The open-world fishing simulator on Roblox, Fisch, has an impressive RNG feature that occasionally grants you unique variants of the regular fishes. This can be achieved passively using better fishing rods or manually by taking them to the Appraiser. This feature is called Mutations and can bump up the prices of the fish you catch. Want to know what exact benefits all mutations provide? Keep reading as we detail all Fisch mutations, their benefits, and how to get them all right here.
In Fisch, the mutations depend on the luck factor and would be visible on the fish you are reeling in. Certain mutations are applied only when using a dedicated rod, while others can be found during certain server events. These multipliers can increase or decrease your fish’s sale value according to its corresponding multiplier. With that said, here is a list of all Fisch mutations in the game.
Editor’s note: We updated the list of Fisch mutations on November 4, 2025.

While the first could be obtained during the Pharaoh’s Curse, the second one, when the player is wearing female accessories, and the third one could be obtained only through codes.
List of All Fisch Attributes
Although you cannot have multiple mutations on a single fish, you can definitely have a few attributes stacked upon a particular mutation. Attributes in Fisch are of four types, which are as follows:
| Attribute Name | Value Bonus | How to Get |
|---|---|---|
| Shiny | 1.85x | 1% chance in regular days and increases during Shiny Surge event. Better found using Blessed enchantment and the Destiny Rod |
| Sparkling | 1.85x | 1% chance in regular days and increases during Night of the Luminous event. Better found using Blessed enchantment and the Destiny Rod |
| Big | 1-1.99x | Can be applied to fish during appraisal. Better found using Sea Overlord, Sea King, Abyssal, Noir Enchantments, and King’s Rod, Poseidon’s Rod, or Season’s Rod |
| Giant | 1.99+x | Can be applied to fish during appraisal. Better found using Sea Overlord, Sea King, Abyssal, Noir Enchantments, and King’s Rod, Poseidon’s Rod, or Season’s Rod |
The best thing about the attributes is that you can get them while appraising and won’t lose them, except for the big and giant fishes. The latter two can be removed if the fish’s weight is depressed enough.
How to Get Mutations in Fisch
Besides the methods, there are a few more ways you can get mutations. These are:
1. Appraiser and Chiseler NPCs
Now you know that you can easily get the above mutations due to the passive ability of a few rods. However, there’s another way to get them manually through two NPCs. You’ll find an Appraiser NPC beside the Merchant at Moosewood (445, 150, 210).
If you bring your fish or any item and interact with the NPC asking them to appraise its value, they will do so for just 30% of the current fish’s sell value in C$. However, this price can be reduced to 22.5% if you have the Appraiser’s Luck game pass.
Appraising a fish or any item can increase or decrease its weight or apply a random mutation to it. The rate of having a mutation applied to the fish is very low on a normal day. So, waiting for the Mutation Surge event is recommended since it will increase the rate of mutated fish by 15%.
Apart from the Appraiser, you have another such NPC, known as the Chiseler, at Ancient Isles. This NPC will chip all your Amber fishes and give them either a Purified or a Revitalized mutation. The Chiseler will ask for just 100 cash to do this job. It is further reduced to just 75 cash if you have the Appraiser’s Luck game pass.
2. Weather-Based Events
As mentioned above, the Mutation Surge event increases the chance of getting mutated fishes by 15%. However, it’s worth noting that a few other events also enhance your odds of getting mutated fishes. These are:
- Starfall: 5% chance to get the Nova mutation
- Rainbow: 15% chance to get the Mythical mutation, 5% chance to get the Rainbow Cluster mutation, and an increased 5% chance to get Shiny and Sparkling attributes
- Eclipse: 10% chance to get the Solarblaze mutation
- Shiny Surge event, which increases your chances of catching Shiny fish by 3%
- Night of the Luminous event, which increases your chances of getting sparkling fish by 10%
- Moonlight Mirage event, which increases the chances of getting the Lunar mutation
Apart from these, you can also check our weather events guide to get an idea of all the admin-exclusive mutations available in Fisch.
3. Treasure Chests and Baits
Finally, you can fix treasure maps you get from fishing and unlock treasure chests in your world to find fish with the Sunken mutation. Moreover, various Fisch baits, including Aurora Baits and Chocolate fish, allow you to obtain fish with the respective mutations.
Since these baits are event-specific and are currently unobtainable from crates, you might think of using a Scrapper Fisch enchant on your rod, as it reduces bait consumption by 60%. Finally, you can also consider redeeming the latest Fisch codes to get some baits for free.
And now you know about all Fisch mutations and how to get them. Which one do you feel is the easiest to get into the game and also provides the best value? Let us know in the comments below!
Chaotic mutation (12x value) is currently the best mutation in Fisch. However, the chances of getting it are 8% and only using the Chaotic Enchantment. Prismize mutation is also a good option with a value multiplier of 8x; the chances of getting this are 50% for all fishes you catch.
You can get the Mutation surge by spamming Sundial Totems or the Mutation Totem, and you will have a chance of rolling the Mutation Surge event on your server.
The Abyssal mutation in Fisch increases the sale value of your fish by 3.5 times. However, you can get fish with this mutation only in the Depths region, by using the Abyssal Specter Rod (25% chance) or by using a rod with the Abyssal Enchant.
