Wuhan Yinfeng Modern Aquaculture Development Co., Ltd. Tip: reasonable scientific farming techniques ..

 Wuhan Yinfeng Modern Aquaculture Development Co., Ltd. in 2011 assumed the "Procambarus shrimp breeding and efficient eco standardized breeding technology demonstration" project, after nearly two years of intense implementation, the establishment of a standardized seed breeding freshwater crayfish demonstration base 100 acres, more than 100,000 fingerlings per mu, Mu Xiaoyi up to 4050 yuan. The establishment of a freshwater crayfish efficient ecological farming demonstration base 900 acres, the per mu yield of 200 kg, Mu Xiaoyi up to 3120 yuan. Promote freshwater crayfish efficient ecological aquaculture area of ??10,000 acres, more than 1,500 kg per mu, mu benefit more than 20,000 yuan. Now farming techniques are summarized as follows: scientific and rational site selection requirements Xiatangkou near water, fresh water pollution, to facilitate the entry of drainage, soil with clay as well, good water retention properties. Fangtao facilities must complete escape crayfish have against the current habits, the fence around the pond Fangtao facilities should be set up, at the same time into the outlet is to do Fangtao work and regular checks. Reasonable put shrimp species stocking critical success put seed breeding success equal to the entire half. Should be selected disease no injury, complete appendages, bright in color and consistent standard of lobster seed, Quality put 200 acres of juveniles / kg of 50 kg. If there is no principle of proximity bred seed acquisitions should be used. During transport can not squeeze, dehydration, multiple multi-point delivery, to ensure the survival rate of fry stocking. Raising good plants "To keep a good shrimp, must be grown plants", a good ecological environment, rich in aquatic resources is the key to success in breeding. Crayfish feed both plants is its habitat shelling places. Aquatic species to be more, not only have submerged plants, but also have floating plants, but also emergent plants such as water hyacinth, Elodea, Hydrilla, wild rice and so on. Plants planting area accounts for 60% to 70% of the total area of ??the pond. Reasonable feeding practices in farming in order to obtain greater profit margins, the vast majority of farmers have increased the fine material inputs. But also they misunderstand, often focus only on the fine material feeding, ignoring the green fodder inputs, pay attention to meat and vegetables. It found that the proportion of food in the grass crayfish account for more than 80%. Practice shows that the lack of resources in the case of grass lobster produced low yields, poor quality, difficult to sell a good price. At present, "steel shrimp" "shrimp steel" appeared in large numbers is a major cause for lack of grass. Concentrate more bidders and a lack of grass, not only will the lack of eating delicious crayfish feed, and make crayfish lack of suitable habitat for life shelling places, resulting in reduced number of shelling, even shelling, resulting in cessation of growth , and mature crawfish season has come to form the individual is small but has red shrimp hardened phenomenon. Therefore, the breeding process to increase investment in green fodder is particularly important. Daily ration generally fodder storage pond shrimp 6% by weight of the can. Molting hormone added 1 ‰ daily ration should add the total amount of concentrate, and regular use. In addition to daily adhere to scientific management "Three Views five ground", but also to strengthen the biological predators and Drug Administration clearance. Clear pond in the transformation of disinfection should be thorough, resolutely eliminate snakehead, eels and other fish Meng fierce, always pay promptly expel rats, waterfowl and other biological predators. Crayfish less disease, generally not the disease, if the incidence should remedy, sterilizing it with chlorine dioxide. Ciliates on the use of zinc sulfate, disable polyesters, organic phosphorus-based drugs. Adhere to application of lime once per month, the amount of 20 kg per mu, can improve water quality, but also increase water calcium and promote lobster shelling. Water management according to seasonal temperature changes and press the "shallow - deep - shallow - deep" principles of management. "Agriculture on the 10th," freshwater crayfish species introduced from Australia monomer weight of 300 grams or more of Australian freshwater crayfish males parent of the use of the central region of Klinefelter crayfish stock Yinfeng Wuhan Modern Aquaculture Development Co., Ltd. 93 grams more females as a female, were repeated mating, through foster care, parental purification, rejuvenation, choose Excellence program, a new generation of cultivated varieties, agricultural Wuhan Yinfeng Modern Aquaculture Development Co. No. 10 "Freshwater lobster species compared with wild lobster and other species, it has the following advantages: (1) head hypertrophy (about 220 grams of monomer), plump belly meat, meat and more fresh and delicate fecundity: perennial spawning (egg load is wild Lobster 2-3 times) (2) fast growth, high yield: 3-4 months spawning can be listed, single weight up to about 50 g, 120 pounds per acre seed delivery, can produce commodity shrimp 3000 . pounds or so (3) omnivorous easy to manage: all kinds of plants, leaves of grass, residue, rice bran, wheat bran, animal waste, residual soup leftovers hotel so easy to manage, a person may raise 30-50 mu (4. ) adaptable aquaculture simple: "Agricultural 10" freshwater lobster strong survive, in all our waters are breeding ponds, paddy fields, lakes, braided river, wild lands (have water conditions), the marshes are breeding (5) reproduction less stable disease: farmers once voted species benefit for many years, "Agriculture on the 10th," after freshwater lobster vote, at least within five years, no longer need to put in seed, bred juveniles can continue. As a seed spawning, and less disease, multiply stable Tel: 027-65608881 Address: Jianghan District Development Road No. 166 Jiang Feng, Room 902, Building A, Wuhan Yinfeng Modern Aquaculture Development Co., Ltd. official website: www.Lx1818 a situation .com
