Bioindicators And Water Quality

You cannot check and observe the quality of water all the times, by using Australian Institute of Marine Science"bioindicators" you can infer the water quality not directly but you can.

These are organisms, chemical markers or biological procedures whose transform spot to changed environmental situation. While straight sampling of Australian Institute of Marine Science"bioindicators" gives information about the circumstances at the time of sampling only, bioindicators offer a time-integrated approximation of past environmental situation.

Time scales can depend on the real indicator selected. So they serve to notice changes in water quality even when you don't have the measurements of water quality or are too variable.

For example, a reduced profusion of large foraminifera (marine micro-organisms) or the darkening of coral pigmentation may point out that a reef has been uncovered to poor water quality for some weeks or months.
