How The Harpoon a Fish Farm Works

Auto Dive sends you down to the zone set in Stop At Zone, and Auto Harpoon catches the fish on the way, filtered by the Rarity Filter if you only want the good ones. Once your bag reaches the Return When Bag At number, you head back up and the next dive starts.

Back on your island, the Aquarium tab takes over. Auto Equip Best keeps your top fish displayed, Auto Feed Fish and Auto Grow Equipped Fish raise their income, and Auto Upgrade Aquarium adds slots. The Base tab opens crates and claims free gifts and Index rewards along the way.

Harpoon a Fish Script FAQ

Is the Harpoon a Fish script keyless?

Yes. The Ouroboros loader has no key system, shortlink or whitelist. Paste the loadstring, execute it, and the menu opens.

How deep does Auto Dive go?

As deep as the Stop At Zone setting. Max Depth goes all the way down, where the legendary fish are, and Return When Bag At decides when you come back up.
