A strong buccal pump forces water through this filter. Habitat Preference. By weight, more silver carp are produced worldwide in aquaculture than any other species of fish except for the grass carp. [14] Boaters traveling in uncovered high-speed watercraft have been reported to be injured by running into the fish while at speed. Because of their preferred food items, they may provide direct competition with native fish larvae and juveniles. Silver carp (Hypophthalmichthys molitrix) was imported from China in the 1970s for use in aquaculture ponds to control plankton. The genus name Aristichthys has also sometimes been used for bighead carp, but is deprecated.

Silver carp feed primarily on phytoplankton and can out-compete many native fish juveniles. Habitat and biology. Oregon State Library. Invasive carp have been progressing upstream since escaping into the Mississippi River in Arkansas in the 1970s. The species is somewhat sensitive to low oxygen conditions. Silver carp are phytoplanktivorous filter feeders (Ni and Jiang, 1950), although zooplankton is also ingested. Silver carp are similar to bighead carp, except for their silver color and a ventral keel that extends forward to the anterior part of the breast, almost to the gill membranes.

Bighead carp are also filter feeders, but they filter larger particles than silver carp, and in general consume a greater proportion of zooplankton in their diets than silver carp, which consume more phytoplankton.

It was introduced to the United States in 1973 by a private fish farmer in Arkansas to control algae blooms in his ponds. Potential control methods include the use of fish poisons, physical barriers, physical removal, habitat alteration, or the addition of predators, parasites, or pathogens. Thus, in some cases, blue-green algae blooms have been exacerbated by silver carp. The common carp or European carp (Cyprinus carpio) is a widespread freshwater fish of eutrophic waters in lakes and large rivers in Europe and Asia.

Silver carp are usually farmed in polyculture with other Asian carp, or sometimes with catla or other fish species. The fish feed on the small particles released from the dough ball and bump against the dough ball, with the intention of breaking off more small particles that can be filtered from the water, eventually becoming hooked on the tiny hooks. (2006). [2] Although a threatened species in its natural habitat, it has long been cultivated in China. Understanding their diet and habitat selection could be helpful for predicting their expansion and impacts in systems they invade.

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. [12] Dams that do not have navigation locks are complete barriers to upstream natural movement of silver carp, unless fishermen unintentionally assist this movement by the use of silver carp as bait. The TVA has also considered adjusting flow rates during Asian carp spawning periods, which are usually during high-water events, as Asian carp eggs are only semibuoyant and will sink to the bottom and die with low river flow.
