As shell in 4~6 days 1 time；Juvenile prawn is to sexal maturity stage, shell in 8~10 days 1 time.The shell phase of lobster is 4 annual~October,
But 5~June is peak period.Cray has hibernation habit, and by the hibernation of some months, intracorporal energy consumption is very big, body
Crust also grow thicker, spring lobster crawls out in cave, starts largely to ingest, while in order to mushroom out, it is necessary to slough off
Fall crust.9~October is the breeding period of lobster, and shell significantly reduces.
In cray breeding process, a large amount of mineral trace element need to be absorbed from water body, and (absorption of especially phosphorus is big
In the demand of other microelements such as calcium, iron, copper) meet normal growth needs, lobster inhaled due to microelements such as phosphorus, calcium
The crust that the deficiency of receipts will lead to lobster cannot be shelled, be hardened, and form soft shell or the unsuccessful phenomenon of shelling, the speed of growth slow down.
