Embodiment 1
[0013] 1. Source of broodstock: Chenghai white fish (common name: white striped fish) from Chenghai Lake.
[0014] 2. Training and breeding of broodstock: Put the broodstock into Chenghai Sea and Shanquanshan in a mass ratio of 1:0.3 and then raise them in ponds. The pH value of the water is 8, and the water temperature is 14°C to 28°C. Block stone caves create natural waves.
[0015] 3. Breeding: build a 35-degree slope with stones on one side of the pond, spread sand on the slope, stimulate broodstock with running water, and make broodstock lay eggs on the stones or sand in the running water; Broodstock that lay eggs on stones or sand are placed in ponds at a ratio of 2:1 male to female after being induced by drugs. The eggs can be laid on stones; the remaining broodstock that have not laid eggs can be reproduced by artificial insemination.
[0016] 4. Hatching: fish eggs are placed in the hatching tank, the hatching water temperature is 18 ℃ ~ 26 ℃, the water depth is 30 ...
Embodiment 2
[0020] 1. Source of broodstock: Erythrocultermongolicus elongates He et Liu from Chenghai Lake.
[0021] 2. Training and breeding of broodstock: Put the broodstock into Chenghai Sea and Shanquanshan in a mass ratio of 1:0.25 and then raise them in ponds. The pH value of the water is 8, and the water temperature is 14°C to 28°C.
[0022] 3. Breeding: build a 45-degree slope with stones on one side of the pond, spread sand on the slope, stimulate broodstock with running water, and make broodstock lay eggs on the stones or sand in the running water; The broodstock that lay eggs on stones or sand are placed in the pond at a ratio of 2:1 male to female after being induced by drugs. And brown skin, fish eggs can be laid on branches and brown skin; the remaining broodstock that have not laid eggs are reproduced by artificial insemination.
[0023] 4. Hatching: fish eggs are placed in the hatching tank, the hatching water temperature is 18 ℃ ~ 26 ℃, the water depth is 30 ~ 80 cm, the...
Embodiment 3
[0027] 1. Source of broodstock: Distoechodontumirostr is Peters, a round-nose pomfret (common name: red-finned fish) from Chenghai Lake.
[0028] 2. Training and breeding of broodstock: Put the broodstock into Chenghai Sea and Shanquan Mountain in a mass ratio of 1:0.35 and then raise them in ponds. The pH value of the water is 7.5-9, and the water temperature is 14°C-28°C.
[0029] 3. Breeding: build a 40-degree slope with stones on one side of the pond, spread sand on the slope, stimulate broodstock with running water, and make broodstock lay eggs on the stones or sand in the running water; Broodstock that lay eggs on stones or sand are placed in ponds at a ratio of 2:1 male to female after being induced by drugs. The eggs can be laid on stones; the remaining broodstock that have not laid eggs can be reproduced by artificial insemination.
[0030] 4. Hatching: fish eggs are placed in the hatching tank, the hatching water temperature is 18 ℃ ~ 26 ℃, the water depth is 30 ~ 8...
