Commercial pangasius farming has presented significant challenges to local environment in Dong Thap province, primarily due to the direct disposal of pond sediment and pond wastewater. The purpose of this research is to improve resource utilization efficiency in the commercial catfish farming system in Hong Ngu district, Dong Thap province. Before selecting suitable waste treatment solutions, a material flow analysis was performed on the fish farming process. Water hyacinth ponds were used for wastewater treatment, and pond sediment composting was used to grow vegetables. Instead of disposing of 353 tons of pond sediment directly, the composting treatment was intended to reduce this amount. Composting pond sludge provides nutrients for growing mustard greens. The quality of the after-treatment wastewater was improved. The removal rates of BOD5 , COD, and NO2 -N in the pond's wastewater were 76.62%, 76.92%, and 77.89%, respectively, while NO3 -N was not detected. The water quality standard for direct discharge into the environment is met by these results. When compared to the current traditional farming system, these treatment solutions increased household income by 6,825,000 VND for a fish farming crop.
