| Abstract | ||
| Suaran Village, located in Berau Regency, East Kalimantan Province, is an aquaculture area with tiger shrimp (Penaeus monodon) as its primary commodity. Farmers practice traditional farming, relying on natural inputs without supplemental feed or chemical treatments. This study aims to evaluate the physicochemical water quality and plankton density in the ponds, both of which are critical parameters in traditional shrimp aquaculture. The research was conducted in an aquaculture zone covering approximately 5,404 hectares, consisting of shrimp ponds, mangrove forests, riparian buffer zones, and river systems. Data were collected from four stations and used to analyze the spatial distribution of water quality parameters and plankton density using interpolation techniques—specifically, the Spline with Barriers and Kriging methods. Pearson correlation analysis was applied to assess interactions among all measured parameters. Results indicated that temperature (28–31 °C), pH (7.1–9), dissolved oxygen (4–6 mg/L), and conductivity (423–3,900 mS/cm) generally remained within favorable ranges for P. monodon culture. Pond salinity was relatively low (8–15 ppt), which, despite the species’ broad tolerance, may impose physiological constraints during early developmental stages. Plankton density ranged from 1,650 to 2,275 ind/L, reflecting overall adequate natural productivity, although some locations exhibited suboptimal concentrations. These measurements are influenced by environmental conditions and seasonal variations, making them inherently dynamic. Overall, the results contribute to a better understanding of ecosystem dynamics and can support improved water quality management practices in the aquaculture zone of Suaran Village. | ||
