水泥池黄鳝养殖技术（Technique of eel farming in cement pond）

1、水泥池黄鳝养殖技术（Technique of eel farming in cement pond）Eel cultivation technique of cement pool is a safe and reliable, and the stable steady culture mode, which will cement pond eel breeding techniques are described below:1., select appropriate range of aquatic animals, eel farming in the cement pond, m

2、ore diseases, technical requirements are very strict. Therefore, before breeding, the environment should be improved and utilized, such as aquatic animals and plants, disease control and so on. The specific measures are as follows: (1) shift cut Alternanthera philoxeroides, Polygonum hydropiper and

3、other aquatic plants in the eel pool center shift cut area accounts for the whole pool of 2/3, more than 1/3 around the stage area, stocking of spirodelapolyrrhiza; (2) every 10 meters in 2 area, stocking 24 old turtle 1, loach 9 young. Lobster (Procambarus shrimp seedlings) 12.2. grasp the stocking

4、 density of cement pond eel is a kind of high density ponds, per square meter on the specifications for the 40 grams of eels from 2 to 2.5 kg; 60 grams of eels from 2.5 to 3 kg. Size eel to sub pool feeding. For individuals weighing more than 75 grams of eel, it should not be fed.3. to strengthen th

5、e management of public management is to strengthen the cement pond to reduce the incidence of eel, improve the yield of the key. In general, good management of cement eel breeding pond, stable length of 2 3 times; the mismanagement of the cement eel breeding pond, almost not long, or long 10.5 times

6、. There are six points in the management of cement pond:(1) the management of cement water irrigation should be eel tank of about 20 cm, when the summer heat, the water level rise to 30 cm. When the weather is cool, change water 35 days; when the weather is hot, change water 12 days. In order to kee

7、p the water fresh and soft, we can use the exuberant metabolism of the purple duckweed to purify the water. Not only every two days will be in the pool around 1/3 stocking of spirodelapolyrrhiza, with net salvage part, which is not close to dilute the vigorous growth, to absorb water and fertilizer,

8、 to keep the water clean.(2) every summer to shading measures, the temperature reached 25 degrees above, because the cement wall around the endothermic and exothermic pool temperature rise, resulting in the eel in nature water temperature at the same time, it is necessary to take measures to prevent

9、 heatstroke. A variety of methods in the eel pool cover, side frame to cultivate loofah, loofah vine grilled climbed above pond shading; can also use bamboo scaffolding shade curtain. No matter what kind of shading method is adopted, half Yin and yang are required to be covered. Once the cold days,

10、will open shade facilities, increase the eel pool of sunshine.(3) against the escape from late June to early July, frequent rainstorms, eel pool water level Meng Zhang, there should be timely drainage. In the night of rainstorm, eel likes to build a corner and cooperate with each other to flee. At t

11、his point, the night patrol should be done, and in the four corners of the pool to put a wider board, just in case.(4) feeding and management, generally speaking, Huang Shanri intake of food for the weight of 6% 8%. In order to eel fast growth, except for the Japanese eel meal let outside, must also

12、 do a good job eat non animal feed work, the animal food and animal feed fed alternately, in order to increase the comprehensive nutrition of rice field eel. Some eel likes to eat food, such as earthworms, small fish, shrimp and so on, a feeding can not be too much, otherwise the eel will be fed and

13、 died.(5) cleaning work of cement eel breeding pond, remnant food often have eaten, this is because the wind and rain, mechanical vibration and some dead eel stink caused by the impact, should promptly remove the remnant food and dead eel stink, and to determine the disease according to the dead eel

14、, according to cannibalism to determine the feeding amount.(6) regular disinfection and pest control, cement eel breeding pond should be especially well regular disinfection and pest control work regularly. Every 15 days should bleach 25 mg / kg of lime or 1 mg / kg of the total pool disinfection on

15、ce per month; with 0.7 mg / kg 90% crystal trichlorfon a pest. In addition, often feeding earthworms and meat of the eel pool, monthly Abendazole 2 grams, mixed with fresh 4 kg, 50 kg of feed eel 2 times.4. disease prevention and control of cement eel breeding pond is a pond all the eel breeding pon

16、d most susceptible disease. In the prevention and treatment of diseases, we must adhere to the principle of combining prevention with prevention and control. Cement eel pool area is small, easy to manage. Therefore,Being ill is easy to spot. Once the disease is found, it should be timely remedy. Tre

17、atment, it is best to use in, West, the three combination of methods for treatment.The most likely occurrence of eel fever, skin rot and coma in the cement pond. Whether it is that disease, should refer to the text after the disease prevention and treatment program in a timely manner for treatment.5

18、. overwintering management, cement pond eel farming, generally use waterless winter. In early November, when the temperature dropped to 810 degrees below, slowly draining water, let the eel into the sting; when the temperature drops below 5 degrees centigrade, in the pool on the inner layer about 51

19、0 cm thick fresh straw, let winter eel. Frozen in time, dont let the bottom of the pool with waterlogging, to prevent freezing test eel suffocation.Technique of eel farming in cement pond? I have a 120 square meter place, next to there is a river, I would like to have eel? What kind of cement tank c

20、an be built? How deep? Is the specific method?How big is it to build a cement tank?With the propagation of cement pool each with 2-6 square meters is appropriate; eel pond with each does not exceed 20 square meters. A higher cost pool Xiaojian; too much inconvenience management, is not conducive to

21、raising the size of eel. Eel pool will each built 10 square meters and 20 square meters, 0.1 meters deep, the water in the pool water is 1 cubic meters or 2 cubic meters of water, which is very convenient.How is the depth of the cement pit determined?Generally used for soilless culture of the use of

22、 cement pond, its pool depth of 50-70 cm can be, if there is soil cultivation, the depth of the pond can be further deepened about 20 cm. With the cement pond for soil culture, usually only need to put 10-20 cm thick mud at the bottom of the pool. Mud can be collected directly from paddy fields or p

23、onds, and earthworms can also be used instead of sludge. In general, after placing the mud without hard lumps, no debris, and the overall feeling soft and smooth.What are the basic requirements of Jianshui mud pool?The cement tank can be designed as a square or square. Pool wall made of single brick

24、 (wall thickness 6 cm) or flat brick (wall thickness of 12 cm) can be. Chi Jiao erected a brick, with dust after smooth rounded corners, to prevent the eel into S shape up, with the interaction between the right and escape from the pool, pool also need to build a top wall inward probe brick, prevent

25、 the tank wall along the eel directly jump and escape from outside of the pool effect. The inner wall of the pool and the bottom of the pool are smoothed with cement mortar. One end of the bottom of the pool is provided with a drain hole, and if the water supply is used automatically, a hole is open

26、ed at the other end of the pool as the inlet hole. For the convenience to drain the water, we should be built on the pool, the pool built directly from the ground brick. At the same time, the bottom of the pool should be beveled to make it slightly inclined to the side of the drain.Eel; still water;

27、 soilless cultureFirst, pond preparationThe core technology of the water free soilless culture eel is to utilize the principle of biological diversity and mutual benefit so as to improve the survival rate and growth rate of the finless eel and to prevent and control diseases and insect pests. In ord

28、er to achieve the no water, no water farming of the eel, it is necessary to build a quiet and comfortable home for the finless eel.In the general area of 18 square meters around the pond, pool of high 40-50cm, it is easy to manage, a water inlet is arranged on the south wall, the drain is near the n

29、orth wall of the bottom of the pool, in order to complete sewage; in order to prevent rain water surge, so also in the north wall set overflow and the height from the bottom of the pool about 30cm place. Eel climbing ability is very strong, when the construction of the pool, must build a wall around

30、 10cm, in order to prevent the eel interpretation of the great escape story. Eel live accustomed to pH acid mud nest, and suddenly put it into a high alkaline concentration of the cement pool, it will inevitably acclimatized. So, we must first build fish ponds, with 1/1000 concentration of denitroge

31、nating superphosphate, soaking after a week, put on the water after the water, also check whether pH reached about 6.5, the safest way is to put a few loach, half an hour later, if turn loach belly, or alkaline again, if need denitrogenating, loach intact,Walk freely, at this time, you can buy a hom

32、e for the eel. The eel is timid by nature, love deep, so water without soil in ecological culture, to simulate a dark fish nest is very important, with the old bicycle tires on a black plastic bag is a good idea, also can give the eel a comfortable home, but also can reduce the shooting two birds wi

33、th one stone.Eel likes to flock together, but each has its own personality, so the tyres should be made of big, medium and small sizes, so that they can choose freely and live with each other in a congenial manner. According to our observation to the majority of drilling eel inside the tire, probabl

34、y to 60%-70%, 10%-20% also has a plastic bag inside the drill, and 10%-20% in the grass below, this is because the individual difference of eel is relatively large, the tire according to how much everyone has his hobby, after observing changes like this impertinent land grab, apparently tire less, i

35、n a timely manner to increase, so as to avoid the eel fighting, causing casualties. When you set the nest, you must also notice that the opening of the tire must be outward facing, so that the eel can have enough activities. Food table should be placed in the center to facilitate eel feeding, and al

36、so convenient for managers to observe.As the saying goes, raising fish first, raising water, raising water, raising grass first, so putting on aquatic plants is also one of the key technologies for the no water, no soil ecological farming. In the eel pond, raising water plants can not only adjust an

37、d purify the water quality, but also provide landlords with shelter for the finless eel, so as to shelter from the rain. The more important is that it can play a role in pest control, we confirmed experimentally, especially flavonoids containing the Alternanthera philoxeroides to pests and diseases

38、of eel with gentamicin similar effect. When putting on aquatic plants, the area of the water plants should not be too big. At least four weeks should be reserved for 1/4 space so that the eels enjoy full freedom.There is one point worth noting. The proportion of aquatic plants should be reasonably m

39、atched in different seasons. General summer water hyacinth, Alternanthera philoxeroides, spring and autumn to winter is best not as duckweed and Alternanthera philoxeroides, water. Because love drill eel grass, water grass floating in the water, it is easy to cool winter frostbite eel. To take the a

40、rbor is eel eel pond, no essential soil ecological farming hydrostatic link. This is because the water breeding of eel pond small, shallow water, the water temperature in the summer can easily exceed 30 degrees, the eel with stress reaction, lead to fatal disaster. So be sure to take shelter measure

41、s. It is also a good idea to grow vines, loofah and other climbing plants on the side of the pond. It can not only enjoy the joy of harvest, but also give the finless eel pond a summer shade.Build a fish pond, fish nest, a frame cover, shade net, shop there, then you can not rush to the eel baby ple

42、ase come home, because plants, tyres, inevitably there are parasites, bacteria. It is generally in the fish stocking 15 days ago, Potassium Permanganate with mixture of copper sulfate 10 g / M 3 and 100 g / M 3, full pool splash, insecticidal sterilization, have, for 1 weeks after the change of wate

43、r, can stocking a small fish, loach, toad, escargot, if you think these little guys with eel for power, but that they are wrong, in fact, loach is to increase oxygen forcing, but not more than 0.3 kilograms per square metre, and stocked in eel tame food after the success of otherwise, greedy loach w

44、ill eat eel all rations toad is to eel medical doctor, each pool 1-2 only can, otherwise Shangcuan will drill down, get restless eel. The snail is to remove feces eel handyman, but not more than 0.25 kilograms per square meter, more will compete for oxygen with eel. With such a comfortable environme

45、nt, complete with the workers. Please bring the finless eel home.Two, eels.In recent years, the development of eel farming has been very fast, and the seedlings have shown an embarrassing situation of insufficient supply. This also to the criminals have an opportunity, they carefully concocted some

46、beautiful promises to lure farmers fooled, lied to the country offers a super eel seedling,And called the eel grow fast, easy to raise, from hatching to grow to 1 kg, as long as 7 months. In fact, the so-called super eel seedlings, swindlers who cheat customers after the introduction of funds, and t

47、hen sent people from the market to buy local cheap commodity small eel. Farmers tend to breed after less than a month The whole army was wiped out. never see, the rapid growth of the event. So, want to raise eel farmer friend, in the introduction to the incubating ability of home introduction, local

48、 wild resources, it is best to keep the wild store. Then, wild storage should pay attention to those problems? Back of the wild eel, do not immediately into the pool, the wild eel living environment, inevitably there are bacteria, parasites and so on, to distinguish different specifications accordin

49、g to the size, then disinfected with 3 mg / L of eel treasure No. 1, in order to avoid stocking, put bacteria into the clean ponds. The screening of fish species takes 3 to 4 days to complete, and the poor fish are picked every morning and evening. The quality is poor. What does it include? In four

50、words, check the form view color, as the name suggests, we should first check the eel body, the fish nest, curly tail and tail, the sick eel are eliminated the object; then observe the color of a spotted eel, and the swelling of the mouth and the anus must pick out tens of millions dont let them pas

51、s, mix the soup.In the 3 to 4 days of temporary rearing period, every mornings water exchange work is essential, otherwise it will be caused by oxygen shortage to the eel. In order to kill the eel body parasites and bacteria, but also to eel to eat some Chinese herbal medicine, to eat used to small

52、fish, shrimp eel eating Chinese herbal medicine, is not easy. However, the Chinese herbal medicine feed greedy then, then eat Tenebrio molitor, medicine Tenebrio feed eel, so it has no taboos. Feeding time in the evening, one is not so dazzling sunlight, second, suitable temperature, feeding, grasp

53、the weight of 1% eel, you can, after 3 to 4 days of selection, the body is robust, you can stocking. Before stocking, but also with copper sulfate immersion of 10 mg / L after about 8 minutes, you can let them live in bridal chamber, eel of love, if you eat in the stocking above the table, then it w

54、ill often go back to eating the stage play, it is very beneficial to tame food. Stocking density is generally about 1.5 kilograms per square meter, different specifications into different pools, so as not to big bullying small. Stocking within two hours, we must carefully observe, just arrived at th

55、e new home, inevitably some fighting, so there are no nest, the injured will be eliminated in time. In the evening, artificial feeding will begin.Three. Artificial feedingWhy should artificial breeding eel feed on it? Eel breeding food, which is domesticated eel eat mixed feed. Eel feeding with feed

56、 can make the nutrition more comprehensive and balanced, and provide a good material foundation for the scale breeding of Monopterus albus. It can be said during artificial tame food eel is a measure of the success of an important symbol, we often say, if the eel tame food is successful, then the ar

57、tificial breeding finless eel basic half success. To get used to eat food eat eel feed, like a child eating milk, eat milk as hard, eel Tenebrio molitor is love, so to eat eel Tenebrio molitor as bait, training is a good way to feed. Generally, the first day of Tenebrio molitor accounted for 80%, ot

58、her feed accounted for 20%. After Tenebrio 10% per day to diminishing the amount of feed, with 10% of the quantity increasing, labor element collocation. But Tenebrio not less than 40%, otherwise it can not meet the tastes of the eel.Four, diseaseAs the saying goes, seven in three minutes, very clos

59、e up insurance, so the daily management of eel is very important, many precautionary measures, it is from the experience, so the prevention and cure of diseases and pests sloppy.Water without soil ecological breeding of eel, the three most common bacterial diseases, unfinished nerve disorder, and print disease. General Potassium Permanganate better drug control. 1% Potassium Permanganate concentrate
