Abstract: An aerating nozzle assembly has at least one aerating nozzle, and each aerating nozzle has a body, an annular air casing and at least one air tube. The body is tubular and has a channel and a constriction. The constriction is formed around the body and has multiple air holes formed through the constriction and communicating with the channel. The annular air casing is hollow and is mounted around the air holes in the constriction and has an air chamber, an annular surface and at least one air supply hole formed through the annular surface. The at least one air tubes are mounted securely respectively in the air supply holes. Accordingly, the air holes around the constriction allow air to be drawn into the liquid and more completely and homogenously aerate the liquid.

Abstract: The present invention discloses a feeding apparatus connectable to several feeding ducts and includes a first turntable, a fixing plate and a second turntable under a storage bin. The bottom of the storage bin is fixed to the fixing plate, and has several discharge holes, and the first and second turntables can be rotated synchronously, and several outlet holes are built corresponding to the discharge holes. When the first and second turntable are rotated, the positions of the discharge holes and the outlet holes interlaced and superimposed intermittently, so that the feed stored in the storage bin can be dropped intermittently. With a feeding air current, the feed is delivered to the outside in a high speed from each feeding duct, such that each feeding duct can distribute the feed to several feeding points, and the feeding apparatus is particularly suitable for an aquatic farm with high-density breeding tanks.

Abstract: A breeding tank comprising at least two dish-like breeding tubs each having a breeding space and each having a tub bottom and an opening surrounded by a periphery of a top of each of the dish-like breeding tubs, the tub bottoms of all the dish-like breeding tubs are arranged in a mutually vertically stacking mode, and the opening of each lower dish-like breeding tub is larger than that of its-upper dish-like breeding tub, all the dish-like breeding tubs are made of transparent material except the lowermost dish-like breeding tub. The present invention thus can make multiple vertically stacking breeding spaces in a limited space for breeding aquatic animals such as fishes, shrimps and crustacea etc.

Abstract: A sewage treatment system for a breeding system able to guide sewage out of the breeding system to be purified and fed back to breeding ponds for reusing, it can be applied for one breeding pond or applied simultaneously for multiple breeding ponds, and it comprises: a purifying tank, at least a dirt discharging tube to lead sewage in the breeding ponds into a purifying tank; and at least a water take-in tube for feeding purified sewage from the purifying tank back to the breeding ponds. Wherein each dirt discharging tube has a dirt collecting portion; by multiple deposition and purification treatments on the sewage in the breeding ponds with the dirt discharging tubes and the purifying tank, the quality of water in the breeding system can be elevated, and environment pollution during breeding can be effectively reduced.

Abstract: A diagnostic means and method of detecting the presence or the absence of severe acute respiratory syndrome coronavirus antibody in a test sample. The means comprises a solid support, an unlabeled recombinant antigen peptide on a first area of the solid support, a labeled recombinant antigen peptide on a second area of the solid support and an internal control antibody peptide on a third area of the solid phase. The first area is located between the second and the third area.
