Example Embodiment
[0020] Embodiment 1: the large-scale artificial propagation method of rouge is:
[0021] (1) Selection of broodstock: select mature broodstock with complete scales and a body weight of not less than 8kg, and the ratio (quantity ratio) of female broodstock to male broodstock is 1:1;
[0022] Mature broodstock: male broodstock gently presses the abdomen, milky white semen flows out, and it disperses after entering the water; female broodstock has a swollen abdomen, and the outline of the ovary can be seen by turning the belly of the fish upwards. more than 2mm;
[0023] (2) Induction of labor:
[0024] a. Oxytocin drugs: chorionic gonadotropin (HCG), luteinizing hormone-releasing hormone analog (LRH-A), dione maleate (DOM), carp, crucian carp pituitary (PG) mixture of four drugs ;
[0025] b. The total dosage of oxytocin per kilogram of female broodstock body weight:
[0026]
[0027] The dosage of oxytocin per kilogram of male broodstock body weight is half of the above ...
Example Embodiment
[0038] Embodiment 2: in the large-scale artificial reproduction method of rouge, the total consumption of the oxytocin drug of every kilogram of female broodstock body weight:
[0039]
[0040] The dosage of oxytocin per kilogram of male broodstock body weight is half of the above dosage;
[0041] The rest of the procedure is the same as in Example 1.
Example Embodiment
[0042] Embodiment 3: in the large-scale artificial reproduction method of rouge, the total consumption of the oxytocin drug of every kilogram of female broodstock body weight:
[0043]
[0044] The dosage of oxytocin per kilogram of male broodstock body weight is half of the above dosage; other processes are the same as in Example 1.
