Trout Movement study

[Almaink]

I wish they would do a study like this in the D&R Canal so we would finally know for sure what happens to the trout after the last stocking when the water gets to warm to support them. F&G biologists have told me "they will seek cooler water" but my question remains as to were this cool water is.

Neat, It's probably best to focus on the parts where the fish are surviving and reproducing first. It would be neat to see how stocked fish in waters like the canal do when it warms up. Most likely they die? But would be neat if they recorded one surviving

I give trout a lot more credit than most in moving water, not so much in duck ponds.

I think some find the deep holes in "put and take" rivers such as the Rockaway, Passaic and Ramapo and places like the D&R canal, to sit out the summer. I'm curious about the percentage. I suspect it is fairly small.

As a species rainbow trout are the more tolerant of warm water than brook trout. I'm sure if they get enough oxygen in the water the trout can survive in places like the d/r canal. I'm sure there has got to be some springs and feeder creeks that will provide suitable condtions.

Some will find seeps or even heavily shaded inflows that have lower temps. I used to keep two brookies in the creek in my backyard. Topwater drainage of a duckpond went underground for a 1/4 mile and stayed cool enough for trout to survive in one bathtub sized pool. Even 10 feet away from the drain entrance was too warm.
