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

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.

Good source of prime fish meat when using a sickle

Use a Barry kill one once they swarm use the water spin attack, I have fish 4 days

Tame an army of them using the fish baskey and rule the oceans and rivers
