In the mobile, you can’t use fish but you can use the normal passive taming method to tame them.
Otter

Player-written tips for taming, using, and fighting the Otter in ARK: Survival Ascended & Evolved.
These guys are cute but you dont want to get to close to an otter. They are very capable of ripping your face off, and they will do it.
For anybody playing on mobile, it’s just a passive tame with raw fish meat and raw prime fish meat.
I saw one of these fellas in a nearby river surrounded by spinos, fortunately I was able to reach it, but the thing is I am a total noob so I tried to knock it out and feed it some fish but right after I did so my dodo murdered it without any hesitation, the poor thing squeaked…

Its found in all the rivers so scan those and don’t head towards dangerous areas because they wont me there
These little guys can hold multiple copies of the same artifacts in their inventory. Best artifact hunting tame in game. Common spawn in Aberration’s river where the river runs toward a waterfall that leads to the blue zone.
Upgrade there carrie weight and it can carrie artifacts
To tame an Otter, simply interact with it (default "E" on PC) while dragging any kind of fish. Sabertooh Salmon is the best, Coel is the worst. Fish size matters more than type, so Megapiranhas are often worse than large Coels. When dragging large fish, chances are…
To tame an Otter, simply interact with it (default "E" on PC) while dragging any kind of fish. Sabertooh Salmon is the best, Coel is the worst. Fish size matters more than type, so Megapiranhas are often worse than large Coels. When dragging large fish, chances are high that it will obstruct the vision while standing still; Just walk/swimm to the Otter and feed it before coming to a stop in order to keep the fish carcass behind you.
Quite common on Aberration, Otters spawn at large numbers from where the Fertile River delta splits in two (not going to the Fertile Lake) until its fall to the Luminous Marshlands. It's also worth note that the northern section has neither large predators nor Megapiranhas and Mantas on most of its lenght.
No other map has such a noteworthy spawn, but they can be found on most Redwood Forest lakes except for The Center, where it is unadvised to look for them.
Found easily in rivers on Abberation, near Spino spawns and are easy to spot by the cluster of fish protecting them. Sometimes you will see a Carbonemys swimming on top of a group. They eat a lot.
Don't plan on making a fuzzy otter army or Otterman Empire, unless you have a lot of fish income. Upping oxygen and melee may boost insulation, but with the level 55 (88 after tame) I got last night, it was only 12 hours before his food stat was dropping... already had one…

Farm artifacts just boost weight and its can carry till its overcumbered say its weight 100 and the artifact weight 5 lbs 20 right there
When breeding otters throw Mum into a wooden cage, stand in there when she's ready to give birth and then it tends to make it easier to imprint on the baby. Saves you building a room for them unless of course you already have one spare
Multiple otters common spawn at 30 58 ish in the river right before it dumps into the blue zone. Just punch one and every otter in the area will come attack you. Lead them up onto land to allow an easy tame once they stop being hostile (which occurs quickly).
On mobile you can just feed it raw fishmeat instegs of whole fishes
Otters can attack and harvest while riding on your shoulder. The damage it deals isn’t much compared to other natives of the Island, but it’ll definitely help to kill the enemy before they kill you. Just watch out for the pikes or spears.
Where can I find an otter. Please tell me
Great 4 getting artifacts goes off weight.
If you can't find a otter in the normal spot you always do try killing some coel.
I found an otter and then a compy attacked me and then my raptor went to kill it but the otter was beside it so I died I was so sad. R.I.P otter
I just tamed and otter and put a hat on him.
If you have soothing balm give that to the otter after you feed it it’s first time then use soothing balm and feed it again that’s how mine tamed at the second feed.
