BOD in ,aquaculture, ponds. In ,aquaculture, ponds, BOD 5 rarely exceeds 30 milligrams per liter, and most values will be below 10 milligrams per liter. The oxygen demand is expressed more slowly in ,aquaculture, pond effluents than in most ,wastewater,, because the main source of oxygen demand is respiration by living plankton in pond effluents.

The purpose of ,effluent, standards for phosphorus is to reduce phosphorus loads to natural waters and prevent eutrophication. Phosphorus and nitrogen concentrations generally increase simultaneously in effluents, and procedures that lower phosphorus loads usually will reduce nitrogen loads. This is certainly the case in ,aquaculture, ponds.
