Embodiment Construction

[0022] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0023] A method for artificially induced spawning of silver arowana, comprising prenatal cultivation of silver dragon fish parent fish and artificial induced spawning of silver dragon fish, the main steps are as follows:

[0024] (1) Prenatal breeding of silver dragon fish broodstock:

[0025] (101) Preparation of the aquarium. The silver dragon fish is a large and robust fish species. The volume of the aquarium for cultivating silver dragon fish must be larger than 1.5m*1m*0.8m. The aquarium is equipped with an oxygenation pump and a circulation filter in the tank , heating pipes and fishing nets, the water source in the aquarium is tap water that has been exposed to sunlight for more than 3 da...

Abstract

The invention discloses an artificial spawning method for osteoglossum bicirrhosum. The method comprises the steps of the antenatal cultivation of parent fish of the osteoglossum bicirrhosum and the artificial spawning process of the osteoglossum bicirrhosum. According to the method, it is ensured that the osteoglossum bicirrhosum can obtain more germ cells, the hatchability of the germ cells and the survival rate of the fish fry are both high, breeding of the osteoglossum bicirrhosum in the northern China is achieved, and the high economic value is obtained.

Description

technical field [0001] The invention relates to a method for inducing spawning of fish, in particular to a method for artificially inducing spawning for silver arowana. Background technique [0002] Silver arowana, also known as the double-spined bone fish, belongs to the Osteoglossidae family. It is an important economic fish in the local rivers and lakes in Guyana and the Amazon River in South America. It is also a popular and worldwide tropical freshwater ornamental fish. . The silver arowana has a long strip-shaped body, flat sides, a fan-shaped tail, a strip-shaped dorsal and anal fin, and extends backwards to the base of the caudal peduncle. The lower jaw is more protruding than the upper jaw, with a pair of short and thick beards. Five rows of large scales are neatly arranged on its wide fish body, shining silvery light under the light. Each fin reflects a bright red or orange luster under light. Juvenile body color is blue; dorsal and anal fins have red-blue edge...
