Is fishing hunting?

The title says it all– is fishing hunting? Or is it more like trapping? Maybe it's neither? 

I'm asking because, as a kid, fishing meant sitting on a dock in a lake, waiting for my Pokemon-looking fishing bobber to plunge underwear, signaling a bite. This sort of felt like I was waiting to trap my prey. 

But then, as an adult, I tried fly fishing. I was intentionally searching through a river, looking for fish, and casting my fly in very specific ways. This felt like hunting.  

Are there any philosophical opinions out there?
