The parameters pH (21 and 24◦C – 7.9 ± 0.1; 27 and 30◦C –7.9 ± 0.2; 33◦C – 7.9 ± 0.3), salinity (21 and 24◦C – 33 ± 0.6; 27 and30◦C – 33.6 ± 0.7; 33◦C – 33.2 ± 0.4), alkalinity (21◦C – 177 ± 30.3;24◦C – 172 ± 28.4; 27◦C – 156 ± 32.2; 30◦C – 161 ± 41.7; 33◦C –166 ± 47.0 mg L−1), NO2-N and NO3-N levels did not differ signifi-cantly among the treatments. TSS levels were higher at 30◦C and33◦C (Table 1).The mean shrimp weight increased significantly with tempera-ture throughout the experimental period (Fig. 1). Shrimp reared at30◦C and 33◦C showed significantly greater weekly growth. HigherFig
