The bighead carp (Hypophthalmichthys nobilis) is a species of
Bighead carp, together with Black carp, Silver carp, and Grass carp, make up the culturally important "four famous domestic fishes" used in polyculture in China for over a thousand years. It is widely farmed for food and chinese medicine.[3]
Description
The bighead carp has a large, scaleless head, a large mouth, and eyes located very low on the head. Adults usually have a mottled silver-gray coloration. It is a large fish; a typical length is 60 cm (2 ft), and maximum observed size of 146 cm (4 ft 9 in) and 40 kg (88 lb).[4]
Distribution
Bighead carp are native to large rivers and are associated with floodplain lakes of eastern Asia. Their range extends from southern
Aquaculture
The bighead carp has a very fast growth rate, which makes it a lucrative and important aquaculture fish, having the fifth-highest production (7.5%) of all cultured freshwater fish worldwide.[2] Its production grew from just 15,306 tonnes in 1950 to 3,059,555 tonnes in 2013, most of the growth being in China.[2]
Invasive species
The value of bighead carp as a
Bighead carp are considered a highly destructive
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. The live or very freshly killed fish is most lucrative. Because of this, bighead carp are often transported live, and may be a high risk factor for the eventual spread of the fish, either through release by the end purchaser, or through escape during transport. Another potential avenue for unintentional spread of bighead carp is through use as live fishing bait.[5]
Communities are attempting to contain the spread of the extremely invasive bighead carp.
Live bighead carp are also banned from sale in
Killed carp can still be sold in stores, but Asian retailers and consumers prefer live over killed fish. Killed carp is cut into pieces: head, fillet and tail.[citation needed]
Meat
Singapore
In Singapore, it is known by the Chinese name 松鱼 (sōng yú). The head of the bighead carp is particularly prized in Singapore, and is usually steamed whole.[citation needed]
North America
Although the bighead carp is enjoyed in many parts of the world, it has not become a popular food fish in North America. Acceptance there has been hindered in part by the name "carp", thus popular association with the common carp, which is not a generally favored foodfish in North America. The flesh of the bighead carp is white and firm, and not similar to that of the common carp, which is darker and richer. Bighead carp flesh does share one unfortunate similarity with common carp flesh - both have intramuscular bones within the filet. However, bighead carp captured from the wild in the United States tend to be much larger than common carp, so the intramuscular bones are also larger and less problematic. 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]
Sport fishing
Although bighead carp reach large size, they are difficult to capture with a rod and reel because of their filter-feeding habits. They may be captured by the "suspension method" used to catch silver carp, or where legal, by snagging with a weighted treble hook through the water. When bowfishing, Bighead carp cannot be shot in the air like silver carp, because they do not jump out of the water when startled by moving boats like the silver carp do. However, they often feed near the surface, where they can be shot by bowfishers, for whom they are popular targets.[citation needed]
