Problems solved by technology

[0002] At present, silver carp are mainly cultured in fish ponds and in large water surfaces. The yield of these two farming methods is very low, and the yield per mu is between 220 and 400 catties.
Moreover, silver carp cultured in general fish ponds are not good in size and taste, and the breeding area on large water surfaces is decreasing every year.
Long-term breeding will also lead to poor water quality, many fish diseases, and high fry mortality

Embodiment Construction

[0015] A culture method for silver carp, comprising:

[0016] (1) Pond selection: The fingerling pond has an area of ​​3-4 mu and a water depth of 1.8-2.5 meters. Before stocking fish fry, apply organic fertilizers for 15-20 days of cultivation, and use quicklime for disinfection;

[0017] (2) Fish species management: Manually feed fish feed at fixed points, timing, and quantity every day, and the amount of each feeding is counted as 80% of the fish leave the feeding point;

[0018] (3) Feeding and management: On the second day after the fish fry are put in, transplant the hydra to the pond, set up six circular fences with a diameter of 1 meter at equal distances in the pond, and transplant the hydra to the inside of the circular fence;

[0019] (4) Disease prevention and control: Sprinkle 10ppm quicklime every 20-25 days from April to September, and sprinkle 10ppm quicklime every 35-40 days in other months;

[0020] (5) Appropriate fishing: fish up to 1.1kg are caught once a...

Abstract

The invention discloses a chub culturing method comprising steps of (1) choosing a fish pond, (2) managing fish fingerlings, (3) managing breeding, (4) preventing diseases and (5) catching in a proper way. Compared with the present chub culturing technology, the chub culturing method has obvious advantages. In the culturing method, fish fries density is rationally arranged, so chub yield can be improved to the largest extent; and chub quality can be guaranteed. Six annular guardrails are arranged and black algae are transplanted, so water quality can be purified and chub food can be provided; solid and fresh chub fish meat can be achieved; and the black algae is blocked by the annular guardrails, so random growth of the black algae can be prevented and water body oxygen deficit due to the growth of the large scale black algae can be avoided. Medicine and forge use can be reduced; and the chubs cultured by the method have high quality and is free of pollution, so chub survival rate can be improved.

Description

technical field [0001] The invention relates to the field of cultivation, in particular to a method for cultivating silver carp. Background technique [0002] Currently silver carp are cultured mainly in sets of fish ponds and in large water surfaces. The yields of these two culture methods are very low, ranging from 220 jin to 400 jin per mu. Moreover, silver carp cultured in general fish ponds are not good in size and taste, and the aquaculture area in large water surfaces is decreasing every year. Long-term breeding will also lead to poor water quality, many fish diseases, and high fry mortality. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies, the invention provides a method for cultivating silver carp. [0004] The present invention is realized through the following technical solutions: [0005] A culture method for silver carp, comprising: [0006] (1) Pond selection: The fingerling pond has an area of ​​3-4 mu and a water...
