If the fish ponds are usually fed with feed, aerator and good drainage and irrigation facilities, the stocking quantity can be appropriately increased. By desalination of domesticated fry, the survival rate can reach 80% Mak 95%. The fish can grow to 500-750 grams a year, with an output of more than 150 kg per mu and a market price of 16-20 yuan per kilogram.
