1: Do not fight them in water under any circumstances
2: Lure them on to land
3: Use a bola
4: Attempt to Tranquilse with bow and arrow or better
Remember: They can only be tamed with fish meat and they usually kill all the fish in the area so you should probably have some prepared beforehand.

Get on top of a rock and unload shock darts with you buddy!

Can be feed raw meat just has to be fed manually not automatically.

If you are a low level don’t go after them unless you have a bola or two high level carbos
