I don't know if this is actually glitched, but I can't get it to unlock for the life of me. The achievement is "Bookworm." See description below in Free Fishing Mode Achievements.
All of the achievements for this game are simple and straight forward. It just takes a little bit of work to get some of them. There are only two achievements that I would say that are "hard." I have pointed them out in the guide below. (marked with a *)
I played the game with a regular controller. I am guessing from the game mechanics that a regular controller makes it easier than using the "fishing pole." I guess waving a stick around your living room could be fun though.

Find a fishing spot (green/yellow dot) and cast on the outskirts of the spot. Just be sure that when you cast your aiming circle is not green. You will still attract the fish from that spot, but won't get credit for casting into it.

Quick Catch - 30 points
Catch a fish of any species in under 1 minute from the start of any event in Tournament mode
Look for the closest hot air balloon. As long as you got the correct lure on you should have no problem on this one. Is easier on the Crappie tournaments because they are usually around 1 or 2 pounds.
Confident? - 15 points
Weigh in early during a Tournament mode event
Just get back to the main dock before the initial time runs out.
Is That Who I Think It is? - 10 points *
In Tournament Mode, begin fishing alongside each competitor on the lake while they are fishing
This is one of the tricky ones. You have to start fishing beside each competitor of the tournament. It is hard to keep track of them all, but it can be done. Start a Rookie Tournament Event (they have the most time) and just concentrate on finding all of the other people. All you need to do is cast while beside them. You do not have to actually catch a fish.
False Hope - 30 points
Catch 5 fish during any tournament event Weigh In interval of time
Weigh In time starts after the initial clock runs out. You get ten minutes to do this in. Do it on a small fish tournament, Crappie or Small Mouth Bass.
Like a Sturgeon - 20 points *
Finish the Sturgeon Legends event in top 5 using only the 10 lbs. (4.5 Kg) fishing line
Good Luck. This is the hardest achievement in my opinion. This is a Professional Tournament and these things are 35 - 40 pounds at the smallest. Just take your time and keep the fish off the edges of the screen and you will eventually get it.

You get this technique during the Rookie season. It works on fish that are less than 6 pounds. When the camera changes to "out of water" keep the fish centered and you will see the gauge start to grow. Click the left thumbstick when it says to. It will turn off once the fish hits 4 feet.
