Chena River, Fairbanks Alaska. A swimming beast is caught on tape. What is it?

Saw this on the news last night (here in Anchorage).

It looks really neat! And calling it a "sea monster" or even a "giant fish" is a stretch. In the end, debris floating in the river being moved by the currents.

Been down the Chena in a canoe back in the day. Occasional salmon in the deep parts and a grayling or two. Nothing that big. Now if it was hanging out near the electric company near the warm spot that would be another thing.

It is not a "fake" video. It is a real video. But not of a cryptid.

don't really think it is any kind of debris, or anything man made or a hoax.

for the simple fact that if you look you can see some sort of appendage be it a fin or leg break and cause swirls in the water near what i would say is the head a couple of times and you can just see it below the suface a couple of time when it does it.

plus the movement matches what you see other types of fish, or water creatures have.

With the inclusion of the ominous music the only thing missing is our Jeremy:

one of my favorite shows to watch.
i bet he already seen it and making plans to figure it out.

I started the thread, but don't always go on my computer and for the last year I haven't been able to log in to ATS on my phone. I can be slow to respond at times. I am pretty sure this is a Sturgeon. It was kind of cool and I just wanted to post it.
