The size of the fish on the server is a tiny bit bigger than the palm of a human. Those SALMON are about the size of a leg (full leg) and are heavy. Let's take a sheepshead (closet thing I could try to find. Not a fish expert). It is bigger than the fish in game and averages at about 1-3 kg. I heavily doubt that such a small fish living in a world where food is (most likely, especially fish food) scarce whill weigh a whopping 8 kilos. It weighs a bit too close to a "standard" bar of fucking gold.
