Problems solved by technology

[0003] In order to meet the growing demand for grass carp, people have to increase the supply by means of artificial breeding. In order to increase production, most breeders prepare some feed containing hormones or various additives to promote growth, and at the same time use a large amount of antibiotics to prevent Fish are sick. Although this can effectively increase fish production, the taste and nutritional value of the produced fish will be greatly reduced, far inferior to wild grass carp

Embodiment 1

[0030] A method for imitating wild cultivation of grass carp, comprising the steps of:

[0031] (1) Pond construction:

[0032] Select the land with sufficient water source and convenient transportation to build a pond with an area of ​​8 mu. The depth of the control pond is 2.8 m, the length-to-width ratio of the pond is 3:2, the slope ratio of the pond is 1:2.6, and the bottom mud thickness of the pond is 20cm. Exposure to the sun without irrigation for 3 days, then inject water with a depth of 35cm, disinfect with 100kg of quicklime per mu, add water to a depth of 2.3m after 3 days, and finally plant bitter grass, hydrilla, duckweed and watery weed in the pond, The total area planted is 30~35% of the pond;

[0033] (2) Fry selection for stocking:

[0034] Select grass carp seedlings with strong physique, neat specifications, no disease and no injury, first soak and wash them in salt water with a mass concentration of 4% for 10 minutes, and then stock them in ponds with a ...

[0056] A method for imitating wild cultivation of grass carp, comprising the steps of:

[0057] (1) Pond construction:

[0058] Select the land with sufficient water source and convenient transportation, build a pond with an area of ​​10 mu, control the depth of the pond to 2.5m, the ratio of the length to width of the pond to 3:2, the ratio of the slope to the pond to 1:2.6, and the thickness of the bottom mud of the pond to 18cm. Exposure to the sun without irrigation for 3 days, then inject water with a depth of 40cm, disinfect with 110kg of quicklime per mu, add water to a depth of 2m after 4 days, and finally plant bitter grass, hydrilla, duckweed and watery greens in the pond, and plant The total area of ​​the pond is 25~30%;

[0059] (2) Fry selection for stocking:

[0060] Select grass carp seedlings with strong physique, neat specifications, no disease and no injury, first soak and wash them in salt water with a mass concentration of 2% for 12 minutes, and then stoc...

Abstract

The invention discloses an imitated wild breeding method for grass carp and belongs to the field of aquaculture. The method comprises the following steps: (1) constructing a pond; (2) selecting and stocking fingerling; (3) managing feeding; (4) performing daily managing. According to the method provided by the invention, the drug ingredients, including hormone, antibiotics and the like, are not added in the whole breeding process; a safe and healthy environment is supplied for the growth of the grass carp; the reasonably prepared special fertilizer can meet the nutrient requirements of the grass carp in all growth stages; the lastly bred grass carp is high in yield, tastes nice, is balanced in nutrition, has the quality similar to that of the wild grass carp and is very strong in market competitiveness.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a method for imitating wild cultivation of grass carp. Background technique [0002] 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 national annual output is more than 4 million tons. It is one of the important freshwater farmed fish in my country. There are few intermuscular thorns and are much loved by consumers. Undoubtedly, the nutritional value of wild grass carp is very high, and it is also natural and harmless. It is because of this that people wantonly catch it, resulting in a sharp decrease in the amount of natural wild grass carp, and the supply exceeds demand. [0003] In order to meet the growing demand for grass carp, people have to increase the supply by means of artificial breeding. In order to increase production, most breeders prepare some f...
