  This research was aimed to study the performance of Zero Water Discharge (ZWD) by using nitrifying bacteria and microalgae Chaetoceros calcitrans in super intensive white shrimp (Litopenaeus vannamei) culture. The study consists of three consecutive steps: (1) activating and cultivating of nitrifying bacteria and microalgae C. calcitrans, (2) conditioning of zero water discharge system, and (3) using ZWD during shrimp culture along with control (a conventional system in which the water was renewed every four weeks and without the addition of nitrifying bacteria and C. calcitrans). Based on water quality parameters, low and stable NH4 + (0.07–0.69 mg/L), NO2 - (0–3.2 mg/L), NO3 - (1.04–4.29 mg/L) were obtained in both systems during culture period. Higher feed amount of 1178.28 g in ZWD system compared to the conventional one contributed to a same level of NH4+ and NO.. View More»
