If stocked fish can't survive in a catch and release steam, how do you explain a stream like Valley? It's not stocked still, although some tribs may be(?) and there is a healthy population that gets caught and does fine.
Or maybe the 20-25% that do survive are able to breed, and combined with similar numbers from additional stockings there is enough to eventually establish a population at which point stocking can cease?
Valley Creek's wild brown trout population was probably established before 1900.
Yes I understand it's nothing new. I don't understand why the same thing couldn't be done in a different stream today, like the author implies, without stocking it every year forever.
At one point it was stocked. A population was established. Stocking stopped years ago and we there are still fish there today.
If there was a stream that had the right conditions for wild trout, but no wild trout, a population could be introduced there.
This would be an extremely rare situation. In nearly all cases, if a stream has the right conditions for wild trout, they are already there.
Is such a stream was found, and you wanted to introduce a trout population, there would be no need for any hatchery to be involved.
You could just electrofish trout from a nearby stream, transport them by truck and put them in this stream.
You could do this ONCE, a one day operation. If the conditions are right the trout will reproduce and their numbers would rapidly expand and fill the habitat. You could close the stream to fishing for a few years. In about 3 to 4 years it would be swarming with fish.
But, does anyone know of such a stream? I don't. People seem to assume that streams are common. But I think they hardly exist at all. Because typically trout will get in there one way or the other, from either upstream or down. Trout move around a lot, including in what are considered warmwater streams, during the cool parts of the year.
