Abstract:

The study aims to assess the effect of Chinese herbal complex in combination with microbial bacteriocide on the farm-scaled culture of Eriocheir sinensis. Using water quality, cumulative death count and farming performance as evaluation indexes, the application effect of Chinese herbal complex (10 g/kg feed, twice per day) and microbial bacteriocide (3.75 kg/hm 2, once every 10 days) in combination on the aquaculture of E. sinensis was observed for 130 days. In comparison with the traditional culture of E. sinensis, the combination of Chinese herbal complex and microbial bacteriocide could significantly improve the aquaculture water quality with the reduction of ammonia, nitrite and increase dissolved oxygen in aquaculture water, greatly decrease the cumulative death counts of crabs for 130 days by 91.3%, and remarkably enhance the yield and output value per hectare by 40.9% and 61.9%, respectively. This study confirms the significant effect of the combination of Chinese herbal complex and microbial bacteriocide on the farm-scaled culture of E. sinensis, and can provide a scientific basis for the development of high-efficient culture techniques of E. sinensis.

Key words: Chinese herbal complex, microbial bacteriocide, Eriocheir sinensis, application effect
