So in real life, I am an outdoorsman for over 40 years… I hunt, and I fish.
I have made and used traps to catch fish just like the ones you show in your game.
In real life, fish traps do not need bait. In many cases the fish just swim inside looking for a place to hide.
Don’t get me wrong, bait helps and fish get caught sooner, but eventually small fish will sneak into a basket trap just looking for cover from predatory fish.
If anything, let the small blue piranha swim into an empty trap over a long period of time. That would at least mimic real life nature…
Just an expert opinion, Thank you
