I. Pond selection The ponds with cultured catfish tails should be constructed in places where the water source is sufficient and the drainage is convenient. Experience has shown that the normal growth requirements of the cell-tailed fishtail are 3 mg/L or more, good growth when the dissolved oxygen is more than 5 mg/L, and slow growth when the dissolved oxygen is less than 5 mg/L. Therefore, the inaccessible ponds need to be equipped with aerators, otherwise the fish should not be cultured. The bottom of the pond is better on the soil, and the water depth is 1.5-2.0m.
Second, prepare before restocking
1. Dredging and disinfecting old ponds must first drain the pond water and remove excess silt from the bottom of the pond out of the pond. Mu l00kg of quicklime, evacuated with bamboo gingiva, or disinfected with 30ppm bleach. Sterilize the sun tank for two weeks. During the drying season, the water intake and drainage gates should be well-maintained to facilitate water changes during the breeding period.
2. Feitang uses a 60-mesh sieve to make a conical mesh bag to infiltrate the water, so that the depth of the pool is 60cm, and 100kg of organic fertilizer or 2ppm of fertilizer (urea, etc.) is applied in the mu. Gradually add water to 1.5m. If large-sized fingerlings of 40g or more are to be released, they can also be fed directly to the pond after 1.5m, and the pH value of the pool water can be adjusted to 6.5-8.0 to release the fish species.
Third, seed stocking in order to shorten the breeding cycle, to achieve early stocking, the morning market, ponds single catfish tail {fish back} should be stocking 10-20cm of large-size species, generally 1,000-1500 tail stocking per acre. The selection of fish species requires uniform specifications and no injuries on the surface. Strong vitality. Fish seedlings were soaked in 5% salt water for 5-10 minutes before disinfection.
Fourth, feed feeding
1. The choice of feed and the amount of feed required for feeding are fresh and palatable. The protein content of feed is required to be 30%-35% in the initial stage of stocking, and the protein content in the middle and later stages of breeding can be reduced to 25%-28%. The conditions can be fed small fish, chilled fish, snails or snails, snails and snails must be cooked and chopped. The initial stage of feeding the fish is 3%-4% of the body weight of the fish, and the body weight of the fish is 2%-3% after reaching 500g.
2. Feeding method The channel catfish {fish back} likes low light feeding, so feeding time should be chosen at dawn and dusk. The punctate tail {fish return} has a clustering property, and it can be fed regularly at a fixed point to increase the feed utilization rate.
V. Routine management and disease prevention In order to avoid the formation of “bloom†due to over-fertilization in the later stage of cultivation, each pond should be stocked with 60 turtles and 40 turtles. When the fish has a body weight of 250g, micro-flowing water should pass through the pond from 9:00 pm to 4:00 am the next day. The pond with inconvenient water source should be started with an aerator to ensure the water-soluble oxygen content of the pond. Sprinkling quicklime regularly can not only regulate water quality, but also play a role in disinfection.
Pleurotus ostreatus has strong resistance to disease. As long as it manages water quality, it will not cause disease. During the middle and late breeding period, the bait is fed for 3-5 days every half a month. The bait uses allicin and Vc. Mixed feeding can not only enhance the disease resistance of the catfish tail, but also promote its growth.
6. The market price is the best when harvesting catfish tails and weighing 450-650g. When a weight of 450g can be gradually listed for sale. In general, it is used to pull nets to catch and catch large and small. Flat bottom ponds generally have a catch rate of over 70% on the first net, and up to 90% on the tallest ones. The feeding should be stopped 10 hours before catching.
Using the same raw material as above, adding seasoning liquid preparation process. There are two types of
Instant vegetable:such as seasoning surface anesthesia.seasoning JinPing.Sauce radish etc.
Kamameshi:Used to cook rice, that is cooked with rice at same time, making rice with taste and vegetables.
According to the different formulations, there are Maitake kamameshi, five mesh kamameshi, mountain vegetables mixed kamameshi, Castanea mollissima kamameshi etc..
Seasoned Vegetables, Instant Vegetables, Seasoned Boiled Vegetables
