Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] The invention provides an artificial propagation method for Chinese knotfish. The artificial propagation method has high fertilization rate and hatching rate and good ecological and economic benefits.

[0025] figure 1 A schematic flow chart of the artificial propagation method of Chinese knotfish is shown. Such as figure 1 As shown, the method includes the following steps:

[0026] Broodstock breeding step S1100: selecting 1.5-1.7 kg male fish at 3 winter age and 2.9-3.1 kg 5 winter-age female fish as brood fish, and placing them in a breeding tank for 2 months of cultivation;

[0027] Oxygenation step S1200: in October-November every year, inject oxytocic agent into female fish to induce labor;

[0028] Artificial insemination step S1300: 15-16 hours after induced labor, squeeze out the eggs of the female fish and the sperm of the ...

Abstract

The invention discloses a tor sinensis artificial breeding method including the following steps of parent fish breeding: a 1.5-1.7kg male fish at the winter age of three and a 2.9-3.1kg female fish at the winter age of five are selected to be the parent fish and are cultured in a cultivation pool for two months; spawning induction: an inducing agent is injected to the female fish for spawning induction every October and December; artificial insemination: after the spawning induction for 15-16h, the ovum of the female fish and the sperm of the male fish are respectively extruded to be subjected to artificial insemination to obtain a fertilized ovum; and hatching: the fertilized ovum is arranged in a hatching pool to be hatched for 50-72h. Through the adoption of the artificial breeding method, the hatching rate of the tor sinensis reaches more than 80%, the technical problem that the tor sinensis artificial breeding is unsuccessful at home is solved, and the tor sinensis is artificially bred every October and December. The success of tor sinensis artificial breeding makes a well-known species for fishery cultivation, the fishery development is enhanced, and farmers' income is increased.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an artificial propagation method of Chinese knotfish. Background technique [0002] Chinese knot fish (Tor (Tor) tor sinensis) belongs to Cyprinidae, Cyprinidae, Barb subfamily, Tor (Tor) tor sinensis, commonly known as: carp (Dai nationality). Body side flat, snout pointed, protruding. The mouth is inferior, the lip is thick and fleshy, completely covering the edge of the jaw; the lower lip is divided into 3 lobes, the middle lobe is developed, and it is tongue-shaped, and the rear edge of the middle lobe is almost level with the corner of the mouth in adult fish. 2 pairs of barbels, snout barbels short, behind maxillary barbels extending to posterior edge of eyes. The scales are large, with 23-26 scales on the lateral line, and the lateral line is slightly curved. The hard spines of the dorsal fin are thick and smooth, and the caudal fin is forked. Chinese knotfish belo...
