The invention discloses a method for
artificial reproduction of
brachymystax lenok tsinlingensis. The method for
artificial reproduction of the
brachymystax lenok tsinlingensis comprises the steps that (A) mature and highly active
brachymystax lenok tsinlingensis is selected to serve as a parent; (B) reinforced cultivation of the parent is conducted; (C) artificial spawning is conducted, wherein two dosages of artificial spawning
medicine is injected into the parent for artificial spawning from the end of March to the middle of April; (D)
semen collection is conducted manually, wherein the parent is bred in an artificial spawning pond after the artificial spawning
medicine is injected into the parent, a water inlet
pipe is erected at one end of the artificial spawning pond, and the
abdomen of the brachymystax lenok tsinlingensis parent is pressed regularly so that
semen collection can be achieved from the alive brachymystax lenok tsinlingensis parent; (E)
artificial insemination is conducted, wherein after an ovum is rinsed with normal
saline for fish is collected, seminal fluid of a milter is squeezed on the ovum, then mixing is conducted with a
feather, andartificial
insemination is conducted; (F) artificial incubation is conducted, wherein a fertilized ovum is washed with
purified water and then is poured in an incubation groove for incubation, a porous
dandruff comb is arranged on the bottom of the incubation groove, and when fry which can swim appears, the fry is moved out of an incubation device to be bred in a
fish tank. The method for
artificial reproduction of the brachymystax lenok tsinlingensis is easy to implement, operation is easy and convenient, the fertilization rate and the
hatching rate are high, obtained fish
offspring are healthy, the body sizes of the obtained fish
offspring are even, the rate of survival is high, the
utilization rate of fish bait is high, and the growing speed is high.
