PROBLEM TO BE SOLVED: To provide a breeding system which biologically degrades nitrogenous waste such as ammonia, leftover food, feces or the like generated when breeding aquatic animals in a closed circulation type water bath, by using a biotechnology safely and stably in relief at a low cost, in order to realize an advanced water quality environment, and further enables cultivating vegetation on a tray plate to prevent any static electrical charge and make a living environment comfortable. SOLUTION: In the breeding system depending on the biotechnology, the tray plate is set just above the water bath, thereby realizing space saving in assuring an area of a bioreactor and a vegetation bowl and work saving in operation. In a biological capability, reliability is assured by improving the water quality environment which is attained by shortening culture/reaction/degradation periods of microorganisms and the like, by using an aerating nozzle and a carrier filter element with which a structure of a bioreactor vessel is filled up, and an indirect conversion of a heating energy. The advanced water quality environment is kept by combining raw materials for filling up the structure, and using a fiber whose void ratio and water retentivity are high and whose diameter has a large contact area in specific surface. Furthermore, the cultivation of the vegetation on a waterway of the tray plate can improve green amenities (environmental adjustment, perception and psychology). COPYRIGHT: (C)2009,JPO&INPIT
