Carp targeted in scientific eradication

Scientists from the Arthur Rylah Institute can be seen removing a large carp from the Murray River.

Scientists from the Arthur Rylah Institute descended upon Lake Mulwala on Monday to participate in a targeted carp eradication program along the base of the Yarrawonga Weir.

This program was coordinated by Kelvin Berry from the Wangaratta Sustainability Network (WSN) who said conditions were perfect to have an intensive carp cull on this section of the Murray River.

“The introduced species like the warmer water at the edge of the weir wall and will rise to the top to eat the algae which forms on concrete structures,” he said.

“The WSN formed a partnership with the Arthur Rylah Institute, a division of the Department of Environment, Land, Water and Planning in 2014 and since then we have secured Communities for Nature Funding to assist with our carp removal program.

“WSN volunteers travel with scientists from the Institute and these volunteers take the carp for the scientists and dispose of them humanely in an environmentally friendly way.”

Monday’s intensive collection of carp used electronic stunning equipment specifically along the Yarrawonga Weir Wall.

“Three boats targeted the carp this time,” Kelvin said.

“Goulburn Murray Water has regulated the flow through the gates in the lead up to attract the European carp to the area.

“We normally take care of around 150km of the Ovens River waterway but this was too good an opportunity to miss.

“Between 2014 and 2016 we have taken six tonne of carp out of the Ovens River which has reduce the biomass from 85% to just 35%.”
