Overview

Fish have a chance to be caught with a natural Mutation, or can be given one through Appraisal. Certain fishing rods, weather, limited-time events, admin events and events have exclusive Mutations tied to them, and they can also boost the chances for acquiring mutated fish. The Appraiser's Luck gamepass also increases the chance of obtaining Mutations through Appraisal. Each fish can have only one Mutation at a time. For mutated fish that have patterns (ex. Mosaic), the pattern is generated based on the weight of the fish.

Attributes

Attributes can further modify a Fish while being able to stack with one another and alongside a Mutation; for example, a Sparkling Shiny Big Silver Isonade is one possible combination. This makes Attributes desirable when appraising, as the sell value of the fish can be raised substantially.

Attributes such as Shiny and Sparkling have no risk of being lost during Appraisal. Other attributes, such as Big and Giant, do not affect the sell value of a fish, but rather indicates that the fish's weight exceeds its base weight by a certain threshold. Big and Giant can be lost through appraisal when the fish's weight has depressed enough.

There are currently 4 attributes available in the game:
