Relevant Information:

Description: Dorsal spines (total): 2; Dorsal soft rays (total): 6 - 7; Anal soft rays: 21 - 24. High dorsal fin, starts at above the point between pectoral and pelvic fins. Colouration: Light coloured in stomach, without any spots. Edges of all fins are black. Etymology: The genus name of Tachysurus: tachys, swift; oura, tail, referring to the presumed agility of T. sinensis based on its “long and nimble” tail (translation). The specific name of vachellii: in honour of Rev. George Harvey Vachell (1799-1839), who “presented” type. Remarks: Still valid in some publications and in some online rescources as Pseudobagrus vachellii but Eschmeyer's Catalog of Fishes has Tachysurus as the current genus name with Pseudobagrus vachellii as a junior synonym.

IUCN Red List

The species has declined since the 1960's and is likely to still be declining, however the rate of this decline is unknown. More information is needed on the population size and trends, distribution, biology and potential threats for this species, it is therefore assessed as Data Deficient, but needs updating (IUCN 2012).
