(1) Fry cultivation. Fry cultivation generally takes 25 to 30 days. It can be cultivated in running cement ponds or general ponds. The former is generally used in small-scale production, while the latter is suitable for large-scale production. The cultivation method refers to pond fish farming.
(2) Fish breeding. The fish pond area ranges from 3/15 hectares to 5/15 hectares and the water depth is 1.3 to 1.5 meters. One week before stocking, clear the pond and disinfect it. Restocking time is generally from July to August. There are two kinds of stocking methods, namely single-cultivation and polyculture with cockroaches and squid species. Mixed breeding is better, and cockroaches and squid can play a role in controlling water quality. Stocking densities should be determined based on expected discharge specifications and pond conditions. - Generally, 5,000 to 7,000 summer flowers are stocked on l/15 hectares, together with 500 to 1000 tails of summer and summer flowers of similar specifications. During the rearing of the fingerlings, the artificial feed is mainly fed, and the crude protein content of the feed should reach 35%. Feeding amount is generally 3% to 5% of the total weight of the fish, and it is fed once every afternoon. To do daily management work, keep the pool of dissolved oxygen above 3 mg/l.
