Yeah but none of the fish are really there, like the chickens and other animals. I think their just an animation. Fishing would've been cool and would've helped set it apart from the other open-world RPG's. You know, aside from the mind-reading and dragon-morph stuff.
Also, I just came up with a weird little story for the skeleton. You know how Calvin at the top of Lovis' Tower said his friend 'died' when he started thinking about being a living skeleton too much? Well maybe he was fishing when it happened. Your mind tends to wander when your doing something like fishing. So he started thinking too much and killed himself.
