2, clear pond disinfection. Fish ponds were drained in front of the pond and the pond was drained. Excessive silt was excavated, and the bottom of the pool was exposed for 20 days. Then the water was poured in 10 cm. The whole pool was sprinkled and disinfected with 75-100 kg of lime slurry per acre. 3, fertilizer bait. Ten days before stocking, the fry was filtered and injected to a depth of 0.6-1 m. Each mu was used to ferment 100-500 kg of organic fertilizer (depending on pond bottom quality), to cultivate natural plankton in the pond. 4, fry stocking. After fry hatching, 3-4 days after hatching, the fry grows to a length of 4-5 cm in body length. This method can be similar to that of “Four Home Fish†seedlings, with 3-5 thousand tails per acre, 20-30. Divide the pond after the day and switch to the breeding stage. It is cultivated from summer flowers into large-sized fish species with a tail weight of about 50 grams, with 8000-9000 tails of summer flowers per acre, and 600-700 tails of squid with a length of 6-10 cm. 5, feed feeding. The fish fry in the bottom of the pond was not fed feed for 4 days, and the zooplankton in the pond was fed. When the fry body reached 4.5 cm in length, the compound feed was started. When feeding, first tame the food by stirring the pool water at the feeding site to send a sound to stimulate the fish species, then sprinkle a small amount of feed, and so on, repeat every 10 seconds, each time Eating 10-20 minutes, 4-7 days can make the fish form the habit of eating groups. The content of protein in the compound feed is about 40%, which is fed twice a day, and the feeding rate is 3-5%. 6, daily management. Keep the dissolved oxygen content in the pool water above 3 mg/l, pH 6.5-8.3. During the feeding period, fresh water is changed every 7-10 days. The depth of water increases with the increase of the fish body and gradually increases to about 1.5 meters. Each cubic meter of water is regularly splashed with 0.5 g of chlorine dioxide to the whole pool. Prevent fish diseases and regulate water quality.

Prongtail fish breeding techniques
1. Pond conditions. Seed pool requirements close to the water, good water quality, easy access to the water, the bottom of the pool is flat, less silt, pool sturdy not leaking. The summer flower cultivation pond area is suitable for about 1 mu, and the species breeding pond area is generally 3-5 mu and the water depth is 1.3-1.6 meters. Each tank is equipped with 1.5 kilowatts or 2.5 kilowatts of aerators and is equipped with a pump.
