Definition: A holdover trout is a trout that is stocked and lives in a stream for over a year beyond the original stocking. I would go even further by saying it spawns at least once, but that isn't included in PFBC definition.
All of the surveys that are conducted show that stocked trout only holdover in very tightly defined circumstances. Since nature plays the biggest role in these conditions nature determines how many trout will holdover. Fins take years to grow back after the torment they are exposed to in the hatchery environment, even on wild fish you can count on fins taking a long time to grow back. I have personally witnessed this on a couple of surveys myself. Fins just don't grow back in a year or even 2 years even in the most fertile streams.
As for fingerlings, surveys show that about 1 in 1000 fish survives fingerling stockings, unless conditions are ideal, this is apparently the contributing factor in why fingerling stockings in the Tully were halted. It is also why no matter where fingerlings are stocked in such high numbers.
