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. 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.

Event Exclusive Fisch Mutations
The mutations below can only be obtained during certain events. However, you can use the Fisch rods linked below to get them nonetheless.
Mutation Name Value Bonus Appraisable How to Get Doomsday 4x No Exclusive to the Fischmas event Firework 3.5x No Only found using the Firework Rod (15% chance) Chocolate 2.5x No Only found using the Chocolate Fish bait (100% chance) Minty 2.2x Yes Exclusive to the Fischmas event Ghastly 2x Yes Exclusive to FischFright event.

Apart from the abovementioned ones, two more mutations are currently unobtainable in the game. This includes the Sandy (1.2x sale value) and the Unsellable (0x sale value) mutations. While the former could be obtained during the Pharaohs Curse, the latter is 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 Enchantments, and King’s Rod, Poseidon’s Rod, or Season’s Rod Giant 2-2.5x Can be applied to fish during appraisal. Better found using Sea Overlord, Sea King, Abyssal 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.
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 450 cash (or 338 with 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 at getting mutated fishes. These are:
- 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
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 in the game and also provides the best value? Let us know in the comments below!
Tentacle Surge mutation (10x value) is currently the best mutation in Fisch. However, the chances to get it are 5% and only using the Kraken Rod. So, you might consider going for the Ethereal Prism Rod that gives the Prismize mutation. Although the value multiplier is 8x, the chances of getting this are 50% for all fishes you catch.
You can get the Mutation surge by spamming Sundial Totems, and you will have a chance of rolling the Mutation Surge event in 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 or by using a rod with the Abyssal Enchant.
