Chiniperca chuatsi is a specialty freshwater fish in China, belonging to the genus Siniperca chuatsi in the family Serranidae of the order Perciformes. Its flavor, high protein content, nutritious, is one of the valuable fish. Siniperca chuatsi is a fast-growing, high-yielding fish with high economic value. Siniperca chuatsi's reproductive season is generally from May to early July each year, and it likes to spawn in gently flowing water, with the amount of eggs each time between 60,000 and 200,000, and the eggs are floating eggs, as they are slightly heavier than water, and can follow the waves in the flowing water and continue to develop and grow. So today let's take a look at the live Mandarin fish culture has a lot of requirements, live Mandarin fish culture requirements have?

1. Choose a good aquaculture environment

The aquaculture area is recommended to be chosen far away from toxic and harmful places and sources of pollution or contaminants. The aquaculture area should have sufficient water supply, convenient drainage and irrigation, and no industrial "three wastes" pollution sources. The ponds for Mandarin fish should be cleared of excessive silt, and the ponds should be dried and exposed to sunlight, so that the substrate can be hardened.

2. Bait must be sufficient

Chiniperca chuatsi fish is a typical carnivorous ferocious fish, live fish and shrimp as bait is the feeding characteristics of Siniperca chuatsi fish, such as the lack of live bait fish, that is, eating each other, if a Siniperca chuatsi fish swallow another Siniperca chuatsi fish, it is possible to be stuck, resulting in the death of both fish. Insufficient bait fish can also cause the fish to become thin and weak, which will easily cause illness, affect growth and even starve to death. Therefore, it is important to supply sufficient quantity and appropriate size of bait fish under general culture conditions. Bait fish can be cultured in Mandarin fish culture ponds at the same time supporting the breeding of bait fish, but also supporting the breeding of bait fish in specialized bait fish ponds, regularly catching bait fish into the Mandarin fish culture ponds.

3. Water quality management

Chiniperca chuatsi fish culture on the water quality requirements, especially dissolved oxygen, a moment of negligence, can lead to total destruction. Dissolved oxygen in the water is more than 5 mg/L, which is favorable for the growth of Mandarin fish, and cannot be lower than 2 mg/L. Mandarin fish farmers in Dongtai, Jiangsu Province, have installed dissolved oxygen controllers in each pond, with a set value of 3.5 mg/L. Below this value, they will automatically activate the oxygenation equipment to increase oxygen in the whole pond. Pond ammonia, hydrogen sulfide, nitrite, pH value of the need for regular testing, regular use of biological agents for water quality control.
