In one of the emails i received from the WGFD they talked about stocking 140000 koke fry below fontanelle dam. The first thing that popped into my head was "how many will live?" There are a lot of big fish in the river from the dam down to the gorge.. The idea of stocking them there, WGFD says, is to have them swim down to the gorge and then when its time to spawn swim back up and spawn so they can do an egg take. well, yes, the fish will spawn where they were stocked (most of them) but that's a lot of obstetricals to over come for a fry. i think ill go see how fat the trout are getting from the fry!
For some species stocking as fry is the only viable option as the fish don't feed well on conventional fish food. Consequently it can be prohibitively expensive or impossible to raise them beyond fry in a hatchery setting.
As to having them swim back to the hatchery so eggs can be easily collected, this is a common practice for salmon species.
As to whether or not these are "best" I don't know. From my view protecting a "natural" spawn where it can exist is best, but that's not possible for many species we angler demand in our fisheries that are not native and have very specific requirements to successfully reproduce which are frequently lacking in waters they are stocked.

I wish more states would protect spawn for all species, especially on waters where maintaining the fish populations is possible through natural reproduction. I personally feel that's a better option for the fishery, although that approach doesn't always mesh with angler's desires.

The waters from Roaring Judy is spring water, that is what the fry return to, everything from perch to lake trout eat them and a few feathered friends, the more spawn they get the happier the fisherman will be.
