Black fish set white pheasant technology
Black fish set flower white lotus technology I. Tongkou clearing and disinfection Blackfish cover flowering Baijitang mouth area to 6 ~ 8 acres is appropriate, the area is too small, the water quality is easily deteriorating, in summer, the main high-temperature Venezuela easy to induce disease, area Too big, high investment in production, and inconvenience in management. The fish ponds are 2 meters deep, and they leave no or less silt on the bottom of the pond. Weeds should be cleared of weeds in the Western Zhou Dynasty, and ponds in ponds should be reinforced to prevent seepage and water leakage. Thoroughly clear the pond with lime during the 20 days before stocking, and use 100-150 kg per mu. After 10 days, bleaching powder (30% of available chlorine content) is used for clearing the pond once again. The dosage per acre is 5-7 kg, which can be entered after one week. Water fish species. 2. Feeding of fish species 1. Black fish species: The blackfish species should be stocked in early October. After entering the pond, the fish species can be fed to restore constitution and increase the survival rate of wintering. The fish species at the other side can take a restorative constitution and increase the survival rate of wintering. The fish species can be stocked every other year from March to April. Before the next pool must be strictly disinfected and prevented, generally 3% to 5% salt water soaked for 10 to 15 minutes after the stocking into the pool. The stocking specifications are best to be locally produced fish species in order to avoid long-distance transport causing fish injuries, affecting the survival rate, and avoiding the introduction of pathogenic bacteria from the outside. 2. Flower and white fish species: Fish and white fish species can be stocked before and after the Spring Festival. It is best to put them into the pool before the Spring Festival. Generally, the main black-fish pond has 200-250 tails per acre with flowers. For oysters and breams, 60 to 80 tails, flowers and white horns are sized at 6-8 tails per kilogram, and cockroaches and squid are sized at 10-15 tails per kilogram. Before the fishes are pooled, they must be sterilized and put into the pool. Third, feeding and management 1, feeding: to adhere to the "four set." The size of a pond can be set to 1 or 2 food places, and the black fish can be concentrated around the food field. This can create a situation of grab food, increase food intake, and reduce food waste. The type of feed is mainly small freshwater miscellaneous fish, supplemented by small marine miscellaneous fish, and the feeding amount of bait fish in the high season is 6%~8% of the fish weight. Wash the fish before feeding and feed the frozen sea fish. After dissolving, use a 3% to 5% solution of chyme to sterilize for 20 minutes. The feeding method is effective for gradual feeding, and most of the fish eat. After saturating, you can stop feeding. Flowers, white fleas, and squid are no longer needed for feeding. 2. Xuntang: It is mainly to observe the fish’s feeding, activities, incidence trends, and environmental changes twice a day, morning and evening. Regularly remove residual baits, remove excess aquatic plants from the pond, prevent fish from being caught, and have a floating image. Start the aerator. 3, water quality management: high temperature season. Black fish have large food intake, large metabolism, water quality is easy to produce black and odor, resulting in water body malignancy, is not conducive to the growth and development of blackfish, so the high temperature season generally 3 days a small change, 7 days a big change, where the conditions can be micro Water aquaculture, aquaculture water level to maintain about 2 meters, other time to see the change in water quality situation r to change the water, generally change the water every week 1/3, 10 to 15 days big change once, boring to watch the hot weather to pay special attention to promptly change the water or Add new water.
