Oxygen levels are rarely limiting, although areas of high organic input should be avoided. The pH of the water is an important factor because extreme values can directly damage gill surfaces. It is also important because it affects the toxicity of several pollutants, including ammonia and cyanide, and heavy metals such as aluminium. 5. 5, and because it is well buffered and is less prone to fluctuations than freshwater. The effects of turbidity can be significant, but depend to a large extent on the nature of the suspended particles.

Where the interactions of these influences have been analysed rigorously, the optima for growth do not necessarily coincide with those for the most efficient food conversion, and compromises in setting conditions must be made. 6 Hydrogen Sulphide Hydrogen sulphide is a noxious gas and is a product of anaerobic decomposition of organic material.
