  In the Tan Dynasty (7 th –10 th Century) there was a transition period from common carp culture to the rearing of grass carp, black carp, silver carp and bighead carp. From the 10 th to the 12 th Century, expansion in the production of these four cyprinids was even greater, and the feeding habits and relationship between the species became. unresolved issues are presented in Appendix ‘Use of triploid black carp on aquaculture facilities’, Appendix ‘Use of grass carp on aquaculture facilities and farm ponds in watersheds with self-sustaining populations of grass carp’, and Appendix ‘Commercial, domestic transport of live farm-raised bighead and grass carps.’. Four species of Asian carp—silver carp, bighead carp, grass carp and black carp—were imported to the United States in the s. The species, called “Asian carps,” have striking characteristics, in particular the considerable size that they can reach, their growth rate and reproduction rate. Facts About Invasive Bighead and Silver Carps Background and Problem • Bighead and silver carp, together the “bigheaded carps”, are native to China. In North America, the term “Asian carps” is used to refer to the bigheaded carps together with the also-invasive grass carp and black carp, or sometimes to the bigheaded carps alone.

  Silver Carp. Silver carp are very similar to bighead carp in many ways and are native to the same areas as the bighead carp. There are some differences between the two though, one that stands out the most is their tendency to leap out of the water and go airborne when disturbed. Esteemed game fishes in their home waters, they are often considered a nuisance in North America. Carp are big, canny, hard-fighting fish. The mainstream angling community scorns these hard-fighting invaders, but that doesn't prevent smart and resourceful fishermen from enjoying this . An identification key to introduced Asian carps and other cyprinids, including black carp, is provided by Schofield et al. (). The black carp closely resembles the grass carp Ctenopharyngodon idella. The two species are similar in overall body shape, size and placement of fins. Both black carp and grass carp have very large scales.   The name "Asian carp" is actually an umbrella title for four different species: bighead carp, black carp, grass carp and silver carp. Some of the larger species can weigh up to pounds and have an uncanny ability to jump out of the water. Females can produce upwards of 2 million eggs, and some of the fish can live for 20 years.

Both species have similar thermal requirements, with a minimum developmental temperature for embryonic stages of ° C for silver carp and ° C for bighead carp, and ° C for silver. Bighead, silver, and grass carps are invasive in the waterways of central North America, and grass carp reproduction in tributaries of the Great Lakes has now been documented. Bighead and silver carp eat the same plankton that native baitfish and larval gamefish eat; however, the grass carp eats plants that provide habitat for fish and food for waterfowl. Grass carp were brought into U.S. waters to control aquatic plant growth and stocked (legally and illegally) in ponds, canals, impoundments and lakes. Asian Carp. Four species of Asian carps, bighead carp, silver carp, black carp, and grass carp, are threats to Great Lakes peer-reviewed risk assessments for bighead carp and silver carp, and grass carp indicate that the Great Lakes are at substantial risk from these three species. The primary threat from Asian carps is competition with other fish for food resources, and the.
