Use for Fish

[henke37]

Of all the resources in Factorio, Fish is the least popular one. It is used in exactly zero recipes and can't be automatically mined. Many players don't even know that you can mine the fishes!

For those who don't know what they can be used for, they can be eaten. To regain some health. That's it.

So what can be done to make the Fish more useful/interesting?

Introducing some sort of hunger system is of dubious use and best left to mods. I just don't think it would be fun.

A setup to automatically eat them? Hard to give a convincing story for that one and largely redundant from shields anyway.

So what else is there to do with them?

Main issue from modding perspective is that there's no easy way to determine when fish is eaten.

As for catching them (wait about 60 seconds for the fish to appear in this GIF...):

I once used fish as signal in my circuit network. Perfect since I never have it stored.
One of my unfinished projects is to use fish as a "ticket" to call a train to a specific station.

That avatar is great, I've seen it before. Then I tried it in-game. Disappointed that it doesn't actually work

That sounds like a pretty good use for it actually!
