Quick Answer

Follow the scientist’s requests, use the correct whale bait, defeat the Whale, carry it to the volcano, then prepare for the Mutated Bowhead Whale sequence.

Before you start

This guide answers “how to beat mutated bowhead whale in how to fish” for players who want a direct in-game route, not a generic real-world fishing answer.

Check the active NPC request and your current island before spending money; progression is usually tied to a trigger or hand-in.

Use this route in your run

Work through the steps in order and pause when the stated requirement is not met. The next obstacle normally becomes clear after the relevant quest item, boss trophy, or coordinates are received.

For a different type of problem—combat damage, money, a collection gap, or a co-op setup—use the related guides below instead of repeating the same farm.

What to do

  1. Follow the military scientist’s requested creature steps.
  2. Bring the assigned bait instead of throwing random catches into lava.
  3. Defeat the Whale and carry it to the volcano to advance the experiment.
  4. Use strong upgraded weapons for the Mutated Bowhead Whale and finish the military objective.

Important tips

  • The volcano step is an experiment requirement, not a general disposal mechanic.
  • An Assault Rifle and its upgrades are a sensible endgame goal.
