Trapping might be better than fishing as far as the traps are within crawling distance.
Trapping doesn’t get penalized for encumbrance nor injuries, unlike fishing. But processing the skins is penalized for not standing*, as is the hide working for injuries.
Fishing passes time and might be good for skill increases, and the catch will be decent.
If the season permits, harvesting birch bark for crafts and alder/rowan for tanning are possible way to pass time. Takes long time and product is always decent.
Weatherlore checks and herb lore (if you have them available) are ok, but won’t pass much time.
*might even be barred from working on when fallen, I’m not able to verify this moment.
I don't like to waste, I feel like it might make the spirits angry. So I wouldn't like to trap much if I can't work the skins as well as I can. Also wouldn't like to overfish. But maybe if I retire one of my nets and start actively fishing that trains the skill faster and keeps me at my current food status of catching enough so I don't have to actually use my stores.
Bark is a good idea, thanks
I guess I should get all I can before winter
