Wide mems thin film；
Step 2: raising：
Feeding hack, feeding platform, feeding tray is made with nylon mesh sheet, swamp eel seedling starts to feed fly maggot after launching three days, and it is swamp eel body weight just to have started feeding volume
1-2%, be changed to feed the 3-6% of swamp eel body weight after 15 days, feed during daily 5-6 in afternoon, once a day, bait throwing in is accomplished fixed
When, positioning, determine matter, be quantitative, rainy day not bait throwing in；
Step 3: expelling parasite：
Once, interval expelling parasite again after four days, monthly expelling parasite is once later for expelling parasite after swamp eel seedling is launched ten days；
Step 4: daily management：
1. cleaning and sterilizing：Per two weeks, cleaning nylon wire once, uses quick lime, bleaching powder, potassium permanganate and Chinese herbal medicine after cleaning
Rotation is splashed sterilization water body, while is mended phosphorus to water body, replenished the calcium, mends potassium；
2. water quality management：Fill new water the 6-9 months weekly and change old water once, replacing amount is the 1/4-1/5 of old water, water during arid
45-50 centimetres is maintained at deeply, usually the depth of water is maintained at 40-45 centimetres, splashes EM bacterium once within every 15 days, pulls debris in water out in time
And residual bait, water transparency is kept more than 30 centimetres；
3. the prevention and control of plant diseases, pest control：Trap lamp is installed by the quantity of 5/mu, and installs yellow plate additional；
Step 5: harvesting and sale：
Harvesting list marketing in batches before and after the Mid-autumn Festival, or put net cage and temporarily support, a method for catching puts earthworm for bamboo cage and draws eel method, tea seed cake powder
