Embodiment Construction

[0019] A method for hatching a net cage in a cement pond of wheat ear fish, comprising the following steps:

[0020] (1) Source and cultivation of broodstock

[0021] Broodstock should be selected from artificially caught wild parents and a small number of pond-bred parents. The broodstock should be well-developed, healthy, disease-free and injury-free, weighing >3g, body length >500mm, and over 2 years old;

[0022] The parents are collected and cultivated intensively. The area of ​​the cultivation pond is 667m 2 , the water depth is 1.2m. During the cultivation period, fish and insects are fed quantitatively every day, and a small amount of new water is added every 3 days.

[0023] (2) Spawning ponds and hatching facilities

[0024] The spawning pool is an ordinary circular cement pool with a diameter of 7m and a depth of 2.5m. There is an aeration device at the bottom. It is disinfected with disinfectant water one week before induced labor. The water depth is 60cm. The ha...

The method comprises the steps of: source and cultivation of parent fishes, spawning pond and incubation facilities, induced spawning and ovulation, incubation and the like. The method provided by the invention can improve the disease resistance of pseudorasbora parva fry and enhance incubation rate, survival rate and emergence rate, is simple in operation, small in investment and large in output, provides technical base for the intensification, industrialization, large scale and quality of the pseudorasbora parva fry, and has enormous economic benefits.

Description

technical field [0001] The invention relates to a method for hatching net cages in cement ponds of oysters, and belongs to the technical field of aquaculture. Background technique [0002] Pseudoroasbora parva belongs to Cyprinidae, Cyprinidae, Pseudoroasbora, and Pseudoroasbora genus. It is widely distributed in fresh water and commonly found in major water systems in eastern China. Alias: Arhat fish, Ma Nenzi, mixed croaker, etc. In recent years, with the improvement of people's living standards, the consumption of freshwater fish no longer stays on the traditional four major fish. Consumers pursue fewer spines, more meat, and delicious taste. The wheat ear fish undoubtedly meets the above characteristics. At present, there are few reports about hatching in artificial breeding of chrysalis. Contents of the invention [0003] The purpose of the present invention is to provide a method for hatching a net cage in a cement pond of chrysalis, which provides basic data for t...
