Once killed use a sickle to get the must Prime Fish Meat.

Using a sickle is a fast and easy way to get raw prime fish meat! Helpful for taming water dinos.

I see the big ones frequently, and I recommend you catch it with a fishing rod. The bigger it is the better the rewards. I got a weapon blueprint once, the piranhas can be decent too sometimes but, salmon are way better. Well, usually they are, it's best to fish for them that to kill them regularly. Hope this helps.

Under appreciated. Super easy to find, and drops PRIME FISH. Prime fish is almost as good as regular prime meat, and WAY better than regular meat. Use a sickle to get tons of prime fish. Super useful for taming carnivores if you don’t have the kibble

I saw one that made me not believe my eyes.

One that glimmered and shined with colors unique.

I saw one with red scales so bright,

That became every color of the rainbow under the light.

I chased and pursued it, but never caught up.

Until one day I found it again.

And let’s just say,

It lives in the lake inside my base today.

Shown as terrestrial, although it is FISH

You can tame with basket from aberration then keep in a holding pen for easy on demand prime fish meat
