Etymology: Ctenopharyngodon: Greek, kteis, ktenos = comb + Greek, pharyngx = pharynx + greek, odous = teeth (Ref. 45335);  idella: Cteno=comb; pharynx=throat; odon=tooth (in reference to its comblike pharyngeal teeth); and idella: presumably derived from the Greek idios, distinctive or peculiar (Ref. 79012).

Asia: Eastern China and Russia (Ref. 48) in eastern Siberia, Amur River system (Ref. 1441). Widely transported around the world (Ref. 7248). Persists only in Europe by stocking (Ref. 59043). Introductions often brought with it the parasitic tapeworm Bothriocephalus opsarichthydis (synonym of B. acheilognathi) (Ref. 12217). Several countries report adverse ecological impact after introduction.

Short description Khóa để định loại | Hình thái học | Sinh trắc học

Các tia vây lưng cứng (tổng cộng) : 0; Các vây lưng mềm (tổng cộng) : 10 - 11; Tia cứng vây hậu môn: 0; Tia mềm vây hậu môn: 10 - 14. Diagnosis: No barbels; snout very short, its length less than or equal to eye diameter; postorbital length more than half head length (Ref. 4967). 18 soft rays for caudal fin (Ref. 40476). Diagnosed from rather similar species Mylopharyngodon piceus by having the following characters: body olive to brassy green above, silvery white to yellow below; body cylindrical; pharyngeal teeth laterally compressed, serrated, with a groove along grinding surface, usually in two rows, 2,5-4,2 (Ref. 59043).

Sinh học     Tự điển (thí dụ epibenthic)

Adults occur in lakes, ponds, pools and backwaters of large rivers (Ref. 5723), preferring large, slow-flowing or standing water bodies with vegetation (Ref. 52193). Tolerant of a wide range of temperatures from 0° to 38°C, and salinities to as much as 10 ppt and oxygen levels down to 0.5 ppm (Ref. 52193). It feeds on higher aquatic plants and submerged grasses; takes also detritus, insects and other invertebrates. One of the world's most important aquaculture species and also used for weed control in rivers, fish ponds and reservoirs (Ref. 9987). Spawn on riverbeds with very strong current (Ref. 30578). Utilized also fresh and eaten steamed, pan-fried, broiled and baked (Ref. 9987). Considered as a pest in most countries because of the damages made to submerged vegetation (Ref. 43281).

Life cycle and mating behavior Maturities | Sự tái sinh sản | Spawnings | Egg(s) | Fecundities | Ấu trùng

Spawns in gravel bottomed areas of rivers (Ref. 48). Eggs are pelagic and hatch while drifting downstream in 2-3 days (Ref. 59043).
