Colorado Division of Wildlife. Federal Aid Study F-51. Fort Collins, Colorado. Fryingpan River The purpose of this study was to evaluate the success of newly imposed fishing regulations in improving the health of the rainbow trout population in the Fryingpan River. In 1981, stricter regulations were placed on fishing downstream of the dam in response to declining rainbow trout populations. Due to high egg mortality caused by hypolimnetic releases from Ruedi Dam, rainbow trout populations were augmented by the release of fingerlings in 1981 and 1982. Through the use of electro-fishing and creel studies, the rainbow trout population was found to be increasing by 1983. Planted fingerlings were surviving, growing, and competing well with the existing brown trout. The new fishing regulations and stocking programs were supported as the causes responsible for the improved condition of the rainbow trout population in the Fryingpan River. Nehring, R B. and R M. Anderson. 1985. Stream Fisheries Investigations. Colorado Division of Wildlife. Federal Aid Study F-51. Fort Collins, Colorado. Fryingpan River The purpose of this study was to evaluate the continuing success of a management strategy for the Fryingpan River that consisted of catch and release restrictions and a fingerling release program. Success was seen in catch and release areas with the increase of rainbow trout populations. This was in contrast to areas with a one rainbow trout one brown trout limit where the populations are still not showing sufficient recruitment. Rather than expand fishing restrictions, it was recommended that the population be fixrther augmented by advanced fingerling introductions. Nehring, R B. 1986. Stream Fisheries Investigations. Colorado Division of Wildlife. Federal Aid Project F-51-R Fort Collins, Colorado. Fryingpan River This study sought to evaluate the progress of the management program for rainbow trout in the Fryingpan River. Continued monitoring offish populations has shown that rainbow trout numbers have increased in the catch and release areas. Evidence is reviewed which demonstrates that the rainbow trout population will not remain viable without further protection and augmentation.
