Environment: milieu / climate zone / depth range / distribution range Ecology

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Asia: China, Japan and Korea between the rivers Zhujiang (Pearl river) and Heilongjiang (River Amur). Europe: occurrence in the Russian part of Amur basin is probably the result of introductions. Many authors refer to this species by its old name Macropodus chinensis, but see Ref. 42237.

Short description Morphology | Morphometrics

Dorsal spines (total): 12 - 19; Dorsal soft rays (total): 5-9; Anal spines: 15-20; Anal soft rays: 7 - 15; Vertebrae: 27 - 29. Caudal fin rounded; lower margin of preorbital weakly serrated, embedded under skin (Ref. 559). Stripe crossing eye not connecting spot on posterior projection of opercle with eye; posterior dorsal-fin rays filamentous behind vertical of posterior anal-fin rays in adults; 6-13 gill rakers on ceratobranchial of first arch; posterior tip of margin of scales on body not darker than scales (Ref. 42924).

Obligate air-breathing (Ref. 126274); Biology similar to Macropodus opercularis. Reported to be well-adapted to low winter temperatures (4-25°C); adults and juveniles (about 1.5 cm SL), are sometimes active under ice cover (E. Willems pes.comm. 11/12).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01514 (0.00703 - 0.03260), b=2.92 (2.73 - 3.11), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.5 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
