That's the thing, if you read above I posted the exact description from the patch notes of how the fish net is supposed to work. It isn't just our opinion that it should automatically catch fish, IT'S IN THEIR OWN DESCRIPTION.
I've used cast nets before to catch bait fish to use to catch Snook. Never used bait to catch bait fish even though, as I mentioned above, I wouldn't even mind having to use bait (even as ridiculous as the concept is) if it would catch fish automatically. But... it doesn't.
TLDR; Fish net doesn't match the description, doesn't auto catch anything, and is nothing more than a fishing rod you can use on a moving boat. I hate it.
