Abstract Share this page

The use of stratified periods, random sampling days and voluntary information provided by the participating anglers provided a method of creel census which required a minimum of working days and still allowed constant highway travel in the working area to flow uninterrupted. A maximum of two men on 24 days was used to census a season total of nearly 7,000 anglers on 24 miles of the stream. In 1952, of 1,107 anglers interviewed 940 (84.9 percent) returned catch data. In 1953 1,140 anglers were interviewed and 1,042 of these (91.4 percent) responded. Total estimated catch was 47,772 in 1952 and 46,997 in 1953. Hatchery-reared rainbow trout comprised 2,223 of the 1952 catch and 4,867 of the catch in 1953. Recovery of these planted fish amounted to 37.1 percent of 6,000 released in 1952 and 57.9 percent of 8,400 in 1953. Anglers retained an estimated 58.5 percent of the total catch in 1952 and 72.2 percent in 1953. Statistical analysis proved the estimate of the total reported catch to be within the limits desired for management purposes.
