Several stains of carp, originating from both Europe and Asia can now be recognised from wild populations. Carp are now widely established throughout the Murray-Darling Basin and can also be found in all states and territories except the Northern Territory. Carp are very common in parts of this range in Australia and are considered to be one of our major pest fish species. Carp are known as a generalist species because they tolerate a wide range of conditions and habitats. However, they usually prefer slow-moving rivers or lakes with soft vegetated sediments. Their tolerance of a wide range of habitats means that they are less affected by habitat disturbance than many native species. They normally live in a preferred temperature range of around 15–32oC, but are able to survive in a wide range of temperatures, including ice-covered lakes (at about 2oC) and much warmer ponds (up to about 40oC). Carp are able to tolerate poor quality water with low oxygen levels, and water that is slightly salty. In Australia, carp are generally rare at high altitude and uncommon in clear, fast-flowing streams. Juvenile carp are usually found strongly associated with aquatic plants in marsh areas or river backwaters for the first year of their life. Carp feed by sucking soft sediment from the substrate into their mouths, where food items are separated and retained and the sediments are ejected. This habit often leads to a suspension of sediment in the water where carp are feeding. This feeding method also means that carp prefer areas with soft sediment, such as slow river pools and backwaters or lakes and ponds. This feeding habit is likely the cause of their main environmental impacts. Many of the claims regarding carp’s environmental effects are difficult to confirm because of the lack of information on waterway health before their introduction. For many waterways the decline in habitat quality took place before the presence of carp — due to activities such as catchment clearing, removal of bankside vegetation, de-snagging, stream channelisation, pesticide use and overfishing of native species. However, when a species makes up more than 80% of the biomass at some sites, as has been recorded for carp in Australia, it is difficult to believe that their environmental impact will not be significant.

  • Pest Risk Assessment for Asian Carps in Oregon
    Pest Risk Assessment for Asian Carps in Oregon IDENTITY Name: Asian Carps The common usage of the term “Asian Carps” encompasses the following four species of introduced carp (there are additional species of carp native to Asia that have been introduced into the U.S. but are not commonly included under term “Asian Carps” – see text). • bighead carp (Hypophthalmichthys nobilis) • silver carp (Hypophthalmichthys molitrix) • black carp (Mylopharyngodon piceus) • grass carp (Ctenopharyngodon idella) Taxonomic Position: order Cypriniformes, family Cyprinidae [carps and minnows] The family Cyprinidae is very diverse – it includes species that feed on plankton, herbivores, omnivores, piscivores (fish eaters such as our native pike minnow) and species like the black carp whose teeth are specially modified to crush the shells of mussels and snails - and as such it can be difficult to distinguish native versus nonnative species based on a few simple characteristics. Nevertheless, the collection of nonnative species such as Asian carps should be reported to the Oregon Department of Fish and Wildlife. Positive identification is crucial and for this reason we recommend retaining the specimen if possible or documenting the catch with photographs. Well-focused images that show the whole fish from various angles as well as close-ups of the head and fins are ideal. Additional information on identification of Asian and other nonnative carps has been compiled by the US Geological Survey and can be accessed online <http://fisc.er.usgs.gov/Carp_ID/index.html>. RISK RATING SUMMARY Relative Risk Rating: HIGH Numerical Score: 6 (on a 1-9 scale) Uncertainty: Moderate This Risk Evaluation summarizes much of the information previously compiled by the USFWS in 2008.

  • Asian Carp Factsheet
    ASIANINVASIVE SPECIES PROFILE CARP David Riecks, UIUC/Illinois-Indiana Sea Grant sian carp are a group of fish in the minnow family that are native to Asia. The term “Asian carp” refers to Bighead carp, Silver carp, Grass carp, and Black carp. Each of these species was intentionally introduced into the United States for different purposes; however, all are now considered invasive. Invasive species are plants, animals, and Aother organisms that are not native and have the potential to cause harm. Asian carp compete with native species and pose a threat to Indiana’s aquatic ecosystems. Why Asian carp are a problem Where Asian carp • Reduce game fish populations: Because Asian carp are found in Indiana reproduce rapidly, their explosive populations reduce the Asian carp were originally imported number and health of other fish. to the southern United States to • Threaten human health: Asian carp (specifically Silver Carp) help aquaculture and wastewater often jump out of the water when disturbed by boat motors, treatment facilities keep retention causing damage to boats and potentially harming passengers. ponds clean.

Alought the percentage may seem small as an average (Approx. 17% per annum) large flows have at times contributed markedly in times when the Lower Murray River had periods of low or no flow. This was especially evident during the Millennium Drought when a large flow was shepherded through to the Lower Lakes and Coorong thereby averting what would have been a natural disaster and the possibility of Adelaide running out of water.
