Whale 鲶 Artificial breeding technique [Squid]
1, fry cultivation 1 pond conditions and preparation to choose the area of ​​1 to 5 acres is appropriate, the pool depth of 1.5m above, no weeds in the pool, flat pool bottom, non-leakage pond as a fry cultivation pool. 10 days before entering the pond, the fry is sterilized by the dry clear pond, with 75 to 100 kg of lime or 5 to 10 kg of bleaching powder per mu. After 2 days of disinfection, the water injection was 0.6 to 0.8m deep. Five to seven days before the fry enters the pond, 500 kg of chicken manure is fermented and fermented per mu, and zooplankton such as rotifers and cladocera are cultivated. When manure is applied, quicklime should be mixed in. To speed up the fermentation of chicken manure, chicken manure can be collected and sealed with plastic cloth. 2 Fish fry stocking 3 to 50,000 tails per mu of stocking herring. Choose sunny, windless or breezy weather to put the seedlings. Before the fish are put into the pond, they are first put into cages and sieved to make them or trussed. The cage uses iron bars as a frame. Put the nylon bag or other container that holds the seedlings on the surface of the fish pond first. When the water temperature in the bag or other container is the same as the water temperature of the pool water, put the fry in the cage or tie box. After fishing for 2 to 3 hours, the fry is fed and the fry is placed in the pool. Before laying the seedlings, arrange shading objects, such as water grass, straw curtains, palm husks, etc. in the shallow waters on the shore of the pond to provide concealed items for the fry, and the fish fry under the cover. 3 Feeding and management of fish seedlings Three days before entering the pond, zooplankton cultured in the pond can feed on feed instead of feed. If ponds have a small amount of zooplankton, they can be fed from other ponds. The fourth day can be fed with leeches and fish gills. Quanchiposa can be used. The amount of water fed is 5 to 10 kg per acre of water. According to the feeding conditions of the fry, the amount of feeding can be controlled flexibly. 4 After the fry is out of the pond and cultivated for 7 to 10 days, when the total length of the fry reaches 3 to 5 cm, the pond should be subdivided in time to enter the next stage of feeding. 5 fish disease prevention and control phase of fry breeding inclined to tuber disease, there are two treatment methods: one is Quanchiposa copper sulfate and ferrous sulfate mixture, copper sulfate 0.5g per cubic meter of water, ferrous sulfate 0 .2g; Second, Quanchiposa formalin, with 100 grams of formalin per cubic meter of water. 2. Adult fish farming The breeding of white-headed turtles can adopt three methods: medium and large water surface breeding, pond nest raising, and pond main breeding. 1 The waters of large and medium-sized lakes multiply in lakes and reservoirs. Usually, small-scale, low-value miscellaneous wild fishes such as head fishes and squid fishes are rich in resources. These small-scale, low-value wild fishes are a good feed for pregnant women. Through the stocking of fish heads, small, low-value wild fishes in lakes and reservoirs can be transformed into high-value head lice and raise the breeding efficiency. From late June to early July, 5 to 10 tails of summer flowers with a size of 3 to 5cm per acre of water are stocked, and 4kg to 7kg of tails can be produced per acre in the fall. Through stocking and breeding, 50 to 100 yuan per mu of water can be increased. It is advisable that fisheries in large and medium-sized waters be stocked with special precautions, and it is advisable for the fishery professionals to fully demonstrate that blindly launching fish that harms the main cultured fish or fish with high economic value will result in losses. 2 ponds raise the pond to raise the white-headed turtle should choose small wild fish rich adult pond or broodstock pool nest, do not nest in the breeder pond, otherwise the pregnant fish will eat fish, resulting in losses. From late June to early July, the body length of 3 to 5 cm in each acre will carry between 10 to 20 tails, and it will be possible to produce about 100 kg of 750 to 1500 g of tails in the fall, and an increase of 100 yuan per mu. 3 The pond raises a pond. The pond area is a few hundred square meters to several tens of acres. The bottom of the pond is flat and does not leak water. One week before the fish was introduced into the pond, dry ponds were used to disinfect the plants. Each well had 75 to 100 kg of lime or 5 to 10 kg of bleaching powder. Each manure uses 100 ~ 200kg of manure. 2 The stockings of the fish are stocked with summer flowers and one-year-old fish. In the summer of stocking, at the beginning of May, 80 to 100 tailed squid spring fishes weighing 100 to 200 g per acre are stocked, and the ratio between squid is 2:1 to 3:1. In late June to 7 At the beginning of the month, 150 to 500 tailed bream species with a body length of 3 to 5 cm per acre are released. The stocking bream species required to be tidy so as not to kill each other. Until the fall of the pool, the size of the tail of the tail can reach 750 ~ 1500g. The survival rate of pregnant women is generally about 60%. Stocking first-year fish species: In recent years, the large-scale Wycomelian clams have been welcomed by the market. The market price per kilogram reaches 22 to 26 yuan per mu, and the stocking size is about 1kg. There are about 20 to 30 tailed sturgeon species, and the stocking specifications should be neat. In addition, 30 to 40 tails of squid species with a stocking size of 1 to 1.5 kg are used. To fall out of the pond, the yield per mu can be reached 75 to 100kg in the face of the crop, and the average size can reach about 4kg. The survival rate of pregnant women can generally reach 80% to 90%. 3 feed feed can feed wild fish, fish fry, fresh frozen sea miscellaneous fish and other low-value fish, chicken intestine and pig lung can also be fed, etc., feed by electric mincer after mincing and feeding. Place a 3 to 4 square meter bait station in the pond. It is also possible to feed directly without bait stations. In June and September, feed once a day and feed it once in the evening. The daily feed amount accounts for 2% to 5% of the total fish weight. From July to August, feed 2 times a day, feed once in the morning and evening, feed less in the morning, and feed more in the evening. The daily feeding amount accounts for 5% to 15% of the total fish weight. The feed is minced and placed on a bait station to feed the fish. It is advisable to feed the fish every 2 hours or so. 4 Water quality adjustment During feeding, ground water to maintain a water depth of about 1.5 meters deep. From July to August, lime water is splashed every 15 to 20 days, and 20 to 25 kg of lime are used per acre of water. 5 fish disease prevention before the fish into the pool, the need for fish disinfection, 3% saline can be used to dip fish, the time is 5 to 10 minutes. The feed to be fed is fresh and should not be fed to spoilage feeds. Feeding once every 20 days alligin medicine baits, add 50 ~ 100g per 100 kg of feed, can also be fed to other antimicrobial baits.
