Grass carp inhabit lakes, ponds, pools and backwaters of large rivers, preferring large, slow-flowing or standing water bodies with abundant vegetation. [5] In the wild, grass carp spawn in fast-moving rivers, and their eggs, which are slightly heavier than water, develop while drifting downstream, kept in suspension by turbulence.
Cyprinus / s ɪ ˈ p r aɪ n ə s / is the genus of typical carps in family Cyprinidae.Most species in the genus are of East Asia origin with only the common carp (C. carpio) in Western Asia and Europe; this invasive species has also been introduced to many other regions around the world. [1]
Several cyprinids have been introduced to waters outside their natural ranges to provide food, sport, or biological control for some pest species. The common carp (Cyprinus carpio) and the grass carp (Ctenopharyngodon idella) are the most important of these, for example in Florida.
Cypriniformes is an "order-within-an-order", placed under the superorder Ostariophysi—which is also made up of cyprinid, ostariophysin fishes. The order contains 11–12 families (with some authorities having listed as many as 23), [ 2 ] over 400 genera, and more than 4,250 named species ; new species are regularly described, and new genera ...
Cyprinus carpio carpio is a subspecies of the common carp that is commonly found in Europe. They are native to much of Europe (notably the Danube and Volga Rivers) and can also be found in the Caucasus and Central Asia. [2] Mitochondrial DNA analysis shows a difference between C. carpio carpio and Cyprinus rubrofuscus. [3]
In biology, taxonomic rank (which some authors prefer to call nomenclatural rank [1] because ranking is part of nomenclature rather than taxonomy proper, according to some definitions of these terms) is the relative or absolute level of a group of organisms (a taxon) in a hierarchy that reflects evolutionary relationships.
Grass carp Ctenopharyngodon idella: Cultivated 6,068,014 China is the major producer of the grass carp, which grows quickly and requires fairly little dietary protein. Low-cost feed such as grain processing and vegetable oil extraction by-products, terrestrial grass, and aquatic weeds, allows the grass carp to be produced cheaply. [4]
Ecological yield is the harvestable population growth of an ecosystem. It is most commonly measured in forestry : sustainable forestry is defined as that which does not harvest more wood in a year than has grown in that year, within a given patch of forest .
