First, cage production
The cage material was made of polyethylene knotless mesh and made into rectangular or square culture cages.
The turtle cage has an area of ​​20-50 square meters and a height of 2 meters. The net surface is covered. Raft cages are available in sizes of 3m 2m 1m or 10m 3m 1.5m and a 6 cm wide raft extends around the top of the cage. The beard-fishing net cage uses a closed cage with a mesh size of 1.3 cm and has a size of 742 meters or 552 meters. This type of cage can be used to raise the adult bream into 0.5 kg to 2 kg of adult fish.
Second, the cage settings
Choose waters that are sheltered from the sun, have a quiet environment, are fresh in water, free from pollutants, have no obstacles, have good sunshine conditions, have a depth of 3 to 6 meters per year, and have a dissolved oxygen level of 4 mg/l or more. The cage is about 4% of the water surface of the set water. The cages are placed into the water 5 days to 7 days before the seedlings are placed in the box. The wooden posts or cement columns are erected in the four corners of the cage. The net is fixed and the pendant is fixed around the bottom of the net to prevent water flow or wind from tilting the cage. . The bait station is located in the center of the cage, and is fixed in a box at a distance of 20 cm below the water. The food platform is 10 cm high and the square frame is 40 cm to 50 cm long. The bottom of the frame is surrounded by screen cloth. One food table per box.
The bottom of the cage is immersed in water 0.4 to 0.8 meters. After raising cages to be fixed in the cages, the cages will be filled with water and peanuts will be placed in one-third of the cage area. Raising cages need to be considered for heavier turtles. A 4 cm diameter bamboo pole can be bundled between the wires and the cage is 30 cm above the water surface.
Third, seed stocking
Seedlings should be tested for water 10 to 15 days before stocking. Seedlings are required to have complete body surface, no disease, no injuries, strong physique, and neat specifications. When entering the box, first wash the seedlings with 4% saline for 5 minutes to 10 minutes.
Turtle stocked per square metre: 120 young turtles or 60 to 80 turtles or 20 to 40 adult turtles.放 Stocking per square metre: 50 grams/tail, 160 tails; 25 grams/tail, 250 tails or 15 grams/tail, 450 tails to 500 tails. The breeding time was from May to July. After 10 days of domestication, 7 to 17 tails of loach were placed on each square meter of cage, and a small amount of carp was stocked. Bearded quail stocking per square meter: body length 8 cm to 10 cm 70 to 80, requiring a one-time foot. Restocking time is appropriate in late May.
Fourth, feed the bait
Feeding should be done in a regular, fixed, qualitative, and quantitative manner to ensure that the cultured species in the box are well fed and fast growing.
Turtles are preferably buoyant particles, and they can also be fed by blending in powders. Generally about 1.5 kg dry material per 50 kg per day, each feeding amount to finish within 2 hours. The squid is mainly fed with animal fish such as wild fish, cockroach and fly maggots. It feeds 3 times a day at 9:00 a.m., 2 p.m. and 6 p.m., and the feeding ratio is 3:2:5. The feeding amount is 5% to 10% of the total weight of the alfalfa. The beard carp was stocked for 15 days to 20 days, and was mainly fed with animal feed such as cocoons, fish meal, snails, cockroaches, fly pupae, livestock and poultry organs and blood, and was injected 4 times to 5 times per day. Take half an hour before eating. Later, as the fish grows up, it can feed pellets with a diameter of 2 mm to 3 mm and feed it twice a day, ie 10 a.m. and 5 p.m., and the daily feeding amount is 5% of the total fish body weight. ~8%.
V. Disease Prevention
Disease prevention and control should adhere to the principle of "prevention-based prevention and control integration", that is, the combination of immersion in the net, drug hanging bags, and drug treatment.
Turtles can be regularly sterilized. Normally, 20 grams of bleaching powder is used per square meter of water body. The nursery turtles should use metal nets to prevent damage to water mice and mink. During the growing season, squid is hung with bleaching powder once every 10 days to 15 days, and is fed with 0.5% oxytetracycline on a regular basis. The bottom of the net is cleared once every half a month, and water is disinfected with quick lime and strong chlorine. . Pay attention to rodent damage. In the process of keeping the beard owl, after entering the month of June, it shall be disinfected once every 10 days to 15 days. Every 667 square meters shall be sprayed with 0.75 kg of bleaching powder or 12 kg to 15 kg of lime.
Sixth, daily management
Adhere to the morning, mid-night and night-time inspections of the custody box to observe fish conditions, water conditions, and cage conditions. Clean cages timely to prevent damage to cages, escape of cultured species, and clogging of cages. In particular, immediately after the flood, clean them immediately to remove debris and excess algae. Keep the exchange of water inside and outside the cage open. Pay attention to changes in water quality and adjust in time. The cage location creates a good living environment for the fish school.
Turtles and cockroaches need to be screened and classified in time to adjust their density as the fish grows. The beard carp is best taken in batches and can be harvested from the beginning of September at any time to catch fish weighing 0.5 kg or more.
