Question about the new Sea Turtle

Q u o t e:
I'm pretty sure the patch makes it so you can fish anywhere, regardless of skill level. Also the quest from Nat Pagle is no longer needed to skill up, but it gives you a fishing pole as a reward instead.

Players are now able to fish from anywhere regardless of skill level, however, the chance of catching useless junk in high level waters goes up astronomically for the under-skilled player.

Q u o t e:
so you get skill ups for fishing junk or is it just that junk?

You should still skill up, you just won't be catching much stuff that is useful. It'll be junk to be sold to a vendor.
