Fangtao laying aside around the pond nets, Fangtao 60 cm deep underground , the earth erected 100 cm , on the network link, using bamboo support. Each of the four ponds with a motor-pumped wells , pumps with 5.5 kilowatts per hour, more than 80 cubic meters of water supply to achieve micro-water exchange , it will ensure the hot season cooling demand, but also to ensure the pool is not hypoxia. 2 , stocking lobster traps. 10 days before stocking , clearing of loach pool , remove excess silt, check Fangtao fence, loopholes , dredge into drains . Because lobster traps for neutral or slightly acidic environment in the growth, it is not clear pond with quicklime , the available concentration of 10 mg / kg of the bleach pond .

Pond water is good or bad for the lobster traps growth and development is extremely important. By casting organic fertilizer, adjust color is yellow-green , transparency is about 30 cm , pH neutral or slightly acidic to keep micro-flow .

    If the water is too thin , high transparency , should be appropriate topdressing fertilizer.

Mainly to strengthen Xuntang observe the activities of lobster traps , water quality changes , lobster traps feeding situation , facility operation , etc. , and make a record . Hot season to keep micro-water , new water every day , day exchange capacity of 10 % or more. Daily feeding time , to observe whether the lobster traps fled network , the check because voles chewing , careless operation resulting in Fangtao damaged .
