3. 3) EAT THEM.
4. 4) TRAP THEM.

Why are carp a problem in Australia?

Carp contribute to environmental degradation in the Basin. Reported impacts from carp include reduction in water quality, river bank damage and may contribute to algae blooms. The increased spread of carp and its impact on freshwater habitat has come at the expense of native fish species and aquatic vegetation.

What problems do carp cause?

Why are carp a problem? Asian carp cause serious damage to the native fish populations in the lakes and rivers that they infest because they out-compete other fish (video, 1 min) for food and space. Carp are also thought to lower water quality, which can kill off sensitive organisms like native freshwater mussels.

Are carp good for a pond?

What eats a common carp?

Predators of young carp include larger fish like northern pike, walleye and largemouth bass. Birds such as great blue herons also feed on young carp. Humans are the primary predators of adult carp.

How do you get rid of invasive carp?

Eradicating an established population of Asian carp would be extremely difficult and expensive, if possible at all. Potential control methods include the use of fish poisons, physical barriers, physical removal, habitat alteration, or the addition of predators, parasites, or pathogens.

What do you do with an invasive carp?

If you think you found an invasive carp, freeze the fish in a sealed plastic bag, note the date and location, and call your local department of natural resources or environmental quality.

What can carp be used for?
