While Stardew Valley offers players a wide variety of fish, Legendaries are the most valuable trophies, and 
Mutant Carp is one of them. Since Mutant Carp is one of five members of the first generation of legendary fish, players can catch just one of these carp for one save or one for each player when playing cooperatively. High rarity makes it a desirable catch for any fisherman, and fortunately, it is relatively easy to catch.
Having reached fishing level six, players will need about 10–15 attempts to get this creature, but finding it is not easy. Rumors say that children heard strange noises on the beach east of the Hat Shop. It might be worth finding out more about this.
Updated on April 28, 2025, by Artur Novichenko: In this guide, you will learn how to catch Mutant Carp in Stardew Valley. We have added ways to get more than one Mutant Carp. Also, you can now use Legendary fish and Jewels Of The Sea book to get Roe.
Stardew Valley: How To Get Shrimps
In this guide, we will tell you about all three methods you can get Shrimps in Stardew Valley, as well as how to use them.
Where To Catch Mutant Carp in Stardew Valley
To find and catch Mutant Carp in Stardew Valley, players need to head to The Sewers and fish in the local wastewaters. The chance of catching this legendary fish is 10%, or 20% if you use Curiosity Lure. In addition, you can catch it in all seasons, at any time of day, and regardless of the weather conditions. The only significant requirement to catch this fish is Fishing Level 6, so start leveling up this skill as early as possible. It will probably take you no more than ten attempts to get this fish, but this will only be true after you gain access to The Sewers.
After heading south of Leah's Cottage and crossing a few bridges, you'll reach a small beach and see a couple of kids near a sewer grate. They will run away after hearing strange sounds coming from inside, but you can't log in to check what's there. The only key to The Sewers is kept by Gunther, curator of the Museum and Library. However, he will gladly give it to you when you bring him 60 artifacts.
In the Stardew Valley world, artifacts are prehistoric objects, minerals, relics, and some other items you can find in the wild or obtain from Geodes. So you shouldn't expect to collect them too quickly. But as soon as you fulfill this condition and receive the key, everything is simple. Go to The Sewers and start fishing until you catch a Mutant Carp. Please note that this is a very nimble and agile fish, so having a good fishing rod and Trap Bobber will be an advantage for successful fishing.
How to Get More Than One Mutant Carp
Classic fishing in Stardew Valley will only net you one Mutant Carp. Luckily, players can use a special bait to get around this rule. You'll want to use Challenge Bait to catch up to three of the same fish at a time. It's worth noting that you should use this trick right away, as once you catch a Mutant Carp with your fishing rod, you won't be able to get it again.
Stardew Valley: Best Boots
Stardew Valley's wide variety of boots can give the player helpful buffs, but which pair is the best?
How To Use Mutant Carp in Stardew Valley
Even though you can catch up to three Mutant Carp per save in Stardew Valley, it's still more of a valuable trophy than a resource for everyday use. Instead, you can farm Radioactive Carp, an alternate version of this fish from the second generation of Legendary Trophies. However, if you're still looking for ways to put Mutant Carp to good use, here are a few options:
- You can sell it for 1,000 - 3,000g, depending on rarity.
- Use it to cook Maki Rolls, Sashimi, or Quality Fertilizer.
- Use it as a green dye.
- Place it in the Fish Pond.
The last method is the best one, as Mutant Carp will produce one to for Roe for you. Alternatively, players can get Roe from fishing treasure chests, provided they have read the Jewels Of The Sea book.
