Fisch mutations come from different routes: some are tied to rods, bait, enchantments, fishing conditions, or events, while others can be changed through an NPC. The community-run Fisch Wiki reported 173 obtainable mutations in update 1.89.0 on September 29, 2026, but its mutation page carries an outdated-information warning. The entries below are the routes documented in the available source material—not a complete or independently verified live-game roster.
How mutations work
A mutation changes a fish’s appearance and can affect its sale price; the listed price multiplier depends on the mutation. The Fisch Wiki says a fish can have one mutation at a time. It describes Shiny and Sparkling, as well as size attributes, separately from that mutation slot.
Because the wiki flags its page as outdated, treat its reported count, chances, and route details as a dated community reference rather than official or guaranteed current game data.
Documented mutation routes
These examples show why there is no single method for obtaining mutations. A chance listed by the wiki is specific to the stated route or condition; it should not be read as a universal chance for that mutation.

| Mutation | Route listed by the Fisch Wiki | Reported chance or condition | Appraisal route | Version or event note |
|---|---|---|---|---|
| Aether | Natural fishing | 0.004%, as reported by the community wiki | Not stated | Wiki page updated September 29, 2026; marked outdated |
| Fury | Use the Carrot Rod, or fish in a Carrot Pool spawned by that rod | 15% for the rod; 15% for the spawned pool, which the page says applies to all players | Not stated | Wiki page updated September 29, 2026; marked outdated |
| Purified | Take an Amber-mutated fish to the Chiseler at Ancient Isle; the page also lists the Insight enchantment | The Chiseler result may be Purified or Revitalized; the page lists a 30% chance for Purified with Insight | Yes: Chiseler at Ancient Isle, C$100 | Wiki page updated September 29, 2026; marked outdated |
| Revitalized | Take an Amber-mutated fish to the Chiseler at Ancient Isle | The page says the result can be Purified or Revitalized | Yes: Chiseler at Ancient Isle, C$100 | Wiki page updated September 29, 2026; marked outdated |
| Blue Moon | Fish with any rod during a Blue Moon | 20% while fishing during the condition, as reported by the community wiki | Not stated | Condition-based route; wiki page marked outdated |
All chances and route details in this table are claims from the Fisch Wiki’s mutation entries, not independently confirmed official statistics. The page’s reported count of 173 obtainable mutations refers to update 1.89.0 and was published alongside an outdated-information warning.
Which route should you try?
- For a rod-specific mutation: Check the exact rod and any passive or spawned-area condition attached to the entry. Fury, for example, is listed through the Carrot Rod and its Carrot Pool.
- For an enchantment route: Check whether the chance applies to a particular mutation rather than all fish. The wiki lists Insight as a 30% Purified chance.
- For a timed condition: Blue Moon is listed as a fishing condition that works with any rod, rather than as a dedicated-rod route.
- For an NPC route: The Chiseler entry requires an Amber-mutated fish and C$100, and gives either Purified or Revitalized according to the wiki.
- For an event-associated mutation: Check whether the entry lists a separate rod or bait route. The wiki lists Gravy with the Cornucopia Rod and several bait options despite its association with Fischgiving 2025, and Ghastly and Sinister with the Haunted Rod despite their association with FischFright 2024. Those listed alternatives mean the event association alone does not establish that a mutation is permanently event-locked; current availability still needs in-game confirmation.
What this route list does—and does not—cover
The five mutation entries above are a sourced subset, not an exhaustive list of every mutation. The available route details do not establish a complete mutation-by-mutation roster, multipliers, appraisal availability, or current odds for all 173 mutations reported by the wiki. Do not infer an unlisted mutation’s method or chance from these examples. For a target not shown here, consult the current in-game information and check the wiki entry against the live game before spending bait, changing enchantments, or pursuing a time-limited condition.
