Artificial breeding of bamboo shoot fish
Bamboo shell fish school name Jianbantangtang, due to its shape like bamboo shoots, so named shellfish. The fish is native to Southeast Asia. The largest individual can reach 5 to 6 kilograms. The meat is tender and delicious. It is a rare freshwater fish species. The bamboo shellfish live in the bottom layer of mud and grass with micro-flowing water, hi caves, sexual humility, poor jump, low oxygen tolerance; optimum temperature 15°C to 35°C, optimal temperature 25°C to 30°C, and death below 10°C Can grow in acid water with pH 5 and salt water with 1% salinity. Juveniles use microorganisms in the water as bait, and adults can eat small fish and shrimps, and have a strong ability to fight hunger. Artificial breeding can feed mixed fish and synthetic feed. I. Pond conditions The pond area is suitable for 0.15-0.4 hectares, water depth is more than 1.5 meters, there is less silt, there are water exchange conditions, and the water quality is good. The water surface can be properly stocked with narcissus or duckweed, and a "fish house" made of cylinders, old tires and Other objects can be placed at the bottom of the pond. Second, seedling seedlings are mostly introduced from Southeast Asian countries. The fish should be released when the weather is stable and the water temperature is above 20°C. Put 2,000 to 3,000 tails per mu. Apply 10 μg of potassium permanganate solution for 10 minutes before inoculation to sterilize and prevent disease. The fry are first kept in a corner of the pond for 2 to 3 weeks with a dense net, and later spread to the big pond. Third, the shellfish were fed as carnivorous fish. Zooplankton, such as rotifers and Cladocera, were fed at the seedling stage. After 2 cm in length, fish and shrimp seedlings and small insects were preyed on. Therefore, artificial ponds should be cultivated with a certain amount of zooplankton, and some fish flowers should be given appropriately. After the fish species have entered the pond, they can continue to feed fry (shrimp) of appropriate size, and they can also take chilled and mixed fish in the coarse stage of the fish until they are cultivated. The daily feeding amount is about 3% of the fish's weight, so the feeding amount is 1/3 for breakfast and 2/3 for dinner. Fourth, water quality management and sub-tank breeding shellfish fish resistance to hypoxia, the current yield of hundreds of kilograms per mu does not have to use aerator, the water to partial fertilizer, green cool as well, the pH value of 7 or more. After the rearing period, appropriate amount of water can be changed or every month, 5 to 10 kg/667 square meters of quicklime can be poured. After the fry period, polyculture of 20 to 30 flowers per mu and 30 fishes will help to adjust the water quality.
