The Mutant Runic Koi is the newest secret fish in Fish It’s Aquatic Machine update.Unlike most secret fish that lean…
The Lucky Gold mutation in Fisch is a limited-time fish mutation introduced during the St. Patrick’s Day event (March 14–21, 2026). Fish with this mutation appear golden with light green markings and sell for 6.14× their base value making it one of the best money-making mutations in the game. You also need Lucky Gold fish to complete specific event quests on the Shamrock Express.
Here’s a quick overview of all five methods:
| Method | Chance | Notes |
|---|---|---|
| Clover Cluster Bait | 50% | Best method — use every cast |
| Clover Storm Admin Event | 20% | Second-best; server-wide |
| Rainbow Pool Fishing | Unknown | Spawns every 45 min |
| Natural Event Fishing | 0.071% | Anywhere during event |
| Lucky Appraiser (NPC) | 0.054% | At Shamrock Express only |
This is the most reliable way. Clover Cluster bait gives a 50% chance of catching a Lucky Gold mutation fish — meaning every other cast can yield one. To get Clover Cluster bait:
Always fish with Clover Cluster bait whenever you’re farming Lucky Gold mutations. No other method comes close to this drop rate.
When a Clover Storm admin event triggers, all fish caught during the storm have a 20% Lucky Gold mutation chance. This is a server-wide event you can’t control, but it’s the second-best method when it’s active. Keep an eye on the server event notifications and switch to active fishing immediately when one starts.
The Lucky Rainbow event spawns every 45 minutes, announced via a server-wide notification. When it appears:
Fish caught in this pool have a chance to carry the Lucky Gold mutation. Note: other players can grab the Gold Coins first, so move fast. Using a private server helps avoid competition.
Located on the Shamrock Express, the Lucky Appraiser can randomly apply the Lucky Gold mutation to any fish you appraise. The chance is 0.054% per appraisal — very low, but it’s a passive bonus while you’re completing quests aboard the ship. The regular appraiser does not apply this mutation; you must use the Lucky Appraiser specifically.
During the Shamrock Seas event, every fish you catch has a 0.071% base chance of spawning with Lucky Gold mutation — no special bait or location required. This is negligible as a primary strategy, but it means every cast anywhere on the map has a tiny bonus chance. Equip your best luck-boosting rod to marginally improve odds.
It’s a limited-time mutation from the St. Patrick’s Day event that turns fish golden with light green markings and multiplies their sell value by 6.14×.
Using Clover Cluster bait is the best method, giving a 50% chance per catch. Get it from the Clover Captain NPC or by redeeming active Fisch codes.
No. Only the Lucky Appraiser NPC on the Shamrock Express can apply this mutation during appraisal.
Absolutely. Beyond the 6.14× sell value multiplier, certain Shamrock Express quests require Lucky Gold fish to unlock exclusive cosmetics and the ultimate quest reward.
Yes, fish you’ve already caught with Lucky Gold mutation stay in your inventory with the mutation intact. However, you can’t obtain new Lucky Gold fish once the event ends on March 21, 2026.
