The invention belongs to the technical field of fish reproduction, and discloses a method for breeding Channaidae fish by using artificial insemination and hatching tanks. Selected broodstock are temporarily raised in a cement pond with a water temperature of 25-26°C, and induced labor is carried out; In a cement tank with a water temperature of 28-29°C, after the effect time is reached, check the egg squeeze every 2 hours, and perform a total of 3 times; after the egg squeeze, the broodstock is kept temporarily, and penicillin is used to prevent inflammation, and the female broodstock survives more than 75% ; The male fish takes the testis, and grinds it with a metal mesh in the sperm preservation solution; before fertilization, the sperm in the sperm preservation solution is activated with water, and then poured into the eggs for fertilization. The eggs are fertilized and left to stand for more than 2 hours, then hatched in the hatching bucket, and the hatching bucket is inflated; the fertilized eggs are hatched in the bucket for 2 days to produce membranes, and after another 1-2 days, the yolk sac is completely absorbed, and the seedlings are cultivated. The invention significantly improves the utilization rate of male broodstock and the postpartum survival rate of female broodstock, reduces site occupation and improves the success rate of seed hatching.

The biopharmaceutical periplaneta americana cultivation reproduction incubator has the advantages that the temperatures and the humidity required by incubation environments can be provided to ootheca incubation, the incubation environments in the incubation boxes can be continuously monitored, regulated and controlled by the aid of temperature sensors, humidity sensors and a control center, and accordingly periplaneta americana in oothecae can be successfully incubated; the periplaneta americana incubation efficiency can be effectively improved by the biopharmaceutical periplaneta americana cultivation reproduction incubator, the egg incubation success rate and the larva incubation survival rate further can be increased, and the biopharmaceutical periplaneta americana cultivation reproduction incubator is simple in structure and convenient to use.

The invention relates to a propagation method of flame turtles. The method includes the steps of (1) selecting the flame turtles which are red as fire in shell color, oval in shape and free of body defects to serve as parent turtles; (2) feeding the parent turtles once every 1-2 days, and adding a certain quantity of Chinese medicine soak solutions and microalgae powder into the feed 5-10 days before egg laying; (3) laying egg laying substrates on an egg laying place, picking turtle eggs from the egg laying place 7 days after egg laying, laying incubation substrates with thickness of 5-8 cm on the bottom of an incubation box, placing the fertilized turtle eggs on the incubation substrates, covering the turtle eggs with incubation substrates with thickness of 4-7 cm, putting allicin on the surfaces of the incubation substrates, and then conducting incubation; (4) transferring the turtle eggs to be hatched into another incubation box, after the young turtles pip, putting the young turtles after sterilization into a disk without water, and transferring the young turtles into a nursery pond for culture after umbilical cords shrink. The propagation method of the flame turtles has the advantages of being easy to operate, high in fertilization rate and incubation rate of turtle eggs and the like.

The invention discloses a control method of sexuality of Gekko japonicus juveniles. The control method comprises the following steps of 1) going through the appearances and the colors of collected Gekko japonicus ova, selecting the ova, which are provided with a complete fragile egg shell and is ivory and faint pink, and removing unfertilized ova and the ova with the formed embryos; 2) placing the Gekko japonicus ova, which conform to the requirements, into a plastic incubation box provided with a cover, laying damp vermiculites with the thickness of 1-1.5 cm at the bottom of the box, and burying the half of the ova into the damp vermiculites; 3) setting the temperature of the plastic incubation box within the scope of 28-32 DEG C, and inoculating in a constant temperature room for 40-56 days. According to the control method, the Gekko japonicus juveniles with the required sexuality are obtained through controlling the inoculation temperature and dropping a letrozole anhydrous alcohol solution.

The invention provides an artificial propagation method of common snapping turtles. The artificial propagation method comprises the following steps of (1) raising the common snapping turtles in an open-air pond, wherein weeds in the open-air pond cannot be weeded and can be kept in a natural state; and setting common snapping turtle egg laying positions in the open-air pond by using soft loess; (2) in an egg laying season, feeding the common snapping turtles with live fish or live shrimps at 7-8 a.m. every day in time, detecting egg laying situations by a raiser at regular times, and preventing the raiser from getting close to the open-air pond; (3) after one week of egg laying, picking fertilized eggs from the egg laying positions, and putting the fertilized eggs on indoor yellow sand; (4) after the fertilized eggs are hatched on the yellow sand for one month, picking the hatched eggs from the yellow sand, putting the hatched eggs in boxes paved with vermiculites, and hatching in a greenhouse; (5) picking turtle larvae after the turtle larvae are hatched out of shells and umbilical cords are put away, putting the turtle larvae in plates with water, and enabling the back parts of the turtle larvae not be covered by the water. According to the new propagation method provided by the invention, the egg laying amount of the common snapping turtles and the success rate of hatching the eggs are increased, and the economic benefit is increased.

The invention discloses a Procambarus clarkii implantation device and a hatching method thereof. There are several vertical ridges, and gaps are formed between adjacent vertical ridges. There are drainage holes at the bottom of each cell cavity; the water mixed with shrimp eggs is injected into the cavity and continuously filled with water. After the shrimp eggs on the bed are implanted, place the implantation plate on the blocking plate, and each drainage hole on the blocking plate is provided with a corresponding ejector structure, and the drainage holes on the implantation plate are covered by the ejector structure. For blocking, a column grid frame is erected on the bed plate, and the side wall of each cell on the column grid frame surrounds the cells, and material exchange cannot be performed between adjacent cells. The implantation device mentioned in the present invention can provide a good environment for the hatching of shrimp eggs and improve the overall hatching efficiency.

The invention discloses a hatching method of Mauremys mutica. In propagation season, ventilate plastic box is taken as hatching box. Vermiculite layer of 3-6cm thickness is laid on the bottom of the hatching box as hatching medium. Fertilized eggs are put on the hatching medium with the space of 0.3-0.8cm, and then another layer of vermiculite of 2-3cm thickness is covered on the fertilized eggs.The humidity of the vermiculite layers in the whole hatching period is maintained 15 percent-20 percent, and the temperature in the whole hatching period is controlled 25-33 centigrade. Young tortoises are hatched 55-63 days. The invention adopts the vermiculite as the hatching medium, makes use of the preferable warmth retention property, moisture retention property and permeability of the vermiculite, improves the hatching success rate of the Mauremys mutica, shortens the hatching period and enhances the quality of newborn young tortoises.
