The invention provides an artificial breeding method of spinibarbus capito, which is suitable for Dongting Lake in Hunan Province and four water basins of Hunan, Zi, active yuan and halite, and comprises the steps of parent fish rearing, artificial spawning induction and artificial incubation, and spawning can be carried out for 1-2 times in one year. In the spinibarbus capito parent fish rearing process, puffed floating fish feed is used as a main material and properly matched with green feed, animal bait is added for feeding 2 months before winter, accumulation of fish body fat can be guaranteed so that the fish can smoothly pass the winter, vitamin E, vitamin C and flowing water stimulation are supplemented in the feed before antenatal, and ovary development and ovum maturation can be effectively promoted; the artificial spawning induction adopts a two-needle injection method, the spawning induction efficiency is high, and the fertilization rate is high; through comparison of different hatching devices, the hatching effect of the hatching frame is best, the hatching rate reaches 80% or above, the hatching barrel is inferior, and the small net cage is worst. By means of the artificial propagation method, large-scale production of spinibarbus capito can be achieved, and the method is of great significance in improving the economic benefits of farmers and popularizing the spinibarbus capito artificial propagation technology.

The invention discloses a mastacembelus armatus fertilized egg debonding device and debonding method.The mastacembelus armatus fertilized egg debonding device comprises an incubator, a first guide rail and a second guide rail are arranged above the incubator, and one end of the second guide rail is connected with the first guide rail through a fixing rod; the first frame body is movably arranged between the first guide rails, the first frame body is rotatably provided with a temporary storage box, and the outer wall of the temporary storage box is connected with a first vertical block; the second frame body is movably arranged between the second guide rails, the second frame body is provided with a second vertical block, a first linkage mechanism is arranged between the second vertical block and the first vertical block, the first linkage mechanism is used for locking or unlocking connection between the second vertical block and the first vertical block, a second linkage mechanism is arranged between the second frame body and the fixing rod, and the second linkage mechanism is used for locking or unlocking connection between the second vertical block and the first vertical block. The second linkage mechanism is used for locking or unlocking connection between the second frame body and the fixing rod. According to the unsticking device for the fertilized eggs of the mastacembelus armatus with the structure, the unsticking and dumping modes of the fertilized eggs can be standardized, and the fertilized eggs are uniformly scattered into the incubator.

The utility model discloses a kind of young turtle hatching temperature control devices, belong to hatching field, including box and the temperature control structure assembled on the top of box, and the replacement structure assembled in the inside of box, the temperature control structure includes the blocking frame fixedly connected in the top of box and the exhaust fan fixedly installed in the inside of blocking frame, and electric push rod fixedly installed in the top side of blocking frame, the upper cover of exhaust fan is equipped with round block.The utility model is equipped with the setting of temperature control structure, exhaust fan is then through the heat dissipation of collaborative adjustment with baffle and round block.Electric push rod drives the movement of baffle and round block by connecting rod and guide rod, so that sealing washer is separated from exhaust groove, and round block no longer blocks round hole, to realize the circulation of air in and out of box, simultaneously, the closing effect of round block and baffle can effectively seal box, prevent external air from entering through round hole and exhaust groove, to reduce temperature fluctuation in hatching process, improve hatching effect.

The utility model discloses a quail hatching cage with uniform temperature, which belongs to the technical field of quail hatching and comprises a hatching box for quail hatching, a fixing plate is welded on the upper side of the hatching box, and a first motor for providing power for quail hatching with uniform temperature is mounted on the side edge of the fixing plate. The lower side of the connecting block is fixedly connected with a sliding plate in sliding connection with the incubator body, buffer springs welded to the incubator body are welded to the two sides of the sliding plate, and a heating lamp used for quail incubation is installed on the lower side of the sliding plate. The angle of the connecting rod is changed through rotation of the rotating disc, the connecting block and the sliding plate are driven to move circularly, all the quail eggs can be irradiated, all the quail eggs can be irradiated sufficiently, the situation that the irradiation intensity of the quail eggs is not uniform is avoided, and the hatching effect is enhanced.

The application discloses a kind of quick detection system and method of chicken embryo heart rate and response degree to light environment, comprising: box, light source, egg test fixing frame, temperature control device, light source controller, infrared emission and receiving device, computing module;Egg test fixing frame is used to carry the egg to be detected;Temperature control device is used to control the temperature in box and keep constant temperature;Light source is used to provide light source for egg;Light source controller is used to adjust light source to emit light source of different intensity, different wavelength;Infrared emission device is used to emit infrared light to the chicken embryo inside egg;Infrared receiving device is used to receive the infrared light reflected by chicken embryo and convert into electrical signal transmission to computing module;Computing module is used to receive respectively the electrical signal transmitted by infrared receiving device when egg is under different intensity, different wavelength light source and no light source condition and carry out data processing, obtain the heart rate value of chicken embryo in egg.The application can quickly detect and obtain the heart rate of chicken embryo and its response degree to light environment.

This invention belongs to the field of acidifier technology, specifically relating to an acidifier that can improve the health of breeding ducks and the hatchability of hatching eggs, its preparation method, and its application. The acidifier includes acidifier A and acidifier B. Acidifier A is prepared by mixing and adjusting the volume of calcium formate, acetic acid, lactic acid, monk fruit extract, and an immune enhancer; acidifier B is prepared by mixing and adjusting the volume of calcium propionate, citric acid, malic acid, stevia extract, and an antioxidant. This invention enhances the immunity and antioxidant capacity of breeding ducks and improves eggshell quality by intermittently and alternately adding the two acidifiers to their drinking water during the egg-laying period. Furthermore, by spraying a proportionally diluted mixture of the two acidifiers during the later stages of hatching, it improves embryonic calcium absorption and duckling shell-pecking rate, reduces embryonic mortality, and significantly increases the hatchability of hatching eggs. This invention is suitable for large-scale breeding and hatching of breeding ducks.
