Organic fish farm. Part of the wastewater treatment system at the Binca Seafood organic aquaculture farm, Vietnam. This farm breeds and processes Pangasius hypophthalmus and Pangasius bocourti catfish for the food market. The scattered stones in this channel help the evaporation of ammonia produced from the fish waste. Before the water is allowed back into the wild a treatment pond redulates the acidity using a misture of plants.
