[2] The value of bighead carp as a food fish has caused it to be exported from its native China to more than 70 other countries, where it has invariably escaped or been intentionally released to the wild.It also has been introduced into most of the Indian subcontinent (India, Pakistan, Bangladesh) and most Southeast Asian countries, as well as to lakes in western China where it is not native.Bighead carp are not always considered undesirable, invasive species where they are introduced outside their native range, and they continue to be stocked in some water bodies to support commercial fisheries.[citation needed] In the United States, a limited consumer market has developed for bighead carp, particularly in ethnic communities, and they are farmed in ponds for this purpose.[citation needed] Although the bighead carp is enjoyed in many parts of the world, it has not become a popular food fish in North America.The Louisiana State University Agricultural Research and Extension Center has a series of videos showing how to prepare the fish and deal with these bones.[citation needed] Although bighead carp reach large size, they are difficult to capture with a rod and reel because of their filter-feeding habits.
