Hatchery Raise Trout

I was able to purchase a couple of hundred farm raised trout last year and placed them in my bass pond down here in SW Louisiana. It was mid January and the temps were suitable for the trout and also for the caddis hatch in progress.Although the guy from the hatchery told me that these trout had only ever been fed trout pellets , these trout took immedately to the natural food and were sipping caddis off the surface as fast as they could. Being a primarily warmwater fisherman , it took me a day or so to adapt my tying and presentation of the fly to fool these fish. After being caught and released though , these fish learned quickly and were increasingly harder to fool.
It was great fun and an awesome learning experience that I hope I have the fortune to do again.

Once they get it that no one is feeding them any longer most trout will start to look for food. They have no clue what to eat, and will hit most anything drifting in the current. I have found pine needles, bark, leaves, in trout. Many stocked trout will die before they really figure out what is food.
After a month or two, those that are left will have figured out that insects are good to eat. By the next spring, the stockers will be looking for hatching nymphs.
By this time of year, most of the insect hatching activity is pretty much over. Blue wing olives, midges, and some small caddis will still be about. Up until the first hard freezes, there will be hoppers, ants and beetles around. Fish a hopper pattern with a very small nymph (pheasant tail,) as a dropper. Later in the year, try a brassie or other midge as the dropper.
By next spring, you should research just what insects are common in your area, and in what order they hatch. The actual time of the hatches will vary with weather conditions, but the order will remain the same.

How about sharing your references for your statements for the benefit of the rest of us? It may be a geographical thing, but those stocked by the state here in our Texas waters will feed immediately upon release. And, no, they aren't looking for trout chow!

I have fished stocked ponds with my fish food pellet fly over the years, and it will work. I can't say the trout take it for bagged trout food, but it sure looks like the stuff. The trout in these ponds were fed the same stuff, and readily took the fly.

As originally noted, it may be a geographical thing. Also, those you base your observations on may be stunned, which you admit to, for that long by the "hosing out of the tank truck" Here, they are hauled in trailers pulled by pickup trucks. The trailer is backed up to the edge of the water such that the back of the trailer is slanted down, like on a boat ramp, the drain is opened and they simply flow out. No hosing of any kind. Not having been fed for as many as two days, they are rearing to go, right out of the trailer.
I too have PFC (Purina Fish Chow) flies in my boxes, but use them only for wipers (Striper X White Bass hybrids) and extra large bluegill (to 2lbs) in waters managed for these two species. I can even generate my own "feeding frenzy" with these flies, instead of throwing a handfull of the feed on the water, as so many do.

Florida , Texas, Louisiana, where at?...the study that is. Not that it matters to me up here in Nova Scotia, but I am a Florida boy at heart and miss me Reds and Trout and Snook!

They were caught in a power plant supplemental cooling pond adjacent to Trinity Bay, a sub-Bay of the Galveston Bay complex on the upper Texas Coast, just east of Houston. The objective was to determine whether or not the fish left the pond in the fall to join the Gulf adult spawning population; or if they stayed in the pond. The tagging was done in conjunction with our Coastal Fisheries folks. And yes, the sub-adults do leave the pond and go to the Gulf where they enter the spawning pool. We had tag returns from fish caught along the Gulf shoreline at Galveston, which is their normal spawning area.

In a small put and take stream I used to fish while in college in Kentucky, the summer season would see a bi-weekly stocking of pan-sized rainbows, dumped off the bridge into a deep pool. During the summer anything and everything would catch these fish, it was kind of neat to watch a half dozen fish fight over someone's powerbait (without the guy even realizing it, but I could see it from my point of view). Once fall came around and the stocking ended, the bait fishermen would leave, and it became a C&R stretch until next spring. The fish would disperse and they were as selective and paranoid as any wild fish.
I agree with most others in saying that in my experience, it doesn't take long at all for newly stocked fish to begin feeding, sometimes immediately. But just because they are naive hatchery trout doesn't mean they're "dumb" and will quickly learn what they can eat and what they can't.
It's kind of like a spoiled indoor cat that suddenly finds itself tossed outside. It may spend the first week meowing at the door, wondering where the kitty chow went. After a while instincts kick in and it starts finding and killing what it was meant to naturally. That's also the reason an indoor cat will chase a piece of yarn or bug that has entered the house, even though it looks nothing like a bowl of cat chow.
Wait a minute, this is a fly tying forum, why am I talking about cats??? I think there was a point in there somewhere....
Oh yes......Trout as predators probably have that same instinctual drive and curiosity that makes them eat natural food sources that they've never seen before.
This is just a thought, but I wonder if it is harder or takes longer for hatchery trout to adjust if they are placed in a stream where the primary food source is small insects such as midges and baetis, vs. a stream with large bugs like stones and drakes. Maybe it takes longer for them to develop a search pattern when there is a big difference in the naturals compared to what they're used to eating? Any thoughts or experience with this?

As far as eating, its instinctual, and they should eat immediately if not too stressed. As far as a fly, they probably have seen most of the type of insects already and will also take pellets for a short while. But they will quickly learn if it doesn't smell like a pellet it isn't a pellet.
