(2) artificial propagation: disinfecting the spawning pond by potassium permanganate when the water temperature reaches 20 ℃ in the last ten days of 4 months to the last ten days of 5 months, and then carrying out stocking on the selected female light yellow fancy carp and male red koi according to the tail ratio of 1:2, wherein the stocking density in the spawning pond is 4-5 tails/m3Female blue-coated fancy carp and male Zhao and tricolor fancy carp are carried out according to the ratio of 1:2, and the stocking density in the spawning pond is 4-5 tails/m3Respectively injecting artificial oxytocin, wherein the dosage of the artificial oxytocin is 3ug LHRH-A2 and 1mg DOM used by every kilogram of female light yellow fancy carp and female blue fancy carp, and the injection dosage of the artificial oxytocin of male red koi, male showa koi and tricolor fancy carp is reduced by half; injecting oxytocin into the parent fish, stimulating the parent fish with micro flowing water, when the parent fish generates oestrus after the water temperature is 20 ℃ and 8-10h, respectively taking female light yellow fancy carp and male red white fancy carp, female blue fancy carp and male showa tricolor fancy carp, simultaneously pressing the abdomen, respectively putting two pairs of extruded sperms and ova of the parent fish into a sterilized small basin, carrying out water-leaving dry insemination, slightly and uniformly stirring by using a feather rod, marking the variety and the operation time of the fancy carp on the small basin after artificial insemination, standing for 0.5h, and converting the ovum grains from transparent to beige fertilized ova;
(3) artificial incubation: gently and quickly and uniformly scattering fertilized eggs in the small basin into an incubation net cage in an incubation pool by using a feather stick, incubating the fertilized eggs in still water, incubating the incubated fries for 7 days when the water temperature is 16-18 ℃, and splashing potassium permanganate once in the middle; after 3 days of fry incubation, uniformly sprinkling egg yolk serum to the whole pond for 1 time every day, when the swimming capacity of the fry is strong, removing the hatching net cage, and transferring the fry into the hatching pond for early-stage cultivation;
(4) fry rearing: and after the larvae break the membranes for 3 days, feeding the larvae, feeding some fresh and alive small rotifers and cladocerans, and after all the larvae are fed for 20 days and the body length of the larvae reaches 3cm, well developing the digestive system of the bred larvae and feeding shrimp fry compound feed or abalone compound feed.
And the female light yellow fancy carp and the male red white fancy carp are mated to breed the blue fancy carp.
The female blue fancy carp and the male Zhao Zhang tricolor fancy carp are mated to breed the tricolor fancy carp.
The spawning pond adopts cement pond materials, and the area of the spawning pond is 8m2The water depth was 20 cm.
The spawning pond is disinfected by potassium permanganate, and the concentration of the potassium permanganate is 10 mg/L.
The invention has the beneficial effects that: the invention cultivates blue-skin fancy carp by using female light yellow fancy carp and male red white fancy carp, and cultivates three-color fancy carp by using female blue-skin fancy carp and male showa and three-color fancy carp, and the cultivated three-color fancy carp has excellent quality, full muscle, bright color, symmetrical and graceful body shape and obvious variety characteristics.
