The thing that always amazes me about brown trout in lakes and reservoirs is some fish outlive and out grow rainbows in the same body of water.

Mice, voles, small birds, and probably every baitfish imaginable. Nice fish!

A guy I follow on YouTube fishes that river, and he has some videos of stupid big browns under his dock. He says the giant one eats the guts/carcasses that get tossed from cleaning fish.
I’d suspect whatever this guy was eating he wasn’t expending much energy to cause it down. If I remember correctly the big ones are Triploids also. Assuming this one is a triploid as well, but I don’t see it mentioned anywhere?

Missouri Dept Conservation says it is a triploid. As far as carcasses I have heard of browns and steelhead feeding on the carcasses of dead king salmon.
I still say fish like this forage on newly stocked 8 to 10 inch trout. I remember reading in Outdoor life years ago about big browns nailing smaller trout as they were dumped in by a stocking truck at Pepacton reservoir. This was in the late 60's early 70's. The smaller newly stocked trout were clueless and easily picked off.

Pretty neat video of said fish. I’m surprised it didn’t make it, you can tell those guys know what they’re doing and did a great job trying to get the fish back swimming.
-
why is it a surprise it didn't make it? said it was caught on 3# line. that means it was fought to death when caught. they must have been gill fishing or something, and caught it on accident? smoke that sucker up!
Did you watch the video?

Not trying to be negative but I didn't see much for aeration in the first tank. Also looked like they then dumped it into well water, which may have been at least 10 degrees colder than the original water and low in oxygen. A 10 degree change or more can cause a fish to go into shock. With my experience handling trout, I would have used salt and an ammonia remover with plenty of aeration. Not sure if they did. Salt makes a BIG difference when a fish is stressed. That said, it's an old fish (8 to 9 years old) (Make your 90 year old grandpa run even one wind sprint and see what happens.)
Additonally Missouri Fish & Game said this about catching trout this time of year in the reservoir:
"Due to low dissolved oxygen conditions present in Lake Taneycomo in the fall, anglers should attempt to minimize the time that they fight and handle fish caught below the dam to ensure the health of the fish."
That said this fish was near the end of it's life span. I commend the anglers with trying to revive it but not all fish survive hook and line no matter what you do. And being a triploid it was sterile.

@taxid
Yeah agree with most of what you said. Looks like they are pulling the water from the lake/river for the upper tank, but could be a well too. You know way more about this stuff than most of us, and I appreciate your input as always.
I also agree they should be commended for trying to keep it swimming. You could tell they were concerned for the fishes well being which is what I enjoyed.
Also if you check out some of the older videos he has, the previous state record brown from earlier this year was assessed at the same place, and that one did swim away. You’re probably right about the low O2 in the river/lake being an issue.
I’m still blown away by the fishery they have down there. I’d never think to travel that far south for excellent trout fishing!
-
Old fish too. Id have to imagine its tolerance for such activities decreases with age.

Zwiggles.
Doesn't matter how fast south you are if you pull water out of the bottom of a reservoir (tail race). That said the White River and Red River are pretty amazing down there. I just wish my state would manage the few natural lakes we have for large trout instead of put and take, and allow us to reestablish smelt as a forage fish.
-
FWIW I used to work at an Atlantic Salmon broodstock hatchery. We had one big male which was 50 lbs in a 20 foot circular tank with other "smaller" salmon. Every Friday when we would clean the tank and draw the water down, the fish would get winded and lay on the bottom of the tank. He would right himself after an hour. Once he never got back up.
Think of this fish like an obese person who doesn't exercise trying to climb Mount Everest without oxygen.

Agreed on bath parts. Even if only a quarter of the lakes were managed as cold water fisheries I think we would be happy.

Why wasn't the circular tank self cleaning? All my circular tank systems I built are self cleaning.

It was....for solids...but a biofilm would collect on the surface(it was a plastic liner). If you didn't get in the tank and scrub the bottom every week, you could fall on your butt, it would get so slippery. We did all our spawning/sorting inside the tank, it was easier than lifting 15 to 30 lb salmon out of the tank.
We had a system, get in the tank, scrub one spot so you could stand up, then cycle through the whole floor, get out and pull the outside sump plug to partially drain the tank.
-
Interesting. I've never had issues with biofilm. And I find draining tanks with fish in them, moving fish etc., is a stressor I try to avoid.
I'm going to hatch the trout in an RAS raceway this winter vs. the floating baskets. The baskets collect debris and clog. I think I may have had some gill issues witnessed by some short gill covers. Probably irritation from suspended particles in the baskets. I'm hoping with a raceway I can screen off the fish periodically and clean and flush any debris out. May move them to the circular tank once they get to be a certain size though.
-
If it is a raceway have you looked into baffles?
That is pretty much what my new boss wants to do with our raceways instead of cleaning by scrubbing, drawing down, etc.
I prefer a non fish zone at the back of each rearing area for settling solids. We actually have solid baffles hanging over our end screens inside where only maybe an inch of screen is exposed so the force pushes solids better. You can drain the sump without having the whole tank drain. The only problem it can pin fish quickly if they are small.

I'm looking into all options. Keep in mind this raceway will be small only about 6 or 8 feet long and a couple feet in diameter. I don't hatch many eggs compared to a typical trout farm. One of the issues I also had with the circular tank was, it was quite deep (I've seen redone it to adjust the depth) and then the silly fry would drop to the bottom and be too far down to accurately feed. Fine for when they reach about 4 inches or so but smaller I had issues.
Was going to order a fiberglass trough tank and was all excited as the company AES/Pentair had free shipping if an order was over $50.00. Well of course when I was ready to order they discontinued that. So I will be building one out of plywood and coating it as shipping is more than the tank!

We just bought some 250 gallon 5 foot circulars from Pentair to use as start tanks...they're pretty deep and a long reach to the other side. We normally use 12 foot long fiberglass tanks that are 20" wide and 6" to 8" deep to start fry. From there they go to 20 foot raceways that are 3 feet wide by 2 feet deep. We do use baffles in those we made out of black sheet plastic that is flexible.
Once we made mini circulars out of 15 gallon muck buckets. They worked well for starting fry and had steelhead in them for a year, about 20 to 25 fish per tank 4" to 7". We made a drain in the middle with a PVC shower drain which connected to a stand pipe outside the tank which we could unscrew(threaded PVC), it also had a smaller valve off the bottom for slow draining. We would run maybe a gallon or two through the tanks.
