Abstract
An interview-count sport fishing survey was conducted from January through April, 1970, along a one-mile discharge canal of the Potomac Electric Power Company’s Steam Electric station located at Chalk Point, Maryland. An estimated 20,335 fishing trips, representing 77,943 hours of fishing, were made during the period sampled. On interview days, 8,758 fishermen were counted, and 4,716 were interviewed. An estimated 58,453 fish, representing 9 species, were taken, with an average of 0.71 fish caught per man-hour of effort. White perch,Morone americana, dominated the catch during all months sampled. No significant correlation could be made between water temperature of the canal and number of fish caught per man-hour of effort.
