Problems solved by technology

At the same time, the construction of the dam will also reduce the reddrill's habitat and spawning grounds, making it more difficult for them to find a mate, which will adversely affect the recovery and growth of the population

Embodiment 1

[0036] 1. Collection and temporary rearing of broodstock: Collect wild reddrills with a weight of more than 1.2kg by net fishing, and select healthy reddrills with full vitality and intact body surface as broodstocks. Use a live fish cart to transport fish. The fish box of the live fish cart is length*width*height=100cm*600cm*40cm. Continuous inflation is adopted, and ice is added to the water to lower the water temperature. After immersing in 3% salt water for 15 minutes, transfer it to a holding pond for holding temporarily. The holding tank is a glass fiber reinforced plastic fish fry breeding tank with a diameter of 2.0m and a water depth of 0.3m. The water temperature is kept at 24.5°C, and it is continuously inflated to maintain a flushing state;

[0037] 2. Selection of broodstock for induced spawning: select healthy and active broodstock for induced spawning. The ratio of male to female broodstock is 2:3, and the weights are 3.0, 3.1, 1.7, 1.5 and 1.2kg respectively; ...

[0043] 1. Collection and temporary rearing of broodstock: Collect wild reddrills with a weight of more than 1.2kg by net fishing, and select healthy reddrills with full vitality and intact body surface as broodstocks. Use a live fish cart to transport fish. The fish box of the live fish cart is length*width*height = 100cm*600cm*40cm. Continuous inflation is adopted, and ice is added to the water to lower the water temperature. The water temperature is maintained at about 25°C. After immersing in 3% salt water for 20 minutes, transfer it to a holding pool for holding temporarily. The holding pool is a 200L water tank (length*width*height=80cm*100cm*25cm), the water temperature is kept at around 25.4°C, and it is continuously inflated to keep flushing;

[0044] 2. Selection of broodstock for induced spawning: select healthy and active broodstock for induced spawning. The ratio of male to female broodstock is 1:2, and the weights are 6.0, 2.2 and 1.3kg respectively;

Abstract

The invention relates to an artificial propagation method of bagarius rutilus, and belongs to the technical field of artificial propagation of fish. The artificial propagation method comprises the following steps that (1), parent fish is collected and temporarily reared; (2), spawning induction parent fish is selected from the parent fish temporarily reared in the step (1); (3), artificial spawning induction is carried out on the parent fish; (4), artificial insemination is carried out; and (5) artificial incubation is carried out. During artificial spawning induction, according to the testis development condition of the male fish, a fish spawning induction agent is injected once or twice, the female fish is injected once, the spawning induction method is determined according to the growth condition of the fish, the female fish and the male fish develop synchronously through a better gonad maturation induction method, the artificial insemination efficiency is improved, the hatching rate is finally increased, and a technical support is laid for population maintenance and growth of the bagarius rutilus.

Description

technical field [0001] The invention belongs to the technical field of artificial reproduction of fish, and in particular relates to an artificial reproduction method of red chinchilla. Background technique [0002] The red chinchilla (Bagarius rutilus) belongs to Osteichthyes, Siluriformes, Sisoridae, broad head and body; wide mouth cleft, sub-inferior mouth; highly keratinized skin; small, oval eyes shaped, located on the lateral dorsal side; maxillary barbels are flattened, with a flap on the proximal side; adipose fin base is short and dorsally angular; body has few spots; large red mandrill has orange fins. The local names of the red grouse are "mian melon fish", "yellow croaker", "stick fish", etc. They are mainly distributed in the Yuanjiang River (also known as the Red River) in my country, the Red River and Ma River in Vietnam, and northern Laos, and feed on animal bait. . [0003] The research work on red mandrill has already carried out classification and naming ...
