Ecological grass carp breeding method

Abstract

The invention relates to a freshwater fish breeding technology, in particular to an ecological grass carp breeding method.The method includes the following steps of appropriate pond selection, pond cleaning and arranging, fry stocking, water quality management, breeding management, disease and pest prevention and fishing.By means of the method, the breeding quality and yield of grass carps can be improved, grass carps bred through the method are fresh in meat taste and good in taste, scientific breeding management can be achieved, health care is achieved, disease and pest prevention is achieved at the same time, disease and pest prevention is thorough, the disease control rate reaches 100%, and the method is ecological, environmentally friendly, low in production cost, high in economic benefit and suitable for large-scale production.In the grass carp breeding process, through the green grass and biological fermentation feed mixed putting mode, the quality of grass carps is remarkably improved, the technology is simple, the investment cost is low, risks are small, operability is high, and the method is easy to grasp and apply and easy to popularize and promote.

Description

technical field [0001] The invention relates to a freshwater fish culture technology, in particular to a grass carp ecological culture method. Background technique [0002] Grass carp belongs to the genus Grass carp of Cyprinidae, Cyprinidae, Yaluo subfamily, grass carp, and the common names of grass carp are: grass carp, oil carp, grass carp, white carp, grass carp, grass root (Northeast), mixed son, black herring, etc., English name: Grasscarp, Inhabiting rivers and lakes in plain areas, they generally prefer to live in the middle and lower layers of the water and areas with many aquatic plants near the shore. They are lively, swim quickly, and often forage in groups. They are typical herbivorous fish. Grass carp eats larvae when they are young. Algae, etc. Grass carp also eat some meat, such as earthworms, dragonflies, etc., overwinter in the deep waters of main streams or lakes, and the broodstock have the habit of swimming in the breeding season, and have been transplante...

AI Technical Summary

Problems solved by technology

However, at present, the pond water is in a stagnant state, and the water quality is easy to deteriorate; the taste of grass carp fed with artificial concentrated feed is worse than that of natural grass carp, the meat quality is loose, and the umami taste decreases; while the grass carp fed with pure green feed has a long growth cycle, which cannot meet the needs of the market. need

When the grass carp is raised in monoculture, the species is single, the pond space and bait are not fully utilized, and the benefit is low. When the grass carp is mixed, it is necessary to choose a reasonable species and quantity, which is in line with the ecological cycle of the pond.

[0004] In addition, in recent years, with the large-scale rise of grass carp farming, it was found during the breeding process that due to the lack of reasonable and effective feeding methods, the quality and quantity of grass carp cultivation have decreased significantly. , use more chemical compounds, antibiotics, etc. to help grass carp grow too fast or to solve the impact of various diseases and insect pests in the growth process of grass carp, although the breeding time of grass carp is greatly shortened or in a very short period of time The impact of pests and diseases has been controlled within a short period of time, but on the other hand, the quality of grass carp has changed. More importantly, after the use of chemical drugs or antibiotics, the drugs remain in the body of grass carp and will be transferred to the human body during human consumption. , which will affect people's health, and the use of chemicals or antibiotics will pollute the environment, which is not conducive to ecological protection

[0005] Thirdly, grass carp is gluttonous, eating too much will cause gastrointestinal problems, etc. If active and effective feed methods are not adopted, it will bring a burden to the gastrointestinal tract of grass carp, causing them to suffer from gastrointestinal problems and affecting the healthy growth of grass carp
