Embodiment 1

[0032] A high-efficiency breeding method for grass carp, comprising the following steps:

[0033] Step 1: Pond Construction and Retrofit

[0034] The area of ​​the pond is 10 mu, the depth of the pond water body is 1.8 meters, and each 2 mu of pond is equipped with an aerator with a power of 1 kilowatt and an automatic bait feeding machine;

[0035] Step 2: Pond Treatment

[0036] 10 days before the fish species are stocked, inject 0.15 meters of water into the pond, and carry out disinfection treatment according to 100kg of quicklime per mu. After 4 days, inject water into the pond again, so that the water in the pond reaches 2 meters;

[0037] Step 3: Fingerling stocking

[0038] Choose fish species with neat specifications, complete body surface, no deformities, no diseases and no injuries. The fish species should be soaked with 1% salt for 10 minutes before putting them in. The mass ratio of grass carp, silver carp and carp is 8: 1:1;

[0039] Step 4: Feed feeding

Embodiment 2

[0051] Step 1: Pond Construction and Retrofit

[0052] The pond area is 15 mu, the depth of the pond water body is 2.0 meters, and each 2 mu of pond is equipped with an aerator with a power of 1 kilowatt and an automatic bait feeding machine;

[0053] Step 2: Pond Treatment

[0054] 10 days before the fish species are stocked, inject 0.18 meters of water into the pool, and carry out disinfection treatment according to 100 kg of quicklime per mu. After 4 days, inject water into the pool again, so that the water in the pool reaches 2.2 meters;

[0055] Step 3: Fingerling stocking

[0056] Choose fish species with neat specifications, complete body surface, no deformities, no diseases and no injuries. The fish species should be soaked in 1.5% salt for 10 minutes before putting them in. The mass ratio of grass carp, silver carp and carp is 8: 1:1;

[0057] Step 4: Feed feeding

[0058] The feed to be fed is pellet feed. When feeding each meal, 60-70% of the fish will leave and...

Embodiment 3

[0069] A high-efficiency breeding method for grass carp, comprising the following steps:

[0070] Step 1: Pond Construction and Retrofit

[0071] The pond area is 20 mu, the depth of the pond water body is 2.2 meters, and every 2 mu of ponds is equipped with an aerator with a power of 1 kilowatt and an automatic bait feeding machine;

Abstract

The invention discloses a high-efficiency breeding method of grass carp, and relates to the technical field of aquaculture. The method comprises the following steps: step 1, construction and transformation of a pond; step 2, pond treatment; step 3, stocking of fry; step 4, feed throwing; step 5, breeding management; step 6, regulation and control of water quality; and step 7, proper fishing. According to the method disclosed by the invention, on the basis of zero water exchange of aquaculture water, carbohydrates are artificially added, so that mass propagation of endogenous microorganisms inthe water in the pond is promoted; and the endogenous microorganisms are utilized to assimilate inorganic nitrogen, the endogenous microorganisms are converted into mycoprotein, so that harmful nitrogen sources such as ammoniacal nitrogen and nitrite nitrogen in the culture pond are reduced, and the water quality environment of the culture pond is improved; and meanwhile, heterotrophic bacteria are subjected to further flocculation to form microbial flocculation clusters, the microbial flocculation clusters are eaten by carp and hypophthalmichthys molitrix, and the method has the effects of regulating and controlling water quality, promoting recycling of nutrients and improving a survival rate of the grass carp on the basis of water saving, energy saving and emission reduction.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a high-efficiency cultivation method for grass carp. Background technique [0002] With the continuous development of the modern economy and the improvement of living conditions, people's demand for food is also increasing, especially meat, such as fish, duck, and chicken, which are all ingredients on people's tables. Nutrient intake, which makes more and more meat farming manufacturers. [0003] Grass carp has the advantages of strong adaptability, fast growth, large individuals, wide feeding habits, few diseases, and delicious meat. It is suitable for enclosure in ponds, reservoirs, and lakes. It is a breeding species with good economic and social benefits. Due to the above-mentioned advantages of grass carp, it is easy to become a food item on the table. At present, most of the cultivation of grass carp follows the traditional pond culture mode of changing water. [0004...
