1. the cultural technique of a Macrobrachium nipponensis(de Haan), it is characterised in that comprise the following steps:

  • 1) requirement of culture pond;

    dig pond in water head site physical features lower, uses artificial diversion, pollution-free, and irrigation and drainage are convenient, pondBottom flat, both sides, pond are 60 °

    of slopes, and pond bottom is provided with the loam of 10cm, and one layer of Maifanitum is laid on loam upper strata;

    PondAnother both sides in addition to slope, the pool are respectively arranged with the aquaculture net cage that row'"'"'s specification is 5m ×

    5m ×

    1m;

    2) front preparation is put in a suitable place to breed;

    putting first half of the month in a suitable place to breed, pond being spread quick lime and bleaching powder, water filling stands 24h and drains, and again notesWater, the water filling degree of depth is 20-40cm, and an aerator is respectively installed, before putting shrimp Seedling in a suitable place to breed in the both sides laying aquaculture net cage in pondCarry out 15 minutes disinfect;

    3) water quality management;

    plantation is dry on slope, pond bends dish, aquatic Rhizoma Iridis Tectori and parasol grass, plants little Dendrobium denneanum Kerr., red line grass at the bottom of pondAnd waterweed;

    Bellamya purificate is thrown in pond;

    Every two weeks spills a crude salt, every day water body is carried out oxygenase 12 hour, 3-Within 5 days, once changing water, quantity of exchanged water is as the criterion with holding water transparence for 30-40cm;

    4) feeding is fed;

    use formula forage and fresh bait material with 4;

    3 mass ratio mixing input mode, formula forage is pressed by followingRaw material according to weight portion forms;

    Pupa bombycis 5-10 part, fishbone powder 10-18 part, Testa oryzae 10-15 part, lecithin 1-3 part, yeast 1-3Part, mineral 3-7 part, Pitaya Flower 8-10 part, bean cake 5-10 part, Os Bovis seu Bubali powder 12-15 part, Semen Camelliae 4-6 part;

    Described fresh bait materialMeat paste is broken into for one or more in shrimp, Lumbricus, small fish and Bellamya purificate;

    5) throw something and feed feedstuff;

    the aquaculture net cage in step 1 is arranged 3 ranks, respectively first level, second level, the third levelNot, the aquaculture net cage of first level is set to 10-15, throws in 3000-4000 tail shrimp Seedling in single casing, supporting of remaining rankGrow net cage and be disposed as 3-5;

    Every day throws something and feeds 3-4 time, throws something and feeds half an hour every time, feeding amount be followed successively by from throwing something and feeding first 1 part, 2Part, 3 parts, 5 parts;

    First level aquaculture net cage day feeding amount is the 5~

    8% of monomer weight, second level aquaculture net cage day feedingAmount is the 8~

    10% of monomer weight;

    Third level aquaculture net cage day feeding amount is the 10~

    12% of monomer weight;

    Every 10 days toShrimp Seedling in one rank aquaculture net cage measures, and the shrimp Seedling that monomer height exceedes mean lengths 20% is chosen and removed, and delivers to downIn one rank aquaculture net cage, isolation is fed;

    It is 10+2n days that the time is selected in the other measurement of next stage, and wherein n is this aquaculture net cageNumber of levels, when in third level net cage, Macrobrachium nipponensis(de Haan) monomer height is pulled out and put when reaching 2.5-3cm and raises scattered to pond;

    6) rational fishing;

    the Macrobrachium nipponensis(de Haan) monomer body length person that reaches more than 4.5cm in pond, fishes for sale.
