Fish It Mutations Guide

In Roblox Fish It, catching a Great White Shark will make you look cool. But what about catching a Neon Radioactive Great White Shark? This will make you a legend and a billionaire. To achieve this target, you will have to learn about Mutations. They are rare modifiers or skins that are randomly applied to the fish when you catch it. Mutations don’t just change the fish’s look; they increase its weight and selling price.

That is why knowing how Mutations work in Fish It highly important. Or else you will be stuck in a forever loop of catching and selling fish. Without knowing that some very rare catches can turn you into a billionaire in one night.

Luck vs. Mutation Chance (The Golden Rule)

Everyone must know about the difference between Luck and Mutation before they start fishing. If you do not understand this vital difference, you may waste your bait.

  • Luck: Increases the chance of finding a Rare Species.
  • Mutation Chance: Increase the chance of fish having Special Skin.

So, in simpler terms, if you want to fill your index to the full, then stack Mutation Chance instead of Luck. High Luck will help you to get Rare Fish, but it will take a longer time to catch. And you get fewer dice rolls per minute.

Mutation Tier List

Here are approx values of all Mutations you will find in the Roblox Fish It game. The values are subject to game patches.

Mutation Rarity Sell Price Multiplier Effect
Big / Huge Common 1.2x – 1.5x The fish is physically larger/heavier.
Shiny Uncommon 4x Has a sparkle effect and lighter texture.
Electric Rare 6x Surrounded by small yellow sparks.

There are some Event-Specific mutations like Frozen. It occurs during Christmas. Similarly, Pumpkin appears during Halloween. These are Epic-Tier mutations, so do participate in events and do not miss the chance to grab them.

How to farm Mutations?

There are two ways you can farm Mutations faster in the Fish It game. First can be done on Fisherman Island, and the second is through an Event.

Fisherman Island Mutation Farming:

  • Equip a Fast Rod with Mutation Hunter or Cursed. A Carbon or Steel Rod will also work.
  • Now use Worm Bait for Speed. You can also use Dark Matter for Chance.

Fishing with this build will give you a starter fish every 3 seconds. So you have 20 chances per minute. This is much faster than fishing in the deep ocean, where one fish takes around 30 seconds.

Nuclear Event:

Always pay attention to the weather. There is your second chance of farming mutations. Look for a Radioactive or Nuclear Storm event. The global mutation rate at this time increases drastically. Drop all your tasks, just keep fishing until the event is over. Fishing at this time is much more rewards than in regular weather.

If you are lucky, you might get a Mythical Mutation. Which is much more valuable than any regular catch. For example, if you catch a normal Karken and sell it, you will get 50,000 Coins. But if you sell a Rainbow Kraken, you will get 2.5 million coins. Also, do not forget to take a screenshot before selling a Mythical Mutation. They are so rare that it’s considered a trophy in the community.

FAQ

Can I breed fish to make them mutated?

No, mutations are determined the exact moment the fish bites your hook. You cannot change a normal fish into a mutated one later.

Does the “Big” mutation stack with others?

Yes! You can catch a “Big Gold Shark”. The multipliers stack, making it worth even more money.

I have 100% Mutation Chance but still catch normal fish. Why?

The stats in Fish It are usually multipliers of the Base Chance. If the base chance for a mutation is 1%, having “+100% Mutation Chance” just moves you to 2%, not 100%.
