Native fish can't jump - carp jump into a trap

摘要

EUREKA, said Alan Williams one day after years of watching the Murray River as the weir keeper at Torrumbarry, near Echuca on the NSW-Victoria border. He observed that carp jump. Native fish don't. That's the carp's Achilles heel. Williams, from Goulburn Murray Water, and Ivor Stuart from the Victorian Department of Sustainability and Environment, have invented the world's first practical, low-cost method of separating invasive carp from native fish.
