Loose shell syndrome is a chronic disease in shrimp industries, in the present study, two different L. vannamei grow-out ponds (normal and LSS infected ponds) were selected to study their water quality parameters. Average Body Weight (ABW) and Daily Growth Rate (DGR) in Prakasam district of Andhra Pradesh. The results of the present study showed, there was no much variation in water quality parameters between both the ponds except pH. The daily growth rate and average body weight was higher in the normal pond than LSS infected one. The maximum LSS prevalence was reached up to 20%. The infected shrimps became sluggish and negative allometric growth. The results of present study revealed that the LSS infected shrimps showed lower production in the grow-out pond.
