Long kiss, also known as Jiang Tuan, back to the fish, the meat is delicate, is the same as the river, the swordfish, is one of the rare fish species in the Yangtze River, the market demand is strong, the price is stable. This unit has been engaged in the research work of the fish since 1996. At present, it has mastered the complete sets of techniques for seed breeding and adult fish breeding. Artificially cultivated seedlings are very suitable for water culture in ponds, lake cages, etc., and are currently used for aquaculture. Hot varieties. 1. Breeding conditions: Ponds, 5-10 acres in area, water depth 1.5 meters or more, good water source, convenience for water ingress and egress; lakes, river beach cages; 5-20 square meters/piece. The size of the mesh depends on the size of the fish, so that water exchange can be smooth. 2, seed stocking; spring stocking more than 20CM one-year-old fish species, require specifications and neat without injuries, ponds stocking about 500 per acre, cages 10-30 stocking per square meter, can be specifically based on the actual situation of stocking. Lakes, reservoirs, and riverside areas can give full play to the advantages of good water quality and high market prices. The combination of holding and stocking is a better prospect. 3, daily management: feed using self-made feed (protein content of more than 38%) or animal slaughtered leftovers, chilled. The food bowl was used for feeding, and about 3 food bowls were placed per acre, twice a day, and the feeding amount was adjusted according to the food and weather conditions. Change the water by 20% every week to keep the water quality clear. In summer, high temperatures should deepen the water level and reduce the pool water temperature. Oxygen generators are opened depending on the weather to prevent oxygen deprivation. At that time, the general meat multiplier was around 10, and the survival rate was over 90%. The direct cost (excluding the rented labor) was about 7 yuan/kg. 4. Disease prevention and control: In the process of breeding, the common disease is parasites, especially in the case of poor water quality. The prevention and control method is to maintain good water quality and use 0.3PPM trichlorfon once a month for prevention.
