Embodiment 1

[0026] A breeding method for red and white koi, comprising the following steps:

[0027] (1) Conditions of aquaculture ponds: the selected area of ​​aquarium ponds is 2000-3500m 2 , An earthen pond with a depth of 180-250cm or an area of ​​50-100m 2 , A cement pool with a pool depth of 120-150 cm. Necessary filtration equipment, lighting equipment and constant temperature equipment should be installed in the fish pond. Before the new fish enter the fish pond, the beneficial bacteria should be cultivated. Add water to the fish pond and add an appropriate amount of nitrifying bacteria every day for 3 consecutive days to balance the nitrifying bacteria and beneficial bacteria in the fish pond. , Inhibit the growth of harmful microorganisms in the pool, and prevent the occurrence of diseases after new fish enter the pool. Breeding water needs to be fresh and free from any pollution, with a pH of 7-8.5, DO above 5.0 mg / L, and a total hardness of 2-3 mg equivalent / L. The seedling...

Abstract

The invention discloses a red-white fancy carp breeding method which includes the steps: (1) fry stocking; (2) feed feeding; (3) red-white fancy carp fry selection: selecting red-white fancy carp fries growing to 3-5cm for the first time, removing deformed fries, all-red fries and all-white fries, selecting the red-white fancy carp fries growing to 8-10cm for the second time, and removing the fries with red heads and incomplete deep red patterns, fries with less than 20% of whole-body red patterns, fries with deviated red patterns and fries with 60% or more of gravel point red patterns. According to the red-white fancy carp breeding method, the commercial quality and the breeding survival rate of red-white fancy carps can be effectively improved, breeding period is shortened, the average breeding survival rate reaches 86.7%, grade commercial fishes are high in proportion, and the proportion of A-grade commercial fishes reaches 75.8% or more. In addition, the breeding period is shortened by 6.5-8.5 months (the breeding period of the method is 3-4 years), so that breeding cost is reduced, and breeding benefits are improved.
