Is there any use for live fish, and how can you keep them alive?
In Don't Starve, when you pull a fish from a pond, it flops for a few seconds, then dies.
Is there any purpose to the live fish? Or is it merely window dressing animation?
If there is a use, what do you use to keep them alive?
As the wiki states under Trivia it's just a fancy animation. The fish cannot be kept alive and there is no practical use to the live fish.
When Fish is on the ground, it flops around, then perishes, its eyes becoming crossed out.
