Players can now fish for energy in Treasure Isle, and each fish represents different amounts of energy that you can earn. At a glance, this sounds awesome, since energy is something players are always short on, but here comes the bad news -- in order to fish, you need the following:
Be at Level 7.
Spend 3,500 Coins for the Strong Fishing Pole.
12 Energy for each time you fish.
Pay between 625 Coins to 25 Island Cash for batches of fishing bait.
