Abstract

 

Water quality stability is a key determinant of ecological balance and production performance in super-intensive shrimp aquaculture systems. This study evaluated the dynamics of major water quality parameters and identified the environmental drivers influencing shrimp production using multivariate analysis. The study was conducted in three super-intensive ponds of whiteleg shrimp (Litopenaeus vannamei) over a 61-day culture period. Water quality parameters including pH, temperature, salinity, and dissolved oxygen (DO) were monitored periodically, while shrimp production indicators such as survival rate (SR), average body weight (ABW), specific growth rate (SGR), and feed input were recorded. The results showed that pH and salinity were significantly influenced by measurement time, whereas temperature and DO remained relatively stable and showed no significant spatial differences among ponds. The observed pH ranged from 7.61 to 8.89 (mean 8.32 ± 0.21), temperature averaged 29.4 ± 1.15 °C, salinity ranged from 15 to 30 g L⁻¹, and DO varied between 4.7 and 8.5 mg L⁻¹, indicating generally suitable conditions for shrimp culture. Principal component analysis identified three components explaining 72.27% of the total variance. The first component represented the main productivity gradient associated with DO, feed input, ABW, salinity, and survival rate. The second component reflected physicochemical environmental variability dominated by temperature and pH, while the third component was primarily associated with shrimp growth dynamics represented by SGR. These results highlight the strong interaction between environmental stability and shrimp production performance, emphasizing the importance of integrated water quality management in super-intensive shrimp culture systems.
