Steve G, if you get into the big fish vs more fish debate here you may not like the trend in the responses. Given the response to a similar question in a questionnaire handed out at the wild trout summit this past summer, around 70 percent of the anglers chose the expectation of more fish in special reg areas rather than bigger fish. A review of all wild trout stream data in Wisconsin also revealed that the average lengths of Brook and Brown trout decreased as density increased. No surprise there, but taking that a bit farther it suggests that no-kill in streams that tend to build up high densities of small fish, such as limestoners and moderate fertility tail-races like Codorus Ck, is not a good idea for those of us who prefer large trout or more large trout, assuming that the streams in question have big fish habitat and adequate forage for large fish.
Perhaps the decline in Logan Branch's once great large Brown Trout fishery was not or was not only a flow problem, but a cessation of stocking problem as well. Intense stocking of the 1970's and very high, unusual, long lasting angling pressure seemed to keep the populations of small and moderate size fish depressed by the time that summer rolled around. Large fish thrived with limited competition, unlimited forage, and their innate or learned abilities to make their capture difficult, despite the efforts of those who specifically targeted them with appropriate big fish techniques.
It has been observed by me in the past naturally low density wild trout population streams that are also spring stocked often seem to produce unusually large Brown trout for anglers in off-seasons, such as fall and winter.
