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

Asia: Eastern Asia and Taiwan. Introduced into eastern China, the Korean Peninsula and Japan which for a time were considered as the native range of the species due to an effective colonization of the natural waters. At least one country reports adverse ecological impact after introduction (Ref. 1739).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00918 (-0.15001 - 0.16837), b=3.07590 (2.98959 - 3.16221), based on LWR estimates for this family-BS (Ref. 93245).

Trophic Level (Ref. 69278): 2.7 ±0.2 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.82-2.15; Fec assumed < 100).

Vulnerability (Ref. 59153): Low vulnerability (16 of 100) .

Price category (Ref. 80766): Unknown.
