ABSTRACT

This study aims to determine the distribution of water quality in the canal network and Sei Teras fishpond under tidal cycle conditions for aquaculture technology. The previous study focused on the water quality upstream of the canals. The result shows that the degree of acidity (pH) met the criteria for advanced aquaculture, while the salinity and total dissolved solids need improvement. This study measured water quality and hydraulic parameters during spring and neap tide conditions. To conduct a calibration process for an optimal roughness coefficient and collect boundary condition data, selected locations of observation points are upstream and downstream of the primary canals, secondary canals, and fishpond. The difference in amplitude in neap and spring tide influenced the flow distribution pattern in the canal. During the spring tide in march 2022, the distribution of water quality was almost evenly distributed along the primary canals with a salinity range of 22.9 – 25.2 ppt, a pH range of 6.89 – 7.02, and a temperature range of 27.9 – 28.3°C. However, during the neap tide, the distribution of water quality was uneven due to low tidal energy. The salinity concentrations in secondary canals and fishponds ranged from 9.8 – 12.1 ppt, pH ranged from 7.03 -8.34, and temperature ranged from 31.3 – 33.6°C. The improvement of advanced cultivation technology could be applied. The salinity parameter meets the criteria to be improved for semi-intensive farming of vannamei shrimp or tiger prawn. Meanwhile, pH and temperature parameters meet the criteria for super-intensive improvement. Good management and the development requirement of intensive farming, such as fishpond preparation, were indispensable to achieving that goal.
