Problems solved by technology

[0003] The traditional matching ratio of silver carp and bighead carp is 3:1, that is, 3 silver carp and 1 bighead carp, 75% and 25% respectively. According to production practice, in the stocking structure of silver carp and bighead carp, the proportion of bighead carp is less than 20% or silver carp The proportion of fish is greater than 80%, and the growth rate of bighead carp is relatively fast. When the stocking ratio of silver carp is between 20% and 80%, the growth rate of bighead carp

Example Embodiment

[0030] Example 1

[0031] A three-dimensional breeding method of bighead carp includes the following steps:

[0032] (1) Pond disinfection: Before stocking, control the pond to leave 5cm of water, and add quicklime at an amount of 60kg per mu, and dry it for 1d;

[0033] (2) Inoculation: The pond will evenly inoculate the pondweed and water lotus in the middle and around the pond, and the total inoculation area is 14% of the pond area;

[0034] (3) Bighead carp disinfection: Bighead carp is immersed in salt water with a concentration of 1% for 5 minutes before putting the bighead carp, and the difference between the salt water temperature and the pond water temperature is 0.5°C.

[0035] (4) Stocking management: Put the disinfected bighead carp into the pond, the stocking amount is 1,300 pieces per mu, and the size of the bighead carp is 40g / tail.

Abstract

The invention belongs to the technical field of breeding and particularly provides a stereo bighead carp breeding method. Bighead carp breeding is completed through the seven steps of pond sterilization, inoculation, bighead carp sterilization, stocking management, feed management, pond management and disease prevention and control, a water body environment is improved by inoculating pondweeds and water lettuce, nutrient substances are provided for bighead carps and distoechodon tumirostris, bighead carp growth and propagation are effectively promoted and the bighead carp yield is increased by adopting a bighead carp and distoechodon tumirostris polyculture method, nutrients are supplemented for bighead carp growth by combining feed usage, the immunocompetence of bighead carps is improved, and disease occurrence rate is reduced.

Description

technical field [0001] The invention belongs to the technical field of cultivation, in particular to a cultivation method for bighead carp. Background technique [0002] Bighead carp is also called silver carp, fat head fish, Baotou fish, big head carp, black carp, bighead carp, also called male fish, is a kind of freshwater fish, has the elegant title of "water scavenger", and is one of the four major fish in China; It looks like a round-nosed pomfret, with a flat body, a large and wide head, a wide mouth, and slightly upturned, and a relatively low eye position; bighead carp grows in freshwater lakes, rivers, reservoirs, and ponds. One of the main targets of fishery; bighead carp has high nutritional value, and its fish brain contains a kind of fish oil needed by the human body, and fish oil is rich in polyunsaturated fatty acids, which is an essential nutrient for the human body and can play a role To maintain, enhance and improve brain function, the meat under the gills...
