Elemental sulphur is oxidized to sulphuric acid by bacteria. The most harmful effect of pyrite oxidation is caused by the excessive amount of sulphuric acid produced, which if not neutralized by exchangeable bases, creates strongly acid conditions. It is not only the existence of sulphate soils at the time of site selection that has to be taken into account, but also the potential for acid conditions to develop as a result of drainage when pond farms are constructed.

After repeated stocking with imported eggs and juveniles, many of them have established successful hatcheries. Where they have been managed properly, trout culture has become a commercial activity.

It is believed that stocking has contributed significantly in many areas, although the results are not always amenable to cost–benefit analysis.
