Can anyone identify this fish?

Looks like a carp. But it’s by a canal that feeds into the sea, few hundred yards from sea. Also has blue crabs around it

I’m not sure what kind of catfish this is. I am thinking a channel cat, but have never seen one this big.

What in Gods name did I catch?

No black tips to the dorsal fin so i’m not sure if it’s a blue runner

Caught in Lake Billy Chinook, Oregon. Thought it was a Kokanee at first but the black spots and dark mouth are throwing me off.

Columbia River @ Revelstoke

I recently made the discovery that my stream, connected to my garden, now had a small family of fish in it. It's odd because the stream is usually very shallow and very small, so the only "real" native species that houses here are crawfish. Idk if these are kois or something else. Can someone help me? If those are kois then I know these are not natural cause in the rivers where I live, kois are not natural.

The stream is a part of the bigger river 'Wupper' in western Germany, in the "Bergisches Land"

Southern Wisconsin, where the marshland meets a lake

I think it’s another bottom feeder fish. Was fishing near a marina near the beach. This is the same NLBN I used to catch the lizardfish. If anyone had any idea what this is let me know it kinda looks poisonous.

So let me start by saying Im a very scientificly grounded fisherman, and am well aware that bluegill and crapi almost never hybridize in the wild; however, this bluegills patterning and coloring above the vertical line is almost identical to a crappi, and also has that purple blue glint in person, as well as the baring of a white crappi. This particular pond has copious amounts of LARGE crappi and bluegill in it. The picture also dosent illustrate this, but it’s particularlly stretched out and long for a bluegill, and its mouth is almost more similar to a green sunfish in terms of how much it opens.
