Videos have shown bomb fishing and catching fishes with the bare hands. I'd be surprised if you can't buy or construct a fishing rod as well.
It's kind of a tradition in modern Zelda games; so I hope that there will be a fishing rod in BotW!
In addition, you can probably use it as a weapon and to distract enemies - like you could in Twilight Princess.
I always called him Link anyway, when you have such a well-known character with a well-defined name, calling him anything else feels weird. I'm not playing as the blank-slate nobody you start out as in most RPGs.
I can see why people would be upset though, as naming your Link is probably a tradition for most.
When I was very little playing the original The Legend Of Zelda, I used my real name - but shortly after that I always named him Link, because that was the name Nintendo wanted him to be called.
I didn't realize this at first but the final strike of each weapon class' basic attack will each knockback the enemy in a particular direction. Backwards for the spear, left for 2 handed weapons and right for one handed weapons. In addition AoE attacks tend to bounce enemies into the air so there's a subtle layer of depth with how the physics are applied to combat if you want to knock an enemy into a particular direction.
