The former covered water temperature and pH in the spawning, nursery and rearing ponds, in the morning, 06:00-07:00, at noon,12:00-13.00, and in the afternoon 17:00 to 18:00. Measurements were taken for 2 weeks. The latter included Dissolved Oxygen (DO), Ammonia, Nitrite, Carbon Dioxide (CO2) and turbidity. Water samples were analyzed in the Laboratory of Freshwater Aquaculture Center (BBAT) Tatelu, North Minahasa. Results showed that water temperature, pH, DO, CO2, turbidity, ammonia and nitrite were in the suitable range for the freshwater lobster culture, except that DO, CO2, turbidity, ammonia in the spawning and rearing ponds on March 14, 2011 were either lower or higher than the National Water Quality Standard for aquaculture.
