[0003] Based on this, if you want to get more high-quality koi, you need to breed high-quality koi broodstock. Therefore, the broodstock must not only be pure in appearance, but also have a healthy body and a high maturity rate. This requires strengthening the broodstock with better traits. Cultivation is conducive to hatching in the coming year, and the relevant methods for the intensive cultivation of koi broodstock in the prior art are still blank

Embodiment 1

[0020] A kind of broodstock intensive cultivation method of koi carp comprises the following steps:

[0021] (1) Selection of broodstock pond: The pond area is 1 mu, the pond water depth is 1.8 meters, and the pond slope ratio is 1:2.5. In case of fish invasion or broodstock escape, the water source is non-polluted groundwater. Aquatic plants are planted in the pond to provide concealment conditions for the broodstock. The bottom of the pond is flat and the water retention is good.

[0022] (2) Clear pond and fertilizer water in the pond: After draining the water in the pond, sprinkle quicklime evenly on the bottom of the pond to clear the pond completely. After 4 days, pour water into the fish pond to a water depth of 25cm, and use self-prepared disinfectant to disinfect , the preparation method of the disinfectant is to mix tea seed cake with 2.5% sodium chloride solution and soak for 2 hours, then stir, and the application density is 3kg per mu; 7 days before the koi enters...

Embodiment 2

[0029] A kind of broodstock intensive cultivation method of koi carp comprises the following steps:

[0030] (1) Selection of broodstock pond: The pond area is 1.2 mu, the pond water depth is 2 meters, and the pond slope ratio is 1:2.8. In case of fish invasion or broodstock escape, the water source is non-polluted groundwater. Aquatic plants are planted in the pond to provide concealment conditions for the broodstock. The bottom of the pond is flat and the water retention is good.

[0031] (2) Clear pond and fertilized water in the pond: After draining the water in the pond, sprinkle quicklime evenly on the bottom of the pond to clear the pond completely. After 6 days, pour water into the fish pond to a depth of 35cm, and use self-prepared disinfectant to disinfect , the preparation method of the disinfectant is to mix tea seed cake with 2.5% sodium chloride solution and soak for 2 hours, then stir, and the application density is 3.2kg per mu; 8 days before the koi enters the...

Embodiment 3

[0038] A kind of broodstock intensive cultivation method of koi carp comprises the following steps:

[0039] (1) Selection of broodstock pond: The pond area is 1.5 mu, the pond water depth is 2.2 meters, and the pond slope ratio is 1:3. In case of fish invasion or broodstock escape, the water source is non-polluted groundwater. Aquatic plants are planted in the pond to provide concealment conditions for the broodstock. The bottom of the pond is flat and the water retention is good.

[0040] (2) Clear pond and fertilized water in the pond: After draining the water in the pond, sprinkle quicklime evenly on the bottom of the pond to clear the pond completely. After 6 days, pour water into the fish pond to a depth of 35cm, and use self-prepared disinfectant to disinfect , the preparation method of the disinfectant is to mix the tea seed cake with 2.5% sodium chloride solution and soak for 2 hours, then stir, and the application density is 3.5kg per mu; 10 days before the koi goes ...

Abstract

The invention discloses an intensified cultivation method of parent koi fishes. The intensified cultivation method comprises the steps of 1, selection of a parent fish pool; 2, cleaning and water fertilizing for the pool; 3, selection of the parent fishes; 4, preparation before putting of the parent fishes into the pool; 5, intensified cultivation; 6, daily management; 7, gonad development and regulation. According to the intensified cultivation method, adopted pool cleaning chemicals contain natural ingredients, and the killing effect is significant; utilized organic fertilizer is simple in formula and easy to obtain, and rich plankton can be generated in the fish pool within a short term, and can serve as food for the parent koi fishes in the early stage and inhibit the reproduction and growth of harmful organisms. According to the method, by controlling the feed putting amount according to seasons, the types of the put feed and the content of nutritional ingredients of the put feed are adjusted at the same time, length and weight increase of the parent koi fishes can be sufficiently facilitated, and the stress resistance of the koi fishes is improved; by adjusting the water temperature and illumination intensity acceptable to fish bodies, the gonad development of the parent koi fishes and the stability of the water environment are promoted.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for intensively cultivating koi broodstock.
