Experts ask anglers to bin carp
THE sight of sinking trees along the river bank is enough to make Warwick and District Fish Stocking Association treasurer/secretary Ed Kemp shake his head.
“Those carp are a real problem, especially the young ones as they’re at their most active burrowing into the river bank and causing erosion. Eventually the trees will fall into the water,” Mr Kemp said.
European Carp damage waterways while feeding and sucking mud from the river banks which causes turbid water, trees to fall into the river and decimating native fish stocks like Murray Cod and Yellow Belly.
With the With European Carp’s uncanny ability to breed they prove to be a real problem for Southern Downs’ waterways.
“When you catch a carp and cut her open she’ll be full of eggs and can lay millions of eggs a year,” Mr Kemp said.
“I’ve had a carp egg – which looks like a grain of sand – on the table and I’ve tried to cut it in two with my fingers. It was impossible.
“A dry season doesn’t affect carp as their eggs can lay dormant for about five years and a formed carp fish can survive without water for about 24 hours.”
With the call of the tinnie and line season approaching Mr Kemp urged fish hunters to keep the dreaded carp catch.
“People often leave it on the side of the bank and the birds come and pick up the carcass or it gets washed back into the river system, if its female she’ll be full of eggs so by killing one carp millions more can return to replace it,” he said.
“There are bins which get emptied by council every day along the river so put them in there and please don’t release them.”
Carp have also been turned into a liquid fertiliser for the garden by Deniliquin based company Charlie Carp which processes millions of carp annually.
Estimated Australian waterways will soon reach 80 per cent European Carp.
One female 3kg European Carp lays about one million eggs up to twice a year.
