Characteristics of the aquatic environment as a basis for brackish water pond development in the Padang Pariaman regency area, Indonesia

Abstract

Abstract The coast of Padang Pariaman Regency is one of the shrimp productions centra area in West Sumatera Province. This study aims to show water conditions in aquaculture areas for vanname shrimp pond. Carried out every month through insitu and exsitu water sampling and analysis in 6 locations from May-July 2022. Observations were made on water physical-chemistry parameters (temperature, pH, salinity, dissolved oxygen-DO, COD, ammonia, TSS and phosphate). Data were analyzed descriptively, compared with environmental quality standards for biota based on decree of Government Number 22 of 2021. Based on the analysis, it is known that the range (and standard deviation) of water quality varies, namely temperature 26.7-33.5 °C (29.79±1.93 °C), pH 7.37-8.8 (7.86±0.31), salinity 25-36 ‰ (29.83±2.94 ‰), DO 6.01-8.90 mg/l (7.70±0.99 mg/l), ammonia 0.01-3.25 mg/l (1.65±0.91 mg/l), phosphate 0.03-0.33 mg/l (0.18±0.09 mg/l), TSS 2.03-14.46 mg/l (4.49±3.32 mg/l), and COD 17.6-88.0 mg/l (54.76± 21.25 mg/l). Based on the observations, it can be concluded with the condition of the brackish pond waters is good for the development of vanname shrimp aquaculture.
