Two continuous grow-out experiments of red-tailed shrimp Penueus penicillatus were conducted for one year in a super intensive system with a stocking density of 171 and 286 postlarvae/m², respectively. The postlarval shrimp (Ph_8–12) were cultured in three 0.14 ha earthen ponds with concrete dikes. The shrimp were fed with a commercially prepared feed four times a day. Water quality parameters from the second trial varied as follows: water temperature from 23.0 to 30.4 C, salinity from 15.33 to 21.00 ppt, dissolved oxygen (DO) from 3.47 to 7.34 mg/L, NH₃-N from 0.002 to 0.869 mg/L, nitrite-N from 0.013 to 0.844 mg/L, and nitrate-N from 0.021 to 1.795 mg/L. Ammonia-N increased from 0.022 to 46.110 mg/L, while the pH declined from 8.12 to 7.32. Yield was 4,650 kg/0.42 ha from the first crop in 131 days and 5,160 kg/0.42 ha from the second crop in 141 days. The productivity of this system producing P. penicillatus was 11–12 tons/ha/crop.  相似文献
