Is this the same fish?

So I just started fishing again, haven’t since childhood. I’m trying for predators since that is what I’d uses to do with my father.

Now I caught a small pike last week. A week later on Sunday I went out and caught a pike again, not exactly the same spot but the same water not to far away. They seem pretty similar I think maybe they are the same fish. It feels a bit awkward, like it’s wrong to just go out on Sunday and fish your regular out of the water.
