It actually depends on whether the individual eels you are raising are about the same size. If there is a size. When it is hungry it will eat the small eels. You can raise up to about 10 eels in one square meter. It also depends on your water quality and water depth. The net box is about $45 a piece, 15-20 pounds of fry is about $450, compound feed is about $120, fresh bait is about $150, and medicine is about $20. \x0d\\\x0d\ I. Construction of Eel Ponds\x0d\ Breeding ponds are constructed with cement and brick surfaces so as to prevent eels from escaping by drilling holes, and the perimeter edges of the ponds should be inclined at an angle to the inside of the ponds to prevent eels from escaping outside the wall by hooking their tails. The general depth of the breeding pool is about 1.5 meters, and the bottom of the pool is covered with clay containing more organic matter, with a thickness of about 20 centimeters. In the pool can also be put into the larger stones, tiles, tree trunks, etc. to make artificial caves, simulated into the natural living environment of eels. In such an environment, eels love to live in such caves, no longer in the bottom of the pool holes to escape, to be in winter, uncovered this kind of cover, piles, you can find many eels living together, but also very easy to catch. After laying a good substrate, you can put fresh water into the pool, the water depth is maintained at about 10 centimeters, should not be too deep, because the eel is used to living in the cave, the head is often to stretch out of the hole to forage for food or breathing, so the depth of the environment, suitable for the eel's living habits. Pool can be appropriate to plant some aquatic plants such as peanuts, cecrops, and improve its water environment, summer can be shade and reduce water temperature, can also be stacked in the pool some rotten grass, eels love to inhabit them, the organic matter in the grass can also cultivate a large number of plankton for eels to eat. Family eel farming, it is appropriate to choose a sunny, ventilated, water convenient place to build a pool in front of the house, behind the house. The size of the pool depends on the scale of breeding, the pool shape can also be combined with landscaping, round, oval, square and irregular shape can be used, but also the use of low-lying puddles, waste fish ponds and waste dung pits reconstruction. \x0d\2, selection and placement of eels \x0d\2, the pool must be sterilized before releasing the seedlings. In 7 to 10 days before the release of seedlings, lime sterilization pool, per square meter of pool with lime 0.2 kg, to kill harmful germs. The eel fry stocked requires no disease or injury, the weight of each tail is 20-30 grams is good, so that the eel seedling adaptability, fast growth. The eel seedling requires neat specification, size is basically the same, so as not to compete for food and kill each other. General per square meter put eel seedlings 50 to 60 tails. \x0d\3, eel feeding management \x0d\1, eel diet eel is animal-based omnivorous fish, can feed earthworms, tadpoles, fly maggots, small fish and shrimp and snail meat or other animal scraps, but also feed a small amount of bran, vegetable leaves, melon and fruit peels. However, it should be noted that eels like to eat fresh bait, rotting and spoiled bait do not feed.　　2, the feed put eels into the eel pool after 3 days do not bait, to be 3 days after the eel activity can be normal bait. The eels have the habit of feeding at night, baiting time can start in the evening, and then gradually early feeding time, after a period of domestication, can be fixed at 10:00 a.m. or 3:00 p.m. baiting. \x0d\baiting amount should be changed according to the change of water temperature, the optimal temperature for eel growth is 15-30 ℃, in this temperature range should be more bait, the general amount of dry bait can be according to the pool of eels in the total weight of 3%-5%, fresh bait bait can be according to the pool of eels in the total weight of 5%-10%, the temperature is lower than 15 ℃ or higher than 30 ℃, less bait, and at the same time baiting according to the The principle of "four fixed" (timing, positioning, quality, quantity) baiting. \x0d\3, daily management of eel farming should do scientific baiting, to prevent the deterioration of water quality, and often keep the water quality fresh, every 2 days to change the water 1 time, the high temperature season can then deepen the pool water. When the weather is hot, to prevent the lack of oxygen in the water, take the water to increase oxygen or other oxygenation measures to ensure that the dissolved oxygen in the water. When it rains heavily, check whether the overflow is smooth, whether the fence is solid, timely drainage to avoid eels escape with the rising water. At the same time should also pay attention to prevent heat, frost, prevent the temperature difference is too large, often adhere to the patrol pool. Once found problems, must be dealt with in a timely manner.
