how long does it take a stocked rainbow to become naturalised to life in a lake.
how long before they start to feed //take a fly?
do they spook easy when introduced due to noise and other natural things like a duck/swan /boat /cormorant landing on the water.
If so would the resident trout in lake also spook.
what would be the best fly/lure ect to try and tempt them with.

Some stockies never aclimatise and fade away. Perhaps as high as a fifth.
Some will take a fly instantly, but that is not the same as feeding.
best fly a BLOB

The feeding and stocking level in the pond would be a big factor.
I would also consider a rainbow naturalised when they stop taking anything flung at them and when you need to match a hatch to target the fish.

LOL,
Thats cause reality hit home!
Stockies will take anything from the second they are introduced!
just has to attract them, or look like food!
After a short while they will focus on the natural food sources like bloodworm, buzzers, olives et al. but they will still nail anything that attracts them to take.
Can only be classed as "naturalised" after several winters in same water, by that time they have keyed into the food cycles of the water they are in.
put and take fisheries are exactly that.
100 get caught, 100 go in.
Is only on c/r only waters that stockies could ever become "naturalised", and even then they aint!

Interesting. I would agree with Bert, but two factors are very important :
stocking density and angling pressure. In overstocked lakes the natural food content will never sustain the population and fish will display feeding habits based on competition. In over-fished lakes fish will wise up quicker and a number of stressed fish will even stop feeding on natural food. So the key to induce natural behaviour is a moderate stocking policy, adequate natural food stocks and reduced angling pressure.

Regards,
Johan

begs the question what is 'naturalised' a wild brown trout apparently can reach 8 or so years from the egg, learning to survive all the way, can a stocked fish ever catch up?

IMO never, unless he's never fished for and has the same habitat, population density and food supplies the wildie has.

Talking to someone last week at my club water and they reckon it could take stocked fish 6 months to aclimatise and they will also stay as a group for a while. The fish will also be still switched on to pellets and in some cases, regular feeding times.

wow that worked
