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.

Abstract

An intensive artificial propagation method for Myxocyprinus asiaticus comprises the steps of parent fish selection, induced spawning and hatching. Wherein the induced spawning comprises preparing oxytocic in different doses, administering the oxytocic timely, and designing an oviposition-nest and an oviposition pool, and the hatching comprises designing a hatching pool and determining the special hatching condition. The method of the present invention allows the fry of Myxocyprinus asiaticus to be bred in a large number, the original germplasm to be ensured, the incidence of disease to be reduced, and the survival rate of Myxocyprinus asiaticus to be improved.

Description

technical field [0001] The invention relates to a method for cultivating freshwater fish, and further refers to a method for large-scale artificial propagation of mullet. Background technique [0002] The mullet belongs to the order Cyprinidae, the submouth fish family, and the genus mullet. Commonly known as fire bream, yellow row, wood leaf plate, red fish, blood row, powder row, etc., mainly distributed in the Yangtze River, Jinsha River and other places. The bait swims back into Dongting Lake for fattening, and lives in lakes and rivers. Juveniles and adults have different shapes, habitats and biological learning. Juveniles like to gather and inhabit among gravels with slow water flow, and they mostly move in the upper layer of water bodies. Adults like to live in open water areas of rivers. They are omnivorous and mainly eat invertebrates. And insect larvae, also feed on organic matter at the bottom of the water, suck attached diatoms and plant debris. Due to changes...
