Just caught in open water in Valgarde on the rocks next to dock. Did open water casts and when pools appeared i fished them otherwise I didn't move. Tried doing pools only to much travel so gave that up for the not leaving till i have it method. Here are my numbers. By far one of the harder to catch fish for me was like all my luck had run out big time! The Rat was probably my next hardest see stats below for more info:
Bonescale Snapper 1710 - 42.2 %
Fangtooth Herring 1302 - 32.1 %
Glacial Salmon 593 - 14.6 %
Pygmy Suckerfish 295 - 7.3 %
Reinforced Crate 85 - 2.1 %
Crystallized Water 64 - 1.6 %
Dark Herring 1 - 0.0 %
Since I'm already "Salty I figured i had to have some of the tough to get fish. I caught the Steelscale Crushfish and Rockhide Strongfish already before the patch and couldn't use a mace so I had to get the Dark Herring to go with the others. I had the 15 pound mud snapper for the one that didn't get away achievement.
