Embodiment 1

[0016] 1. Selection of broodstock: 160kg of healthy and mature broodstock of Channa sinensis was purchased in the waters near Dongxing, Guangxi, including 83kg of female fish and 77kg of male fish, with a male-to-female ratio of 1.1:1. Soak the broodstock in fresh water for 10 minutes to remove body surface dirt and fish lice, and separate the male and female broodstock into different holding ponds. The depth of the holding pond is 60cm, and the bottom area is 10m 2 , Ceramic tubes are placed in the pool, and each ceramic tube can accommodate 5 to 10 broodstock, keeping the running water inflated state, and the specific gravity of seawater is 1.012. Feed fresh shrimp on the first day, fresh fish on the second day, and stop eating on the third day to prepare for induction of labor.

[0017] 2. Artificial induced labor: In the afternoon of the fourth day, induce labor by injection, and put the broodstock after the induced labor into the spawning pool where the ovaries have been ...

Embodiment 2

[0024] 1. Selection of broodstock: 120kg of healthy and mature broodstock of Channa sinensis was purchased in the waters near Fangcheng, Guangxi, including 49kg of female fish and 71kg of male fish, with a male-to-female ratio of 1:1. Soak the broodstock in fresh water for 10 minutes before entering the pond to remove body surface dirt and fish lice, and separate the male and female into different holding ponds. The holding pond specifications are the same as in Example 1, with a water depth of 55 cm and a bottom area of ​​10 m 2, Ceramic tubes are placed in the pool, and each ceramic tube can accommodate 5 to 10 broodstock, keeping the running water inflated state, and the specific gravity of seawater is 1.012. Feed fresh shrimp on the first day, feed fresh fish on the second and third days, stop eating on the fourth day, and induce labor on the fifth day.

[0025] 2. Artificial induction of labor: In the afternoon of the fifth day, injections were performed to induce labor, ...

Abstract

The invention discloses an artificial breeding method of Bostrichthys sinensis. Currently, only natural seedlings are used in the breeding of the Bostrichthys sinensis, and small-scale artificial breeding is successful, but has the defect that limited seedlings can be provided. In order to solve the problem of shortage of Bostrichthys sinensis seedlings, technical measures including parent fish selection, induced spawning, artificial incubation and fish fry breeding are adopted in the artificial breeding method, and a large-scale artificial breeding technology of the Bostrichthys sinensis seedlings is searched. The artificial breeding method is scientific and reasonable in process flow and strong in operability. The large-scale artificial breeding of the Bostrichthys sinensis is realized, and weighted according to fertilized eggs, the breeding survival rate is up to over 58.5%. A technical support is provided for the large-scale industrial breeding of the Bostrichthys sinensis seedlings, and the defects of low technological content and small breeding amount of the conventional breeding method are overcome.

Description

technical field [0001] The invention relates to a breeding technique for marine fish seedlings, in particular to an artificial breeding method for Chinese snakehead, belonging to the field of aquaculture. Background technique [0002] Chinese snakehead Bostrichthys sinensis (Lacen~ede), commonly known as "snake" along the coast of Guangxi, and "mullet, mud fish or native fish" along the coast of Guangdong and Fujian, is a rare seawater fish with tender meat and nutritious Abundant, high-quality seafood, popular with domestic and foreign consumers, has the characteristics of long-term survival after leaving water, especially suitable for long-distance fresh transportation. Channa sinensis has strong adaptability to the environment, easy breeding, low risk, and high investment returns. It has always been the object of artificial mariculture in coastal areas of Guangxi, Guangdong and Fujian. Especially since the 1980s, the artificial breeding of Chinese snakeheads has develope...
