Data on anglers' catches, the growth and migration of stocked trout, and the efficiency of fall and spring plantings were obtained by means of a creel census in Spring Creek, Pennsylvania, during 1939. Of 2,130 tagged trout planted, 50.8 per cent were recovered by anglers. Due to heavy fishing pressure, more than 40 per cent of all tagged trout taken during the entire season were removed on the first day. A high first-day kill (76 per cent of the total recoveries) of brook trout was noted. The quality of fishing declined rapidly during the early season. Fishing for brook trout was good for only a few days, brown trout fishing was fair for about a month, while rainbow trout fishing lasted slightly longer. Catches of tagged trout after 6 weeks were negligible. Only 10 trout were recovered during 1940 and 1 during 1941. Six of these fish were brown trout and 5 were rainbow trout. There was no evidence that any brook trout survived from one fishing season to the next.
