Sadly Mischief has come out and said this quest will not change. The fish will change to Yellow Snook so it is not confusing on the name but the size will still be the same.

I agree! I play several hours daily & have no problem completing the other quest but the Huge Large Trout is impossible for me. I caught one months ago but that doesn’t count on the weekly quest. I have never caught another one therefore that quest goes unfinished. It was given 2 weeks in a row but I couldn’t catch one HUGE LARGE TROUT no matter how many hours I played.

Thanks for leaving your feedback Zedlyn, we'll look into making some changes to make it clearer in the future.
