The suitability of location batu angus bitung for aquaculture in terms of several physical and chemical parameters of water quality

Aquaculture activities require appropriate and supportive environmental requirements to live and develop optimally, this study aims to (1) Analyze the physical and chemical parameters of water quality in Batu Angus waters, (2) Evaluate the suitability of water quality as a potential aquaculture location in Batu Angus waters. This research was conducted in the waters of Batu Angus Bitung in July - August 2022. Water quality analysis was carried out by measuring the parameters of depth, temperature, salinity, pH and oxygen carried out in situ using a Multipurpose water quality tool (Horiba U-52G), measuring current speed using a Current floating meter and measuring brightness using a Secchi disk tool. In situ data collection of seawater samples at 3 stations (St) was carried out 3 times with a time interval of 2 weeks at 05:00, 09:00, 13:00, 17:00 and 21:00 WITA. Meanwhile, ammonia, nitrate, nitrite and phosphate measurements were carried out using the spectrophotometer method at the Manado Industrial Research and Standardization Center Testing Laboratory. The results of the suitability analysis show that the Batu Angus Bitung water area is very suitable for aquaculture activities.
