What is the Sunken Mutation?
The Sunken mutation is a rare and highly desirable effect in Fisch that transforms ordinary fish into valuable treasures. When a fish receives this mutation, it emits a distinctive strong green aura, making it easily recognizable. Most importantly, it multiplies the fish’s sell value by an impressive 6.3x, making it one of the most profitable mutations in the game.
Originally introduced in version 1.05.0, the Sunken mutation has undergone several balance changes over time. It started with an 8x multiplier, was reduced to 4x in version 1.07.1, then progressively buffed to 4.5x in version 1.58.0, and finally reached its current 6.3x multiplier in version 1.63.4. This evolution shows the developers’ commitment to making the Sunken mutation a worthwhile pursuit for dedicated players.
How to Get the Sunken Rod: Complete Step-by-Step Guide
Step 1: Obtain Treasure Maps
The journey to getting the Sunken Rod begins with Treasure Maps. Here’s what you need to know:
Treasure Map Drop Rates:
- Base chance: 1/160 (improved from 1/350 in recent updates)
- Maps are caught randomly alongside regular fish

- Maps are consumable items stored separately in your inventory
Best Fishing Setup for Map Farming:
- Use Fast Rod or Rapid Rod for maximum catch rate
- Focus on high-frequency fishing locations
- Consider using Fisch codes for lure speed boosts
- Fish during optimal conditions (weather, time of day)
Step 2: Fix Your Treasure Map Coordinates
Once you obtain a Treasure Map, you’ll notice the Y and Z coordinates are missing. Here’s how to fix them:
