Stocked Trout Movement

[Nomad]

Thought this was interesting, never had seen a study like this before.

Appears that most trout don't stick around to long where they are stocked.  Things like good water depth, structure, temperature, help to make some stay.

Rainbows stay at their stocking location the shortest time.  3 days and then may head many miles downstream.  One was found 126 miles away.

Browns stay for about 7 days.

Brooks stay for about 10 days.

Really? I've read studies that show exact opposite. That rainbows don't move far at all. So many factors could change study results though I guess.

I believe I have heard that stocked trout always move downstream.

I guess it's all about food. If it's good, they will stick around. If not they go hunting.

That would imply that most rainbows stocked in Flatbrook end up in the Delaware river

After all this rain we have had they probably are! Lol

 I read an article that longevity of stocked trou here is under 132 days before eaten, caught, etc

That's over 4 months. Sounds reasonable.

My Friend is an avid Trout Fisherman. He only fishes the Manasquan River. He has caught trout every month of the year when weather allowed it.

thats a cool study, thank you so much for sharing.

Ross Shramko, Principal Fisheries Biologist for the Division did a similar study on rainbows in the Flatbrook and found the same results. Most are caught by anglers and predators fairly quickly. Very, very few stocked trout survive a year or longer without being fed at least sometimes and without good, deep pool habitat.

What predators catch trout in the streams and rivers other than eagles and Nomad ?

Was told that stocked rainbows ran downstream. Held true on the Pequest. Back in the day, when it was the weeks when they were stocked, I started 50-60 yards downstream from the bridge.  Brooks seemed to stay put in the bridge pool or under the bridge with browns spread out just up and downstream. That held true for the three places I fished.

That is study I was referring to.
