Fish bones and carcesses

[MoonCat]

What can I do with these items that I get from harvesting fish?

You can make needles for sewing out of the bones.

and fish carcasses can be used later to make ingredients for gunpowder in the pit

Fish carcasses can also be used for the composting bin after they turn into rotten food. I usually put mine into a stick container with my other rotten food and when they turn they automatically add to the rotten pile.
Pile up on needles, you will need lots later on. I am usually too cheap to use either copper or iron needles LOL.
