Examples of Silver Carp and Bighead Carp Culture in Cage
The number of fish stocking in cages is reasonable and correct, and should be determined according to specific conditions. Generally speaking, running water, high dissolved oxygen in the water cage, can be put more. The water body is stable, the wind wave is small, and the oxygen in the water body is small. That is to say, the oxygen in the cage can make each fish have great satisfaction, that is, the limit of stocking quantity. If oxygen does not meet the fish's needs, it means overstocking. In fertilizer water (transparency is 25~30 cm) at the breeding silver carp, bighead carp can not feed. In general, stocking levels can be varied as follows

Do bighead carp eat phytoplankton?
Bighead carp mainly feed on zooplankton, but also feed on phytoplankton. According to Professor Ni Dashu's research, the average ratio of zooplankton to phytoplankton in bighead carp food is 1: 4.5. Phytoplankton is dominant in quantity, but its biomass is far less than that of zooplankton. On average, one zooplankton is 10 times or more larger than one phytoplankton. Therefore, from the bighead carp feeding habits analysis, phytoplankton occurrence rate is not low, but the main role in nutrition is still zooplankton. According to this situation, the original Guangdong experience still has room for improvement, namely bighead carp and silver carp.

Feeding of grass silver carp and bighead carp in autumn and winter
The breeding of parent fish is an important link in the artificial reproduction of green, grass, silver carp and bighead carp. The feeding and management in autumn and winter directly affects the effect of spawning in the second year, so full attention must be paid to it. 1. Conditions and cleaning of fish ponds. The fish ponds for breeding parent fish should not only be close to the spawning pond but also have good water source conditions, and it is convenient for irrigation and drainage. The bottom of the pond is less silt, silver carp and bighead carp ponds with a depth of 20 centimeters is enough, green and grass carp ponds should contain little or no silt. The area is 2000,3300 square meters and the water depth is about 1.5 meters. Parent fish cultivation

Mixed culture technique based on silver carp and bighead carp
Filter-feeding fish such as silver carp and bighead carp are mainly cultured, and other fish are properly mixed, with special attention to fish that eat organic decay debris. In the process of feeding, the method of applying farm manure is mainly adopted. 1. The stocking amount of silver carp and bighead carp accounts for 70% to 80%, and the output accounts for 60% to 70%. The large size fish species are solved by the method of fish pond culture. Silver carp and bighead carp species began to be caught in rotation in May, 6 to 7 times a year, and the size of fish species was enlarged immediately after the rotation, and the number of species released was generally equal to that caught. 2.

Processing of silver carp and bighead carp
Silver carp and bighead carp among the "four major fishes" are often sold poorly due to more spines between muscles and taste inferior to other fish.

Prevention and treatment of hemolytic ascites disease of bighead carp
With the gradual popularity of bighead carp in the market, most of the ponds in the suburbs of our city have changed from raising bighead carp to raising bighead carp. The yield of bighead carp has grown from dozens of jin per mu at the time of interculture to over 1000 jin per mu at the time of main culture. Due to the increase of bighead carp culture density, the incidence of bighead carp has also increased year by year, and the number of deaths has increased year after year, causing certain economic losses to farmers. Hemolytic ascites disease of bighead carp is a fulminant infectious disease, also known as bacterial septicemia, which is caused by bacteria.
