Example Embodiment

[0050] Example 1

[0051] A breeding method for reducing gill rot disease of carp, including the following steps:

[0052] (1) Fish pond cleaning: Choose a pond with an area of ​​4 mu, a pond depth of 1.8 meters, and a silt thickness of 8 cm as the fish pond. 7 days before the fry enter the pond, use quicklime to clean the pond and set the water inlet. And the drainage ditch, and then add clean river water to the fish pond. The depth of the river water is half that of the fish pond, and the inlet and outlet are closed. The dissolved oxygen content in the water is 6mg / L;

[0053] (2) Fry selection: The fry must be inspected and quarantined before stocking. Choose pure quality, healthy, disease-free, and neat specifications;

[0054] (3) Put the fry: choose the early morning in sunny weather, the temperature of the fish pond is 16 degrees Celsius, put the fry in a plastic bag with oxygen, and then put the fry together with the plastic bag into the upper wind of the fish pond to release ...

Abstract

The invention belongs to the technical field of aquaculture, and relates to a breeding method capable of reducing a gill-rot disease of carps. The method comprises the following steps: (1) cleaning afish pond; (2) selecting fries; (3) throwing the fries; (4) throwing feed and performing later-period management: stocking juvenile fish, 1-2 weeks before the juvenile fish are subjected to stocking,performing feeding by throwing powdery mixed feed composed of rice bran meal, rapeseed meal and wheat bran powder according to a weight ratio of 1:2:0.5 for 2 times every day, wherein a daily feedingamount is 2-3% of a body weight of the fish, after 2 weeks, performing feeding by throwing carp feed for 2-3 times every day, wherein a daily feeding amount is 2.2-3.5% of a body weight of the fish, and injecting water into the fish pond once every 5-7 days, wherein a water adding amount is 10-15 cm of a height of the fish pond every time; and (5) preventing and controlling a fish disease. Experiments prove that the method provided by the invention can significantly reduce an incidence rate of the gill-rot disease of the carps, improve a survival rate of breeding, and increase breeding incomes.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a culture method for reducing gill rot disease of carp. Background technique [0002] Carp has the advantages of fast growth, good meat quality, and strong fecundity. Acute gill rot of carp is an acute infectious disease that is more common in carp farming in recent years. , causing huge economic losses to aquaculture production. The onset of acute gill rot in carp is rapid. At the beginning of the onset, some carp have "dark floating head" or roaming phenomenon, and their breathing is slow. Moreover, when the onset occurs, the eating conditions of the fish are basically normal. On the first day of the disease, 3-5 carps will die sporadically in a small amount. From the second day onwards, the carp death rate increases rapidly. The carp with the disease is fished out and observed. There is no obvious abnormality on the body surface. There are white spots on the ...
