摘要：

Measurement of nine water quality parameters were performed every two weeks in two shrimp farms for one production cycle, located in Tuban and Probolinggo, East Java Province, Indonesia. The average productivity for Farm 1 was 17,142.86 kg/ha, with an average size of 17.88 g; while the productivity for Farm 2 was 18,333.33 kg/ha, with an average size of 14.36 g. During the shrimp cultivating period, mean values for salinity, pH and dissolved oxygen (DO) in both the farms were significantly different, whereas temperature in both the farms was not different. TAN, nitrite and orthophosphate concentrations in both the farms were not different. But for nitrate and TSS, the levels are higher in Farm 2 than in Farm 1. The authors conclude that, compared with Farm 1 (water exchange and earthen pond), Farm 2 (zero-water exchange and lined pond) had significantly higher survival rate and higher environmental profits.
