Description
Technical field
The invention belongs to agricultural product cultural technique field, relate to a kind of blue crab cultivation system.
Background technology
Mud crab is a kind of delicious meat, and is nutritious, has the effect of nourishing and fit keeping function concurrently.Especially female crab is regarded as " cream crab " by the southern china people, and the title of " marine genseng " is arranged.Abound with in warm shallow sea, mainly be distributed in the ground such as coastal in Chinese Guangdong, Guangxi, Fujian and Taiwan, Jiangsu and Zhejiang Provinces one band is outstanding many.Mud crab contains rich in protein and trace element, and health is had good tonic effect.At present, to 250 yuan/kg of market price in winter, the price of soft-shell blue crabs is higher, and supply falls short of demand especially.Therefore adopting novel cultivating system to culture, is the only way which must be passed that industry promotes.
Well-known crab class is a kind of very violent marine organisms, and large tracts of land pond culture mud crab is because the mud crab shelling is irregular; It is very severe to cut one another's throats; Survival rate only about 20% adds that marine pollution in recent years is serious, disease takes place frequently, and has a strong impact on the output and the benefit of blue crab cultivation.Therefore, press for level and the benefit that a kind of new cultivating system promotes the crayfish culture industry.
The cultivator of the disclosed a kind of blue crab fried intermediate rearing of general blue crab cultivation such as patent (CN 201160430Y); Be provided with 1 group of Cultivation container and support frame; 1 group of Cultivation container is arranged in the support frame, and Cultivation container is provided with etting stationary pipes, etting and etting retainer plate, and etting stationary pipes and etting retainer plate are used for fixing etting; The top of etting is fixed on the etting stationary pipes, and the bottom of etting is fixed on the etting retainer plate.This device can improve juvenile crab and culture efficient, but this device also exists defective, and etting retainer plate ratio is easier to fragmentation, causes juvenile crab still to be absorbed among the natural each other cannibalisation.
