Fisheries Phone: 0394-6639132 Mobile: 13461328846 fry foster a pond preparation: Choose 1-2 acres, depth of 0.8-1.2 meters, less mud, something the pond, according to conventional methods clearing, disinfection 2 fertilization (also known under fertilizer. Tong): 7-10 days before the fish pond can be fermented manure was applied, such as pigs and cattle dung 150-300kg / mu (about 5 percent), can also be applied to 5-10kg / acre of inorganic fertilizer (fertilizer, phosphate, etc.), lime disinfection at the same time (the amount of 150kg / acre), a week after the fish pond is just under the peak of rotifers, fry palatable enough food, robust growth. 3 Fangmiao: to put the fish first with front put dense mesh pull the empty net addition to the wild hybrid, but also put a cheap flower silver carp fingerlings 50-80 tailed test the water, to prove everything safe fish, 10-25 ten thousand / acre. 4 fresh water pond: no Fertilizers, fry directly into this method because of the water rotifer less palatable food, enough to eat, so frail fry survival rate is low. 5 Management: (1) timely feeding: fish into the pool after, the first few days grow particularly fast, often have insufficient natural food, so pay attention to feeding. Add cooked chicken egg yolk beaten commonly soybeans spilled feeding. Soybeans per acre per day plus 3-5 2-4kg cooked yolk spill immediately fed into a thick, focusing fed pool near the water a few meters. Also poured fresh pig's blood once every three days, filtered. Milk can be directly eaten some of the seed, you can also fertilize the water, abundant natural food. Currently, the market is also expected circulation fry, the shape of the microcapsules or powder, can be fed from a 6-8 start, can make food, but also to lure fish snatch, so as to promote the development of the digestive tract, help to improve the survival rate and seedlings. (2) fertilizer and water management: fertilizer applied once every three days, so that the water rotifer remain at a high level. Every day can be pumped into the pond from the fatter part of the water added to the pool both for the fish fry to increase natural food, but also to prevent adding machine well water caused by excessive air bubbles disease. Week should change the water 1 / 3-1 / 2. (3) carefully observed: fish cultivation process should step up inspections. View their activities, feeding, growth, changes in water quality, with or without predators, disease and so on. Meanwhile fry timely response sub-pool, prevent too close cause uneven specification. If necessary, the need to pull the net exercise fry enhance endurance. Second, the specification by the fingerling rearing fry cultivation, fish body length and weight were up many times, but also enhance the ability to adapt to many, diet change already has a variety of features, like fine starting material, it should be a smooth transition as soon as possible to eat feed . Feeding methods are: 1 monoculture method: choose 2-4 acres, depth 1-1.5 acres, sterilized and Pond, put fish fry 3000-6000 / acre, fed with feed or soybean meal, chrysalis, fish meal mixture requiring more than 35% protein feed 8-12 times a day, feeding rate 5-8%. 2 polyculture method: fry carp polyculture with other species, mainly carp may or supplement. In terms of carp mainly feed ration should be strengthened, if the flowers mainly carp may be appropriate to foster quality, if the grass-based, the carp should put less. 3 feeding and management (1) open as early as opening sooner eat fry growth starting sooner, the better the growth. We should seek as soon as possible a smooth transition to the full price of feed fed. (2) pay close attention to the early wang food species (Ortega is 25-30 inch piece into the time) grow particularly fast, the body length were fast weight gain, feed the need is greater, you should strengthen feeding, some fishermen This feeding rate of more than 10%. (3) feeding adhere to qualitative, timing, positioning and quantitative "; four";, to be fed by fish feeding rhythm. (4) good daily management of early, middle and late "; three patrol four examinations"; grasp climate, fish love, illness, keep the fish grow fast, but also regularly check water and flood control, Fangtao work.
