A diversion shuttle 14 is arranged in the incubator 3 opposite to the water inlet 12 of the front cover, a cross diversion shuttle fixing rod 15 is arranged in the middle of the diversion shuttle 14, and the tail end of the diversion shuttle fixing rod 15 is fixed on the inner wall of the front cover 13; 3 gill balls 17 are arranged in the middle of the incubator 3 at equal intervals, a gill ball guide pipe 18 is arranged below each gill ball 17, one end of each gill ball guide pipe 18 penetrates into the center of the gill ball 17 and is fixed on a gill ball shell 27 of the gill ball 17, the other end of each gill ball guide pipe 18 penetrates through a gill plate hole 21 in a gill plate 20, a gill plate hole sealing ring 19 is arranged on each gill plate hole 21, and the gill plate 20 is fixed in a rear cover 22 and begins to close.
Referring to fig. 5, the gill ball 17 includes a gill rod 26 and a gill ball shell 27, the gill ball shell 27 is a hollow spherical structure, and the gill rod 26 is uniformly distributed outside the gill ball shell 27.
Referring to fig. 6, the gill bar 26 includes gill tube 28, gill lamella 29 and gill hole 30, the top of gill tube 28 is the hemisphere, gill lamella 29 is equipped with equally spaced around the upper middle part of gill tube 28 outside, the inside hollow structure of gill lamella 29 and with the inside intercommunication of gill tube 28, the equal spaced apart gill hole 30 in the clearance that produces outside gill tube 28 between gill lamella 29 both sides and gill lamella, the lower extreme of gill tube 28 vertically penetrates gill ball shell 27 and is fixed in gill ball shell 27.
The device drives water flow to flow by using the peristaltic pump, the flow rate is controlled to be 0.5ml/min, when the device is installed, the water outlet 23 of the rear cover is connected with the water inlet pipe of the peristaltic pump, and the rear end 11 of the water pipe is connected with the water outlet pipe of the peristaltic pump.
When the peristaltic pump works, water flow enters from the front end 8 of the water inlet pipe of the simulated freshwater mussel and sequentially flows through the water inlet pipe 6, the rear end 10 of the water inlet pipe, the connecting pipe 2, the water inlet 12 of the front cover, the interior of the front cover 13, the gill holes 30 in the gill petals 29 and the gill pipes 28, the interiors of gill balls 17, the gill ball pipes 18, the middle and rear portion of the rear cover 22, the water outlet 23 of the rear cover, the water inlet pipe of the peristaltic pump, the water outlet pipe of the peristaltic pump, the rear end 11 of the water outlet pipe.
When Rhodeus propagation is carried out, the device is placed on the water bottom, peristaltic pump connection is completed, then the fixing fork 9 at the lower end of the simulated freshwater mussel 1 is inserted into the water bottom sandstone, or the fixing fork 9 is bent 90 degrees towards the two sides of the simulated freshwater mussel 1, the simulated freshwater mussel 1 is enabled to stand in the water, the front end 7 of the water outlet pipe and the front end 8 of the water inlet pipe are always exposed out of the water bottom sandstone, and the power supply of the peristaltic pump is turned on, so that water flows in the device. After the Rhodeus finds the simulated freshwater mussel 1, the female fish can extend out of the oviduct and is inserted into the front end 8 of the water inlet pipe of the simulated freshwater mussel 1, eggs are laid in the water inlet pipe 6, and then the male fish also ejaculates at the position close to the front end 8 of the water inlet pipe of the simulated freshwater mussel 1, so that sperms enter the water inlet pipe 6 from the front end 8 of the water inlet pipe along with water flow, the eggs and the sperms sequentially reach the inside of the front cover 13 along with the flow of the water, and due to the shunting and blocking effect of the flow guiding shuttle 14 on the water flow, the water flow drives the eggs and the sperms to be fully mixed in the front cover 13. Fertilized eggs reach the vicinity of the cheek ball 17 along with water flow, and because the water flow in the cheek holes 30 on the cheek bar 26 generates suction and the adhesive force generated by the protrusion of the adhering end at the upper front end of the fertilized eggs, the fertilized eggs are finally attached between the cheek flaps 29, and because the work of the peristaltic pump enables the water flow to continuously flow in the device, sufficient oxygen required by the development of the fertilized eggs can be supplied, so that the fertilized eggs can normally grow and develop in the device until the fertilized eggs are hatched into young fishes, and the young fishes swim out from the front end 8 of the water inlet pipe. The device can be used for completely replacing freshwater mussels, so that the fertilization rate and the hatching rate are improved by 20-30%. After use, the device is disassembled and can be reused after being washed, disinfected and sterilized.
Example 2: if breed on a large scale, the inside three cheek ball 17 that is equipped with of the device can adsorb the embryonated egg in a large number, take apart the incubator and make front shroud 13 and rear shroud 22 separation, can observe the absorption condition of embryonated egg on gill stick 26 with the naked eye, if distribute the embryonated egg on the gill stick 26, can shift the device to the hatching pond and hatch, perhaps change out the cheek ball 17 that distributes the embryonated egg, continue to put the device in the original place and carry out the embryonated egg and gather, shift the cheek ball 17 that changes out to the hatching pond of light-resistant and hatch. During incubation, the water in the incubation pool needs to be kept to continuously circulate to provide sufficient oxygen, and the incubation temperature is 20-30 ℃. The device can be used for indoorly, also can be used to outdoors for when outdoor, equally can gather the deus Rhodes zygote in a large number in the field through changing cheek ball 17, then concentrate the hatching.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
