A mutation system was added to Spear Fishing with the Iceborne Update. Along with the base versions, you can now catch mutated versions that have changed appearance and increased value. This guide will tell you everything you need to know about the Spear Fishing Mutations system, including how to catch mutated fish, spawn locations, and more.
All Mutations in Spear Fishing
There are six mutations in Spear Fishing. Fish randomly spawn with these mutations during certain Climates and Weathers. See the table below for a complete list of all mutations, their multipliers, and the climates/weather conditions that spawn them.

Spear Fishing Mutations FAQs
Mutated fish can spawn in all locations in Spear Fishing, and you can catch them just as you would catch any other normal fish, using a Harpoon or a Speargun. Baskets can also catch mutated fish if they spawn near them.
Fish that spawn with the big mutation are a lot bigger in size than the base versions. If you want a big fish, look for fish that have a maximize icon (purple color with four arrows) floating over them.
Yes, you should catch as many mutated fish as you can in Spear Fishing because they not only sell for a higher price, but you also get Gems by discovering new fish mutations in the game.
No, there is no connection between bait and mutated fish. Using a bait will not increase the spawn rate or spawn chance of mutated fish.
Right now, there are three climates in Spear Fishing: Grassland, Marsh, and Iceborne. The climate changes every 10 minutes. Each climate has different fish that players can only catch when that climate is active. Moreover, Marsh and Iceborne Climate can also mutate fish.
There are three types of weather in Spear Fishing: Rainy, Snowy, and Sunny. The weather changes every 4 minutes. Rain and Snow mutated fish can spawn during the respective weather. Sunny weather doesn’t have any mutations yet.
