Effect of Photosynthetic Bacteria (PSB) on the System of Breeding Chinese Mitten Crab
Abstract:
The influence of photosynthetic bacteria (PSB) on the systerm 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 carring capacity of the ecosystem.
