Doser Study in Maryland's Coastal Plain, 1992: Use of a Limestone Doser to Mitigate Stream Acidification

摘要

The 1992 doser study was designed to determine the efficacy of an automated limestone slurry doser to neutralize acidic pulses and enhance fish survival n Bacon Ridge Branch; measure physicochemical parameters and trace metals at Bacon Ridge Branch and North River during rain events; assess the use of Bacon Ridge Branch, North River and South River primarily by yellow perch and to lesser degree by white perch, blueback herring and alewife as spawning and nursery areas; evaluate the impact of the 1991 yellow perch stocking in Bacon Ridge Branch and North River and assess stream status in Bacon Ridge Branch and North River by evaluating fish community structure.
