Zhongke No. 5 crucian carp fry has the characteristics of tight scales, difficulty in shedding scales, fast growth rate, high meat production rate, low incidence rate and high survival rate. It is suitable for use in warm and muggy weather. When raising, in order to prevent it from flooding the pond due to hypoxia, you should insist on patrolling the pond every morning to replenish oxygen in time. You can also plant aquatic plants in the water, which can not only increase the content of trace elements, but also provide abundant plankton so that crucian carp can feed freely. .

1. Characteristics of Zhongke No.5 crucian carp fry

1. Characteristics

Zhongke No.5 crucian carp fry has a silver-black body color, tight scales, and is not easy to fall off. It has the characteristics of large scales, fast growth rate, high meat production rate, low incidence rate and high survival rate.

2. Breeding precautions

(1) Insist on patrolling the pond in the morning, noon and evening, carefully observe the water quality of the pond and the feeding and health conditions of crucian carp. If the disease is discovered, timely treatment should be carried out .

(2) Insist on frequent water changes, frequent oxygenation, frequent prevention and frequent fishing, especially in warm and muggy weather, and insist on patrolling the pond every early morning to prevent fish from flooding the pond due to lack of oxygen.

(3) Aquatic plants or algae can be planted in the water, which can not only increase the content of certain trace elements, but also provide abundant plankton for crucian carp to feed freely.

(4) Control the breeding density, and control the density of adult fish per mu of breeding pond to about 1,500-1,700 fish.

(5) The size of the feed needs to be controlled. Small feed will easily cause the feed to dissolve in the water, which is not conducive to the feeding of young fish. If the feed is too large, the young fish will not be able to eat. The feed should be in powder form, because the young fish will eat collectively and the feed will dissolve in time without causing waste.

(6) For crucian carp weighing 50-250g, the feed size should not exceed 0.2cm. For crucian carp weighing more than 250g, the feed size should be controlled at about 0.3cm.

2. How big can Zhongke No.5 crucian carp fry be raised in one year?

3. To prevent and treat fish diseases, 2.5% trichlorfon powder can be sprinkled throughout the pond 1-2 days before the crucian carp species are put into the pond to make the pond water 1ppm.
