x2 Fish Luck — fish rarity matters more first

Core Mechanics

Mutations appear to be random variants that can apply to any fish catch. When a mutation triggers, the fish gains a special visual tag and increased value on your island. The x2 Mutation Luck gamepass doubles the base mutation probability, making it more likely to catch mutated variants.

Advantages

Mutated fish are worth significantly more on your island than their normal counterparts. If you catch a mutated rare fish, it can be worth as much as a higher-tier normal fish — making mutations a powerful income accelerator.

Challenges

Very little is confirmed about the mutation system. Bloody and Moon mutations are based on community video captions only. Trigger rates, value increases, and the full list of possible mutations are unknown.
