Hey! the vision for the fishman island is true but it will take place at the last part.

One Piece is all about combining the grand line and the new world. So, luffy must destroy the reverse mountain and must destroy the fishman island, it explains the vision for fishman island. To do that luffy will get the ancient weapon to destroy that mariejoa/fishman island.
