Assessing the Efficacy of Remediating Episodic Low pH concentrations in Headwater Brook Trout Streams with Clam Shell Additions, Maine
|Project Start Date|
This project will assess if clam shell additions will increase in-stream pH and decrease organic aluminum concentrations in headwater brook trout streams in Maine. Two tributaries included in this study currently do not sustain fish, even though they contain high quality habitat for fish. The likely reason for fish absence is thought to be low pH and subsequently high aluminum. The clam shell industry in Maine currently pays for discarding shells shucked at processing facilities. If this project is successful, it would allow us to use a waste product to help remediate low pH and subsequent high labial aluminum issues in brook trout streams.
