Grass carp grow large and are strong fighters when hooked on a line, but because of their vegetarian habits and their wariness, they can be difficult to catch via angling. [18] The IGFA World record for a grass carp caught on line and hook is 39.75 kg (87.6 lb), caught in Bulgaria in 2009. [ 19 ]
Grass carp require long rivers for the survival of the eggs and very young fish, and they have become very abundant in the large rivers of the central United States. [18] Grass carp are strong fighters on a rod and reel, but because of their vegetarian habits and their wariness, they can be difficult to catch. [19] Chumming with corn adds to ...

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 ...
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.
Fish used in this system include catla and silver carp (surface feeders), rohu (a column feeder), and mrigal and common carp (bottom feeders). Other fish also feed on the excreta of the common carp, and this helps contribute to the efficiency of the system which in optimal conditions produces 3000–6000 kg of fish per hectare per year. [36]
Asian carp is an informal grouping of several species of cyprinid freshwater fishes native to Eurasia, commonly referring to the four East Asian species silver carp, bighead carp, grass carp (a.k.a. white amur) and black carp (a.k.a. black amur), [note 1] which were introduced to North America during the 1970s and now regarded as invasive in the United States.
The bighead carp (Hypophthalmichthys nobilis) is a species of cyprinid freshwater fish native to East Asia, and is one of several Asian carps introduced into North America.It is one of the most intensively exploited fishes in fish farming, with an annual worldwide production of over three million tonnes in 2013, principally from China.
