A Zander is a European variant of our Walleye, and apparently some can be extremely territorial, to the point of attacking swimmers. With six attacks in a single weekend, two of the swimmers were sent to the hospital with gashes over four inches long, the local Swiss police department was forced to take action. The police first tried to catch the fish with a net, which failed, so a
hitman scuba diver was sent in to ice pick harpoon the fish. I’m not sure how he know which fish was the attacker, but while under he harpooned a 27″ Zander weighing over 17 pounds! What a whopper! The police cooked the fish and served it to local tourists for their troubles.
“It is quite unusual for zanders to bite humans”, Croci said, adding he suspected the fish was suffering from a hormonal imbalance which could be responsible for its aggression.
