Fish Resources and Water Quality of an In-Stream Gravel Excavation Pit in the Naugatuck River, Connecticut
The fish assemblage and various water quality parameters were sampled during 18-22 July 1988, at a 1,550-m-long in-stream gravel excavation pit and three adjacent riffles located on the Naugatuck River about 6 km south of Thomaston, CT. The purposes of the study were to determine the quality of fish...
