What Are Fish Mutations in Abyss?

Fish mutations in Abyss are special variants of regular fish that feature unique appearances and significantly increased sell values. When you’re fishing in Abyss Roblox, there’s a chance that any fish you catch will spawn with a mutation, making it more valuable and visually distinctive. These mutations aren’t just cosmetic changes – they provide substantial multipliers that can dramatically increase your income when selling fish.

Each mutation has its own spawn rate and multiplier value, with some being incredibly common while others are extremely rare. The rarer the mutation, the higher the multiplier and the more impressive the visual effects. This creates an exciting hunting dynamic where players actively seek out the most valuable mutations to maximize their profits.

How Fish Mutations Work

Understanding the mutation system is crucial for success in Abyss. Here’s how it works:

Random Spawn System

Mutated fish spawn randomly when fishing, with each mutation having its own hidden rarity percentage. The game uses a complex RNG (Random Number Generator) system that determines whether a fish will spawn with a mutation and which specific mutation it will be.

Location-Based Mutations

Some mutations are location-specific, meaning you can only find them in certain areas of the game world. For example, the Abyssal mutation can only be found in The Depths, making it a special prize for players who venture into these dangerous waters.

Event-Based Mutations

Certain mutations only appear during specific events or conditions. The Rainbow mutation, for instance, has a 30% chance to appear when catching fish during a Blue Moon event, making it a limited-time opportunity for dedicated players.

Visual Identification

Each mutation has a distinct visual appearance that makes it easily identifiable:

Abyssal: Bright blue to purple coloring with ethereal glow
Angelic: White and golden hues with divine aura
Rainbow: Multicolored shimmer effect
Nuclear: Green radioactive glow
Gold: Shiny golden appearance
Albino: Pure white or pale coloring
