Effect of Photosynthetic Bacteria (PSB) on the System of Breeding Chinese Mitten Crab

摘要

The influence of photosynthetic bacteria (PSB) on the system of breeding Chinese mitten crab was studied. Results showed: with the use of PSB, the vibrio bacteria reduced by over 10 times, the nitric bacteria rose 5 times, and the nitrous bacteria rose 1.9 times. The survival rate of the Chinese mitten crab larvae were increased by 32.7%. The use of PSB in breeding Chinese mitten crab system could improve bacteria population and water quality evidently, enhanced the caring capacity of the ecosystem.
