Problems solved by technology

However, feeding a large amount of high-protein and high-energy bait makes the grass carp passively change its feeding habits, and its body functions cannot adapt to the change of feeding habits for a while. If it eats bait that exceeds its nutritional requirements for a long time, the nutrition cannot be completely converted, and the body fat will accumulate too much. , leading to the symptoms of poor nutrition metabolism of grass carp, resulting in the decline of immunity and disease resistance of grass carp, and there are also problems such as the decline of fish meat quality and poor taste
[0006] In view of the high incidence of grass carp, the most common w

Embodiment 1

[0025] A farm in Nanhai District, Foshan City selected 1,000 healthy grass carp over 0.5 kg in uniform size, randomly divided them into 2 groups, and moved them into ponds for breeding. Group 1 was cultured according to the traditional method, all fed with compound feed; Group 2 was fed with mixed feed of Huangzhu grass and compound feed, the ratio was 1:1 (dry matter ratio), and every 4 days of continuous feeding, 3 days of fasting. Forty-five days before the grass carp goes on the market, mix and feed 1% of the self-made Chinese herbal medicine preparation in the compound feed. 10%, Shouwu San 10%. During the breeding process, the pH value of the water quality in the pond is controlled at 7-8.5, the transparency is 30-40cm, and the solubility is kept above 5mg / L. When harvesting at the end of the year, compared with group 1, the grass carp in group 2 has improved to varying degrees in terms of body color and muscle nutrition, and the price is 20-30% higher than similar prod...

Embodiment 2

[0040] Select healthy grass carp weighing more than 0.5 kg and move them into ponds for breeding. During the breeding process, the pH value of the water quality in the control pond is 7-8.5, the transparency is 30-40cm, and the solubility is kept above 5mg / L. Proportion). One month before the grass carp went on the market, 1% of the self-made Chinese herbal medicine preparation was mixed and fed in the compound feed. Eucommia 15%, Shouwu San 5%.

Embodiment 3

[0042] Select healthy grass carp weighing more than 0.5 kg and move them into ponds for breeding. During the breeding process, the pH value of the water quality in the control pond is 7-8.5, the transparency is 30-40cm, and the solubility is kept above 5mg / L. Ratio), every 4 consecutive days of feeding, 2 days of fasting. Two months before the grass carp went on the market, 1% of the self-made Chinese herbal medicine preparation was mixed and fed in the compound feed. Eucommia 5%, Shouwu San 15%.

Abstract

The invention provides a scientific culture method for Runchen fish and belongs to the technical field of aquatic product culture. This method does not change the growth period of grass carp and other breeding effect and adopts mixing feeding mode with grass and mixed feed so as to substantially improve the quality of grass carp; the method has simple technology, low investment cost, low risk, strong operationality, and is easy to grasp and apply and easy to promote.

Description

[0001] Technical field: [0002] The invention belongs to the field of aquaculture, and relates to a fish breeding method, in particular to a scientific breeding method of "Runchen fish". [0003] Background technique: [0004] Grass carp is a popular freshwater fish product, and it is an important source of high-quality and cheap animal protein in the daily diet of the Chinese people. The annual output in the country is more than 4 million tons, and it is one of the important freshwater farmed fish in my country. As the main herbivorous fish species raised in my country, the feeding habits of grass carp begin to transform to herbivore when the body length is 2.6cm. Aquatic grass and forage are the natural food that grass carp likes to eat, and they are also the main source of bait for traditional grass carp. [0005] In recent years, with the development of the feed industry, compound feeds have played a role in the cultivation of grass carp with high protein content, fast gro...
