Many studies show that bighead and silver carp substantially change ecosystems where they have been introduced. Studies around the world, including a USGS study in the Missouri River, found that zooplankton populations are dramatically reduced when Asian...
An exponential increase in the population numbers of bighead and silver carp began in the mid-90s and continued through the mid-2000s in parts of the Mississippi and Illinois rivers. The Illinois Natural History Survey has estimated that a population of...
Both bighead and silver carp become fairly large; records of both species approach 100 pounds, but silver carp over 20 pounds and bighead carp over 30 pounds are uncommon. The North American record for bighead carp is a 106-pound fish from Missouri. Both...
It has spread from South Carolina all the way down to Florida, west into Texas, and has now been located in California. For more information about this invasive species, read Chinese Tallow: Invading the Southeastern Coastal Plain.
Chinese tallow has been cultivated in nurseries and sold as an ornamental tree used for landscaping; however, it is now classified as a nuisance species in some locations and can no longer be sold. It has separate pollen and seed-bearing flowers, and...
The capture and movement of wild-caught baitfish is of special concern for spreading Asian carp. Young Asian carp could easily be transferred, as baitfish, from one body of water to another. In particular, juvenile silver carp sometimes school with...
Eradication of any established population of Asian carp would be extremely difficult and expensive, if possible at all. Effective management of established invasive species that cannot be eradicated usually employs integrated pest management. This...
Silver carp have been observed to leap into the air simultaneously as an apparent fright reaction to rocks thrown in the water, passing trains, geese taking off from the water, or when they unexpectedly find themselves in a tight place. Speeding boats...
Tallow has been cultivated as a seed-oil crop in China for at least 14 centuries. Candles, soap, cloth dressing, and fuel are made from the tallow. Chinese vegetable tallow is a solid fat that is in the outer covering of the seeds. The kernels produce an...
Asian carp are found in the great rivers of the central United States, especially in the Missouri, Illinois, and Mississippi Rivers. Bighead and silver carp are not known to be established outside the greater Mississippi and Mobile River basins, though...
