Ducks are cute, eels aren’t – and it’s costing them their lives, says Auckland Council. Residents are being asked not to harm or remove eels (tuna) from ponds after reports of netting them to protect ducklings. “As a freshwater predator, tuna play a key role in regulating other animal populations,” Freshwater Regional Advisor Matthew Bloxham says. “It’s critical for species like mallard ducks, which have few natural predators.” He says ducks can be a nuisance, exploiting resources and breeding quickly. Their numbers have given rise to other control methods, such as shooting.
