s2, artificial insemination: when female fish are in sexual maturity, selecting healthy male fish with sexual maturity, manually extruding semen into a sterile disc, fishing out the female fish, manually extruding eggs, and stirring with sterilized feather for 1min to mix the semen and the eggs;
s3, hatching fertilized eggs: putting the fertilized egg cells into an incubation cylinder, controlling the temperature of water in the incubation cylinder to be 20-25 ℃, and incubating the fertilized eggs after 28 hours;
s4, fry breeding: transferring the incubated fry to a culture tank after 1-2 days, keeping the temperature of the culture tank at 20-25 ℃ and the pH of a water body at 7.5-8.5, keeping illumination for 8 h/day by adopting a special float grass lamp or a fish lamp, and feeding the fry with an opening material; the running water filtering system is used for cleaning the water body, and the water body updating speed in the culture tank is ensured to be 1/4-2/3 tanks every day.
Preferably, the starter is artemia within 3h of incubation, the feeding amount is 5-10% of the weight of the fry, and the feeding is carried out for 4 times every day.
Preferably, the running water filtering system comprises a liquid flow pipe and a water pump for pumping the water body of the culture tank, wherein the water body is sucked from the water inlet end of the liquid flow pipe and is filtered by the filtering component outside the culture tank and then returns to the culture tank from the water outlet end of the liquid flow pipe.
Preferably, the water outlet end of the liquid flow pipe is arranged in an overflow box attached to the edge of the inner wall of one side of the culture tank, and water flows into the overflow box from the water outlet end of the liquid flow pipe and then overflows into the culture tank to reduce water disturbance.
Preferably, the water suction port of the liquid flow pipe is provided with a layer of filter screen, and the aperture of the filter screen is smaller than the body width of the fry.
Preferably, an oxygen increasing device is further arranged in the overflow box.
Preferably, in S4, the PH of the water body is adjusted by using baking soda.
Preferably, the fairy shrimp is obtained by hatching fairy shrimp eggs, removing egg shells and filtering impurities through a 20-30 mesh net.
The invention has the beneficial effects that:
the indoor culture of the Taishi goldfish comprises the steps of fishing out female fish and male fish and feeding the female fish and the male fish in separate cylinders when the male fish knocks into the tail, so that the female fish and the male fish with consistent sexual maturity time can be obtained, fertilization of one-time spawning of the female fish can be completed, and waste is avoided.
The hatching tank and the breeding tank adopt strict temperature control technology to ensure that the water temperature is always between 20 and 15 ℃, and the temperature interval can ensure high hatching rate of fertilized eggs and high survival rate of fish fries; the culture tank ensures illumination for 8 hours every day, a professional fish lamp or a float grass lamp is used for simulating an outdoor natural environment, healthy development of the Taishi goldfish is facilitated, the generation of a fish-float imbalance is reduced, the color development of the Taishi goldfish is facilitated, meanwhile, the long-time illumination can promote the proper amount of green algae in the water body to be generated and not to be exposed to the algae, the proper amount of green algae in the water body can provide certain nutrient substances for the Taishi goldfish, and nitrogen and phosphorus components are consumed. If the illumination time is too long, the algae exposure occurs, on one hand, the water quality, especially the oxygen content of the water body, can be reduced, the growth of the Taishi goldfish is influenced, on the other hand, the culture tank is not easy to clean, the green algae attached to the wall of the tank needs to be manually eradicated, the water is completely changed, and the growth of the Taishi goldfish is easily damaged in the process.
The running water filtering system can avoid manual water changing, in the traditional culture mode, the Taishi goldfish needs to be deeply cultured in still water, but frequent water changing is needed to avoid the Taishi goldfish from infecting bacteria due to water quality aging, and the water changing easily damages the developing Taishi goldfish, so that key ornamental parts such as the head, the tail and the like are damaged, or swimming bladder imbalance disease occurs, and the ornamental value as a side-looking fish is lost.
According to the indoor breeding method of the Taishi goldfish, the fertilization rate of the ovum is more than 95%, the hatching rate of the fertilized ovum is more than 90%, and meanwhile, the limitation that the Taishi goldfish is bred outdoors for only 1-2 seasons of a year is broken, so that the Taishi goldfish can be bred all the year round.
