I can't say 100%, but I think I can be 99.9% sure Fishing skil has nothing to do with it under the new system.
Fishing has no bearing on anything in the game except fishing, it's an optional as is crafting. SE wouldn't make it so that you needed anything "optional" to get any of your AF.
However, before you do try to get your AF, go do some fishing and get used to the new system. You will still have to reel in the fish under the new system and trying to reel it in too soon and you will either break your line or the fishing rod. Both will loose you your bait.
