All of those facilities discharge wastewater, treated or untreated, into freshwater environments. Fish farm effluents are known to contain nutrients and chemicals, but the potential impact to surface water quality from these effluents is largely unknown. This study measured standard water quality parameters in different locations (upstream, effluent and downstream) in streams and rivers receiving effluents from fourteen land-based fish farms. There were significant increases in total phosphorus (TP), total nitrogen (TN) and ammonia at the effluent discharge locations compared with upstream, and all of those parameters remained above background at the 100m downstream locations compared to the upstream locations. This suggests that impacts from TN, TP and ammonia may extend further than 100m downstream from effluent outfalls.
