An Ark dev said that these will be tameable in the future!

I tamed this with force tame but you can also tame it with fish basket

Tamable using fish baskets from aberration. They seem to flee from the baskets once placed. It is a good strategy to pen then in with fence foundations and walls, or kite them to a pen. Place your basket on the other side of the wall and catch.

I killed these guys with ez just taame a icthy and craft saddle(or just do quest tame ichty when its tamed free saddle) And kill em ez imma tell one more time tame icthy put on saddle ride icthy and KILL THESE BAD BOYS BABY

They’re scared of baskets so if you want one make a pen

You can tame them with a fish basket, catch them with fish basket and release in water and it's tamed

Place a fish basket to tame this.

Trap them in the shallow water so they cannot go anywhere and just place the bucket on the top of them. Bam. Tamed Sabertooth Salmon

Fish Basket only on Aberration.
