If you go to a certain spot on ragnorok (i forgot what its called) but its next to the canyon the spinos spawn in. You can see these them jump out of the water and try to swim up the waterfall i just think thats a cool detail its the onl time they can get out of the water without instantly dying
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.
You don't need to build a pen to tame, I just tamed my first thanks to the tips on here. Just wait and check the traps that have salmon near and when the basket says pick with salmon (words to that effect) pick it up and you've tamed a salmon! Thank you 😘
