Etymology: Ctenopharyngodon: Greek, kteis, ktenos = comb + Greek, pharyngx = pharynx + greek, odous = teeth (Ref. 45335)idella: From the words cteno, meaning comb; pharyngodon, pharyngeal teeth (referring to the corrugate or comb-like cutting surfaces of the pharyngeal teeth); and idella (derived from ideo), meaning distinctive (Ref. 10294).

; acqua dolce; salmastro benthopelagico; potamodromo (Ref. 51243); distribuzione batimetrica 0 - 30 m (Ref. 6898). Subtropical; 0°C - 35°C (Ref. 52059); 50°N - 23°N, 100°E - 142°E (Ref. 48)

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 Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 10 - 11; Spine anali: 0; Raggi anali molli: 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).


Body shape (shape guide): fusiform / normal.

Biologia     Glossario (es. 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 Maturità | Riproduzione | Deposizione | Uova | Fecundity | Larve

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

Estimates based on models

Phylogenetic diversity index (Fonte Biblio. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00933 (0.00810 - 0.01075), b=3.09 (3.05 - 3.13), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Fonte Biblio. 69278):  2.0   ±0.00 se; based on food items.
Resilienza (Fonte Biblio. 120179):  Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (K=0.13-0.19; tm=2-10; tmax=21; Fec=50,000).
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (69 of 100). 🛈
