Common carp by Alexander Francis Lydon. The type subspecies is Cyprinus carpio carpio, native to much of Europe (notably the Danube and Volga rivers). [2] [4]The subspecies Cyprinus carpio haematopterus (Amur carp), native to eastern Asia, was recognized in the past, [4] but recent authorities treat it as a separate species under the name Cyprinus rubrofuscus.
The common carp (Cyprinus carpio) is originally from Central Europe. [49] Several carp species (collectively known as Asian carp) were domesticated in East Asia. Carp that are originally from South Asia, for example catla (Gibelion catla), rohu (Labeo rohita) and mrigal (Cirrhinus cirrhosus), are known as Indian carp. Their hardiness and ...
During the winter months, houseplants receive less natural light and they don’t grow as quickly. As a result, plants generally don’t need much or any fertilizer in winter. But this can vary ...
Koi in Yu Garden, Shanghai. The Amur carp is a hardy fish, and koi retain that durability. Koi are coldwater fish, but benefit from being kept in the 15–25 °C (59–77 °F) range, and do not react well to long, cold, winter temperatures; their immune systems are very weak below 10 °C (50 °F).
Naked carp reach a maximum length of 48 cm (1.57 ft) and are typically 300–500 g (0.66–1.10 lb) at reproductive age. [ 2 ] [ 5 ] They feed mostly on benthic zooplankton about 2 m (6.6 ft) below the surface, though they also feed on other aquatic invertebrates. [ 8 ]
Some cyprinids, such as the grass carp, are specialized herbivores; others, such as the common nase, eat algae and biofilms, while others, such as the black carp, specialize in snails, and some, such as the silver carp, are specialized filter feeders. For this reason, cyprinids are often introduced as a management tool to control various ...
They also eat a high-fiber diet in the winter, which primarily consists of twigs and bark on trees and shrubs. Plus, they reduce their movement and metabolism, lowering their nutritional needs.
Grass carp require long rivers for the survival of the eggs and very young fish, and the eggs are thought to die if they sink to the bottom. [6] Adult grass carps feed primarily on aquatic plants, both higher aquatic plants and submerged terrestrial vegetation, but may also eat detritus, insects and other invertebrates.
