Net a Fish Fish Fusion and Mutations

Fusion is how Net a Fish turns clutter into power. Every duplicate fish sitting in the cooler can climb a mutation ladder that multiplies showcase value. Catching a mutated fish wild is great; fusing guaranteed steps is how you manufacture those multipliers on demand. This guide covers the cooler recipes, multipliers, when to Fuse All, how Auto Fuse fits, and how fusion pairs with events and rarity chasing.

Why fusion beats selling duplicates

Selling a stack of commons gives a one-time payout. Fusing them into Shiny, then Gold, and beyond creates fish that earn more every second in the showcase pool. Because showcase income funds Upgrades and rebirth cash gates, fusion is an income multiplier disguised as inventory management. Keep duplicates of species worth displaying; sell only true junk after your pool is full of better options. For species priority, use the fish rarity tier list.

The fusion ladder

Open the Fish Cooler and use the fusion panel. Recipes commonly tracked by players:

1. 10 normal fish → 1 Shiny (about 1.15x)
2. 8 Shiny → 1 Gold (about 1.25x)
3. 6 Gold → 1 Crystal (about 1.35x)
4. 4 Crystal → 1 Glitched (about 1.5x)
5. 3 Glitched → 1 Rainbow (about 2x)
6. 2 Rainbow → 1 Starlit (about 2.5x)

Chained end to end, a Starlit represents thousands of base fish. That is why constant casting, helpers, and pets matter: fusion is hungry. Limited event mutations such as Haunted have appeared in seasonal windows at even higher multipliers; treat those as time-limited and check Updates when events end.

You can also catch mutated fish directly. Wild mutations skip early ladder steps. Raise wild odds with Mutation Magnet fishing upgrades, luck Skill Tree nodes, mutation baits, and Shimmer Surge events described in Events.

How to fuse without mistakes

1. Collect duplicates of the same fish and mutation tier.
2. Open the cooler fusion UI and select the stack, or use Fuse All when you trust the selection.
3. Confirm. Input fish are consumed; the higher mutation appears in storage.
4. Equip Best into the showcase so the new multiplier starts paying immediately.
5. Repeat up the ladder when you again hit recipe counts.

Always glance at the selection before confirming Fuse All. Fusing the last copy of a fish you wanted to keep displayed is avoidable pain. If you are one fish short of a recipe, cast during Wave Rush or Lucky Tide instead of buying random Market fillers.

Auto Fuse and quality-of-life

The Auto Fuse game pass (often around 199 Robux) makes the cooler fuse eligible stacks automatically and continue up the ladder as counts allow. It is ideal for long sessions and AFK-friendly setups with Auto Throw and Auto Collect. Buy it after your net can hold the rarities you farm; autofusing commons into Shiny is less exciting if Legendaries still escape. Full pass context sits on game passes.

Trusted scripts that only click UI for you are discussed on Scripts. Never use tools that ask for your password.

Fusion during events and boss windows

Shimmer Surge multiplies mutation chance, so wild mutated catches spike—fuse the leftovers afterward. Gold Rush multiplies money, so fused showcase fish suddenly print faster; fuse before the event when you can. Lucky Tide and Wave Rush increase rare hauls, filling recipe stacks faster. Boss fights such as Megalodon or Kraken are not fusion recipes themselves, but the rare fish around those encounters should be fused or showcased, not sold in panic.

Pets from Pets and Crates increase how fast stacks appear. Two pets with +1 Pet Slot feed fusion better than one. Helpers from the dock do the same for common species.

Fusion and rebirth planning

Fusion products remain as fish you own; rebirth wipes cash, not your cooler collection in normal rules. Before a rebirth, fuse aggressively so your post-reset showcase still earns hard while you rebuild nets. After rebirth, the higher money rank multiplies whatever fused fish you display. See Rebirth for gates such as the first 48 fish / $30k reset and Storm Chaser Traits.

Practical fusion priorities

• Early game: fuse commons into Shiny for any species that stays in the pool.
• Mid game: push Gold and Crystal on Legendary species once Titanium Net is online.
• Late game: chase Glitched, Rainbow, and Starlit on your highest base-value fish.
• Always refresh showcase after a big fuse session.
• Pair fusion days with code redeeming from Codes so crate pets and luck boosts refill stacks.

Watch the mid-article video for rare-catch context, then return here when your cooler looks cluttered. Fusion discipline is the quiet skill that separates a stagnant dock from a dock that self-funds Mythril nets and rebirth cash walls.

Common fusion mistakes

Selling duplicates you needed for a 10-fish Shiny recipe. Leaving a normal fish displayed while a Gold version sits unused in storage. Autofusing without checking you still have a display copy. Ignoring mutation upgrades and events so you rely only on the slow ladder. Skipping Getting Started basics and trying to fuse before the showcase habit exists.

Master the ladder, keep the pool updated, and every other system in Net a Fish gets cheaper. For pet-side income that feeds more fuse fodder, keep the pets tier list handy beside this page and the tier list hub.
