Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the examples.

[0023] The basic steps of the method of the present invention are as follows:

[0024] 1. Pond selection

[0025] Ponds generally choose seaside cofferdam ponds, which are required to be close to sea areas with good water quality, rich natural bait, and distribution of wild hexaline carp, and should be close to the hexaline carp nursery. The pond is generally suitable for 20-50 mu, with convenient water intake and drainage, water depth of 2.5-3 meters, and a complete gas supply system.

[0026] 2. Cage settings

[0027] The size of the breeding cage is 4m x 4m x 2.5m, and the bottom is anchored to prevent the net from moving with the water flow and scratching the broodstock. The net cages are set in a "field-shaped" or "chain-shaped" configuration to facilitate inspection of broodstock. 4 aeration stones are set at the bottom of each cage to ensure that the dissolved oxygen i...

Abstract

The invention provides a pond cage cultivation method for parent fish of hexagrammos otakii, solving the problem of low cultivation success rate of the parent fish of the hexagrammos otakii. The cultivation success rate of the wild parent fish is increased to 47.4%, offspring seed quality and production capacity are improved, and a feasible solution is provided for cultivation of the wild parent fish of marine fishes. Some parent fish lay eggs in pond cages naturally, so that complex operations such as manual egg collection and insemination are omitted, working strength of manual reproductionprocesses is lowered, and large-scale offspring seed production is benefited.

Description

technical field [0001] The invention belongs to the technical field of fish breeding, and in particular relates to a method for cultivating wild broodstock pond cages of Otaki hexalis. Background technique [0002] Hexagrammos otakii, also known as Hexagrammos otakii, also known as Hexagrammos otakii, commonly known as yellow croaker, belongs to the order Scorpaeniformes, the family Hexagrammidae, and the genus Hexagrammos. Sexual offshore demersal reef fish. It is mainly distributed along the coasts of the Yellow Sea and the Bohai Sea, and is also found in the seas of North Korea, Japan and the Far East of Russia. This fish is resistant to low temperature, and its survival temperature is 2-26°C. In China, it is mainly produced in coastal rocky sea areas such as Shandong and Liaoning. Its tender meat and delicious taste are known as "Northern Grouper". It is deeply loved by consumers and has high economic value. Dataki hexaline is an ideal species for cage culture in nort...
