Achivement "Bigger fish to fry"

[SpYr0]

WoW Freakz link:
Bug description: achivement
Proof: dont have one because items required dont show
the achivement that i want is "Bigger fish to fry"
it gives a ton of quest items but not the ones that you need for achivement for example i wached youtube for "Ancient Black Barracuda" location and went there fished for more than 2 h and nothing from time to time it gave me like an empty item box to colect witch contains nothing, i thought that is supost to be the fish i needed for chivement but there is nothing there, and that is not the only one .... got a few items that are requiered for it but im missing alot and i think i fished allmost 1 whole day for it.

P.S i have seen someone reported it and no players have done this achivement, take it as a friendly reminder
A Big THANKS in advance for fixing it , have a good day
