Current Management
Currently, the largest threat to E. caeruleum is run-off and pollution due to urbanization. For instance, one study found the development of an interstate highway negatively affected the abundance of several fish species, including E. caeruleum, because of decreasing quality of water of the nearby creek. Therefore, monitoring run-off and pollution draining into rivers and streams is important due to the adverse effects they could have on fish communities. Currently, management plans consist of reducing nutrient, pesticide, and sediment loadings within such streams. This same study suggests conservation practices should be a combination of both physical habitat monitoring and water chemistry monitoring, because it would benefit fish communities within headwater streams more than just implementing one conservation practice or the other. Although broad management plans are in place for many rivers and streams and their fish communities as a whole, no current management plans in place are specifically designed for E. caeruleum. The lack of protection is probably because it is one of the most abundant darter species. Although the rainbow darter may be abundant now, many other darter species have become endangered or extinct.

Famous quotes containing the words current and/or management:
“Without the Empire we should be tossed like a cork in the cross current of world politics. It is at once our sword and our shield.”
—William Morris Hughes (1864–1952)
“This we take it is the grand characteristic of our age. By our skill in Mechanism, it has come to pass, that in the management of external things we excel all other ages; while in whatever respects the pure moral nature, in true dignity of soul and character, we are perhaps inferior to most civilised ages.”
—Thomas Carlyle (1795–1881)
