APPLICATION OF FERMENTED FEED ON SHRIMP CULTURE

As the improvement of shrimp culture history in main region and countries, the variation of the climate worldwide, the pollution of water resource and shrimp pond, the successful rate and production of shrimp culture falling down year by year, especially affected by shrimp diseases such as EMS, EHP, etc. The essence behind this phenomenon is the aging pond and instability of the water quality in the shrimp pond.

With this background, the fermented feed was studied by Sheng-Long Bio-Tech Company of Haid Group, which is considered to be the revolutionary product in shrimp culture in China. Totally, five strains of beneficial bacteria such as Bacillus, Photosynthetic bacteria, Lactic acid bacteria, Streptococcus faecalis and yeast added. To improve the synergistic effect, beneficial bacteria quantity level internal and external of the shrimp, all of the beneficial bacteria were compounded by orthogonal test, to guarantee the balance of beneficial bacteria in the shrimp gut and the balance between beneficial bacteria and beneficial algae in the pond water.

According to the farm test in Vietnam, the farmer who applied with fermented feed frequently can benefit from this product as follow: the survival rate of PLs increased by 15%, the FCR reduced by 0.15, the production of pond increased by 12%, the successful rate of shrimp culture improved by 16%. Above all, the vibrio in the gut and hepatopancreas can be controlled in safety level, which leads to improve the successful rate and production of shrimp culture.
