if a stocked rainbow was to survive the fishing season any chance it might take on characteristics of a wild rainbow such as coloring red stripe red cheeks
,full tail not damaged etc.

While no expert on this I would say yes. If it survives a few seasons it would have to take on the characteristics of a "wild fish" in order to
survive. This would include feeding habits, finding appropriate lies and understanding thermal issues. I think it would include color blending to stream it
was living in. Again, no expert.

They sure do. I have seen it many times especially color at spawning time.

thanks for information on this i dont think they develop pink meat like a wild fish i am just guessing but i dont think a lot do survive to next season

I've caught fish that were tagged when they left the hatchery several seasons later. They had brilliant coloration, much more so than the current stockers.

Deepening of the color can happen within a few months time. It's a lot more of a problem for the fish with worn fins to fully regenerate them. It depends
on how young they were when stocked, and how much fin wear they had. Holdovers may get partial success, but usually the fins don't fill out fully like wild
fish. And, of course, if they had an intentional fin notch or adipose fin clip, that doesn't grow back.
If the stockies are eating a lot of shrimp or crustaceans, they may eventually get pink flesh. |

30 plus years ago I sued to fish a Tailwater in Missouri called Taneycomo - the fish were stocked heavily in the fall and the shrimp population allowed them to
grow an inch a month and to take on the pink coloration. The fish were little footballs after about 6 months in the lake. a 16in fish weighing almost 2 lbs.
It was and till is a great fishery. The fish do grow back the fins and take on their natural coloration. In most streams the forage base is not enough to
support this kind of growth. Taney does not support it currently. I miss the fishery. Of course we do not have this problem in Montana as we stock few
fish.

Coloration is mostly a function of food source, and genetics of course. The same species (or strain of a specific species) of fish living in two adjacent
streams can have different coloration if the forage is different(scuds compared to bugs). Fins can grow back. We reguraly notch fins of fish for
mark-recapture studies to estimate population size and if you don't re-sample in a short time frame the fin will grow back to normal. Adipose fins
don't really ever grow back quite right, thus this fin is the one chosen for long term monitoring of some salmonids. Dorsal, caudal, pectoral, and anal
fins will often grow back to normal in a season or so. So to answer your question, yes, a stocked fish can take on the characteristics of a stream born fish
if it "learns" to act like a wild fish and makes it through a season, which from what I've seen isn't all that likely but definitely happens
from time to time.

Casey, I'll let you judge. Some Wisconny fish from a tiny creek with a hatchery just above it. I'm believing these escaped a few seasons prior... Jeremy.

We have a stream here in NC that has huge fish all through it and is directly below one of the state hatcheries. Plenty of good reproduction but the fish gorge on micro-pellets of left over feed from the hatchery effluent. Some folks even fish small brown flies to catch them. Just a thought. CWood |

As an expert by virtue of catching some holdover trout every year I can attest to the stockers taking on the color and physical characteristics of native fish,
including fighting ability.

From what I understand from my fisheries biologist sources, the dorsal never regenerates, nor do any fins clipped before stocking. Tails do seem to heal, and
given a good natural food source the fish's coloration will be all but indistinguishable from a wild trout's in a matter of months, maybe weeks.
