CATDOLL : CATDOLL: How to raise silver carp, silver carp breeding technology

1. Preparation before stocking: The area of ​​the fish pond should be relatively large, generally 4-8 mu, and the water should be deep, generally 1.5-2 meters. Organic fertilizer should be applied before stocking for cultivation. For silver carp, the base fertilizer should be applied in appropriate amounts, and the peak period of wheel worms should be controlled.

2. Summer flower stocking: The stocking time is generally from May to June. There are two stocking methods: single stocking and mixed stocking. Generally, mixed stocking is adopted because the habits of fish at this stage gradually show different requirements for the external environment. According to the habits of various fish and their adaptability to water quality, mixed stocking is carried out. It not only provides a suitable growth environment for various fish, but also fully utilizes the water body and makes more economical use of food. Fish ponds generally have 2-3 species of mixed stocking. In this experiment, a small amount of silver carp and carp are mixed.

3. Feeding and management: At this time, silver carp still mainly feed on plankton. The pond water should be fertile and have a large amount of plankton. In addition to applying basal fertilizer before stocking, green manure and mature manure should be applied after stocking summer carp. Combined with regular injection of new water, the water should remain brown-green. When feeding artificial hunger lead fiber, pay attention to the "four fixed" principles, namely, timing, positioning, quality and quantity, in order to improve the utilization rate of bait and reduce the bait coefficient. At this time, the amount of bait should be less.

4. Daily management: Patrol the pond once every morning, observe the water color and the dynamics of the fish, regularly remove weeds by the pond and rotten debris in the water, clean the feeding table and disinfect the feeding table and food to protect the hygiene of the pond; pull the net to check not only to enrich the water, but also to check the growth of fish and fish diseases, so as to reasonably determine the amount of feed and the method of fish disease prevention and control, and do a good job in preventing escape, theft, fish diseases and predators.
