（3）Close shrimp feeding：80% plant feed and 20% animal fodder are fed, starts the 2- that feeding volume is close shrimp body weight
3%, it is stepped up later, feed sooner or later once, evening feeding volume is the 70% of one day feeding volume；
（4）Water quality management：Per water 1 time is changed within 10-15 days, quantity of exchanged water was the 1/3 of water, per 20 days every cubic metre of water body quick lime
20-25 gram is changed water full pool spilling head 1 time；
（5）Breeding and hatching：Breeding keeps 20-25 with water temperature during hatching0C, when finding a large amount of young shrimps, should collect seedling in time；
（6）Shrimp seed rearing pond is built：Training nursery pond compares 1 using slope:2nd, the Tu Chi of depth of water 0.5-1 rice, must have abundant water resources, water quality compared with
It is good, enter draining conveniently, escaping-preventing facilities are built up, pond disinfection is carried out, per mu of 500-800 kilogram of dung polluted water for applying to become thoroughly decomposed is cultivated young
The natural bait of shrimp eating, is arranged outside tree root, thick bamboo tube in pond, also to throw in heavy water and fluitante；
（7）Young shrimp is put in a suitable place to breed：Young shrimp stocking rate is per square metre and puts 150-230 tails, and shrimp seedling specification is consistent, and selects fine day morning
Morning or cloudy day throw in；
（8）Young shrimp is fed：The 1st week after putting in a suitable place to breed, feeds bean milk, feeds 3-4 time daily, and each feeding volume is the young shrimp 0.1- of every ten thousand tail
0.2 kilogram, start within the 2nd week to feed 80% animal fodder and 20% plant feed, each throwing of early, evening 1 time, evening feeding volume
For the 70% of one day feeding volume.The young shrimp of day feeding volume early stage every ten thousand tail is 0.25 kilogram -0.40 kilogram, later by shrimp body weight in pond
10-12% feed, in cultivating process, per water 1 time is changed within 7-10 days, water 1/3 is changed every time, keep the mg/litre of water dissolved oxygen amount 5
More than, water full pool spilling head 1 time is ashed with 20-30 gram of calculogenesis per 20 days every cubic metre of water bodys, cultivate 25-30 days.
It is described（3）In plant feed refer to fresh pasture and water, soybean cake, Testa Tritici or mixed feed one or more mixing, move
