pump which is formed on the outside of the biofloc cultivation water tank and supplies air to the air injector. The biofloc system releases the stressful environment including the benthic fish created by strong water flows on the lower part of the biofloc cultivation water tank for stirring solid sludge and circulating the breeding water in a biofloc cultivation operation to provide a cultivation environment similar to a natural habitat as well as easily circulating the breeding water and stirring solid sludge, thereby executing an efficient biofloc cultivation operation for the benthic fish such as loach and eel.;COPYRIGHT KIPO 2017
