Bait aside, there is a method to the madness of fishing.
Start off selecting depth and wait.
If you get nothing, select depth again and wait,
else you can select to wait or jig. Wait does nothing that I can think of, so select jig.
At this point, I like to double tap on jig so I get perfectly in the center of the half circle gauge. If you hook the fish, it will remove some of your energy and give you a message. If not, you simple don't get the fish.
Generally speaking, if you do the double tap method you will either catch the fish or get a "you have a fish on the line but can't real it in" message. To catch a fish if you don't auto catch it, simply fish at about halfway down the semi circle to the left first. If you get the sparkle, you hit that same spot again and you will catch the fish.
If not, check out what it says. Usually it'll say the fish is taking line, which means you need to set the hook half way down the RIGHT side of the half circle this time. About half way down on the right side will do.
You will catch a fish / run out of energy but know what fish you almost caught 90% of the time with this method. The most this method has ever taken for me to catch a fish is actually 4 tries. Sometimes you only get 3 guesses, but with 4 guesses you can catch fish nearly 100% of the time.
I made a video showing my method. Will upload it to youtube later.
That's interesting method. However, I noticed that the chances of hooking the fish in the first jig is small; it usually takes 3 jigs in the "correct" direction to get the fish tired enough to be fished up. I noticed that if you jig in the "incorrect" direction, your remainder bar decreases really fast.
In other words, doing the double tapping, you start at the center, and then you would have 50/50 chance of getting it "correct" no matter which way you jig after the first jig.
So, my method is:
1st jig: jig at almost to the very end of either side of your choice (I usually choose the right side since it goes to the right first). 7/10 you will get, "you have hooked something, but you cannot reel it in."
2nd jig: pretty much to the middle, and it will definitely be the "correct" direction for the jig, so you will have the 4 things happening
1)fish is tired, but you cannot reel in (in this case, jig at the same spot, you can usually fish it up)
2)you take in some(or great deal of) line (meaning you jig in the "correct" direction, keep going)
3)the fish got away (2-3 kind of different message to mean about the same thing)
4)you reel in your fish
chances are that you get message #2
3rd jig: since the game will not treat you so well to let you reel in fish that easily, you will usually need to jig again. since on the second jig, you usually get the "you take in some (or great deal of) line, it means you just need to keep going with the jig direction. and you can usually fish up by 3rd jig.
in this method, you will actually never jig in the "wrong" direction which usually causes a big remainder loss.
this is just the way i do it, doesn't mean it's correct in any sense.
