In this study, we investigated the related factors that affect mortality rate during the transfer of Penaeus vannamei larvae from large culture pond to small culture tanks. The results showed that the average survival time of P. vannamei under different conditions was about 10 days. The results of Vibrio detection showed that P. vannamei from shrimp farms mignt be Vibrio carriers. During the culture of P. vannamei, water qualities (temperature, salinity, dissolved oxygen, pH, ammonia nitrogen, nitrite, etc.), pathogens, stocking densities, physiological conditions and the operation techniques could affect the survival of P. vannamei.
