One thing is certain in this game is that you need fiber for many reasons. So grab your sickle, gather some thousands of it and hain insects too. Toss the insects in the deep fishing traps and go for an adventure. When you’ll return you’ll have your fishes waiting for you. Whatever you don’t need make them oil, the rest in the preservation box. If you have a couple compost boxes too it’s more than ok.
Fishing trap is passive fishing.
