Explanation / Answer

The scientists looked at 28 years' worth of water quality and fish community data gathered from two distinct areas of Lake Erie - the warm, shallow west basin and the cooler, deeper central basin. The Ohio Department of Natural Resources-Division of Wildlife collected the data from 1969 to 1996.

Reductions in phosphorus pollution led to the loss of one-quarter of the total number of fish species in the west basin (from nearly 20 to about 15), while diversity increased by one-quarter in the central basin (from less than 12 species to nearly 15.) Data from the east basin, the coolest and deepest part of the lake, wasn't available.

Phosphorus is a byproduct of municipal and industrial wastewater plants and from fertilizer use on agricultural lands. Too much phosphorus in a body of water can lead to eutrophication - a condition in which algae thrive and use much of the available oxygen near the bottom of the lake. This can, in turn, harm fish intolerant of low oxygen levels, such as smallmouth bass and lake whitefish.
