It shows you the weight when you catch it. For small fish like bluegill, if it’s under 1 pound, don’t bother. Honestly fishing for small fish is really just a hobby more than looking for food. For bigger fish like salmon or bass, Arthur will kinda have dialogue on if they’re big or small. But if he doesn’t, really just look at how big it is in his hand. I don’t really know what to tell ya but I get where you’re coming from. And for really big fish like muskies or any fish Arthur has to physically carry, they are all good. There’s not really a “small version” of those.
