The long-named (mztus elongtns) local horsetail bone is the main economic fish in rivers in South China. The fish is delicate and nutritious. Deeply loved by consumers. The market price is high, but due to overfishing in recent years and the depletion of resources, it is of great significance to carry out artificial breeding. I have cultivated it through several years and now summarize the technology as follows:
1. The pond has long conditions, likes good water source, fresh water, no pollution, convenient drainage and irrigation, quiet environment, no leakage, and the bottom sediment is made of sand and gravel as a good pond. The pond area is 1~3 mu and the water depth is 1.0~2.0 meters.
2. The second-instar fish stocking stocking specifications of 10 to 15 centimeters, the time in the 3 to 4 months of the year, stocking 1,000 to 2000 tails per acre, requiring size and size to be more tidy, strong in physique, no injuries, and no disease. Nesting 10 to 15 centimeters and 50 centipedes. Generally do not stock fish that have strong ability to catch food. The fish fry were cultured and before soaking for 10 minutes in a salt solution at a concentration of 10%.
3, feeding long? Is a river bottom carnivorous fish, mainly aquatic animal, mainly for artificial breeding of fish species 1 to 4 weeks after stocking, to long-term tame food, began to feed quail, fly maggot, etc. , and then gradually fed artificial ingredients, protein content of about 35% to 40%. Daily feeding 2 times, respectively, in the morning and evening. The daily feeding amount is 2% to 5% of the fish's body weight. Feeding should be based on the weather, water temperature, and the fish's feeding habits. You can always feed some snail meat, meat pulp, fly maggots, quail, etc. Supplement the nutrients needed for growth.
4, water quality management normal every 3 to 5 days? _ once the water, high water temperature, feeding more, poor water quality, flushing should be more, where the conditions for micro-fluidic aquaculture best, generally 10 to 15 days mu 20 kg of lime or water and prevent fish disease.
5 Day-to-day management Every morning and evening, we inspect the pond one by one, check the water level, water quality, the eating and drinking activities of the fish, and remove the sundries in the water. During the rainy season, we must do a good job of flood prevention and escape prevention. If you are afraid, you should try to calm the environment. .
