A shoreline location that remains accessible for checking catches.
Craft the Survival Fish Trap; its recipe uses Wood and Cloth and does not require a workbench.
Carry bait before leaving base, since the trap cannot work unloaded.
Find a shoreline spot where the deployed trap can be reached again without exposing your return path.
Place the trap on shore and load it with bait.
Leave it to operate, then return and inspect for a catch; the trap increases Trout odds as more bait is loaded, but it does not guarantee a result.
Collect any fish and keep the trap rather than abandoning it if the area remains useful.
Reload bait when you want to continue the passive fishing cycle.
Farming tips
The trap is a passive alternative to actively steering a rod through the fishing minigame.
Use only as much bait as you are willing to leave at the shore; no fixed catch count is guaranteed.
Repeat, collect and use
Repeat by checking the trap, collecting any catch, and reloading bait. Treat each visit as a chance to replenish food, not a guaranteed timer or yield.
Common mistakes
Placing the trap inland: it is designed to sit on shore, so deploy at the water edge.
Expecting Trout without bait: load bait before leaving it.
Assuming a loaded trap guarantees fish: increase bait to improve the chance, then plan around uncertain catches.
When to stop or switch
Stop checking when your food stock is adequate or the shoreline is no longer safe to revisit.
