Natural bait the biology such as phytoplankton and zooplankter etc. of the big water body such as the influence that temperature gradually decreases, rice field and pond are difficult to train
It supports, biomass is on the low side to cause shrimp seedling bait insufficient, and 1cm shrimp seedling slow growth even sinks into stagnate.November to December simultaneously,
Water temperature declines rapidly, and shrimp seedling is overwintering into hole one after another, causes activity space limited.Inanition and activity space, which are limited, leads to small dragon
Shrimp shrimp seedling is nibbled mutually, and survival rate is usually no more than 60%；Shrimp seedling specification also very little in March after overwintering, does not grow to mostly
3cm, and specification is very irregular, need to grow into mostly can just grow into 30 grams or more of commercial sized prawn specification by the end of May.It is another
Mode is to launch close shrimp mode, i.e., annual August to September is launched close shrimp into rice field or pond in the ratio of female-male proportion 2:1,
Close shrimp natural mating, oviposition, incubating oosperm are all very asynchronous, and shrimp seedling successively generates after 2~5 months successively, i.e. October
Bottom is emerged successively by the end of February to second year, thus can not collect also can not be breeding graded for shrimp seedling.This mode, which is removed to have, launches shrimp
Outside all disadvantages of seedling mode, weed survival rate has emergence quantity uncontrollable asynchronous with seedling-growing time more down to 50%
The irregular equal more serious disadvantage of caused shrimp seedling specification.
Upper two kinds of cray aquaculture models all do not carry out seed hierarchical culture, and weed survival rate is low, and the speed of growth is slow, specification
