1. Pond conditions: the area of the bass culture pond is 5- 10 mu, the water depth is more than 2 meters, the water quality is pollution-free, the water source is sufficient, the water supply and drainage facilities are good, and the transportation is convenient. At the same time, 1-2 1.5 kW aerators and standby generator sets are required.

2. Cleaning and disinfection of pond: Before perch stocking, it is necessary to clean the pond, using 7- 10 kg of quicklime per mu, keeping the pool water at 10-20 cm, dipping in wine and splashing wine, adding water to the depth of 1 m after 7 days, and applying 0.75kg/ mu of diamide at one time. After two days, the pond water turns oily green and can be stocked.

3. Temporary culture method: At present, most of the perch fry are caught in the sea, and the fish fry in the sea in spring is about 2.5-4 cm. After fishing and transshipment, fish will be hurt to varying degrees. In order to improve the survival rate of culture, it is convenient to carry out intermediate temporary culture first, and a 40-mesh cage is set in the culture pond.

4. fry stocking: perch is temporarily raised, with 2000-3000 perches per cubic meter of water, disinfected with chloramphenicol, fed with Artemia larvae 10 days before, and then fed with fresh fish food. When the fry are cultivated to about 10 cm, they are put into the cultivation pond for cultivation according to the ratio of 1.5 fish per square meter.

5. Bait selection: The bait of perch is mainly low-quality miscellaneous fish, supplemented by artificial ingredients. It is very important to feed regularly and quantitatively because of the large appetite and fast food grabbing. When throwing bait, you should master the degree, let the fish eat enough and don't waste the bait.
