Summary of InvasivenessTop of page
H. maculatus is native to China, Korea, Japan and the Amur River basin (Kottelat, 2001a). It was accidentally introduced together with Chinese carp fry from the Yangtze River, China to the USSR, and has partially displaced local species (Welcomme, 1988). H. maculatus shows more rapid growth and higher fecundity under introduced compared to native conditions (Rosenthal, 1976). Its occurrence in the Mekong tributaries in northern Laos apparently results from intentional introductions upriver in China (Kottelat, 2001b). This introduction has created a potential serious competitor and threat for the native benthic fishes (Kottelat, 2001b).

Notes on Taxonomy and NomenclatureTop of page
Hemibarbus maculatus Bleeker, 1871: type locality: China: Yangtze River; junior secondary homonym of Barbus maculates Valenciennes, in Cuvier & Valenciennes, 1842: 195, when placed in Barbus by Gunther, 1889: 224; these taxa are no longer considered congeneric and the substitute name [Barbussemibarbus Gunther, 1889: 224] is not in use, so Hemibarbus maculatus is not rejected (Kottelat, 2006).
Barbus semibarbus Günther, 1889: replacement name for Hemibarbus maculatus Bleeker, 1871 (Kottelat, 2006).
Acanthogobio paltschevskii Nikolskii, 1903:type locality: Russia: Lake Chanka at mouth of River Santacheza (Kottelat, 2006).
Hemibarbus joiteni Jordan & Starks, 1904: type locality: China: Pei Ho at Tientsin (Kottelat, 2006).
Hemibarbus longibarbis Fang, 1938: type locality: China: Kiangsi: Sau-hsui (Kottelat, 2006).
The genus Hemibarbus has been revised by Yue (1995). The species previously identified as H.maculatus is in fact an assemblage of several species and the fishes from the Xijiang basin previously referred to this species are a distinct species, H.macracanthus. Although not very detailed, the account of H. maculatus in Mai (1978) suggests that at least part of his material belong to this species. This is suggested by the information on the dorsal spine being longer than the head, which is a character distinguishing H. macracanthus from all other species of the genus. Locality data are not provided for Mai's material. The presence of the species in Vietnam in the Xijiang basin in expected, but its presence in the Hong River basin needs confirmation. Chen and Li (in Chu and Chen, 1989) record H. maculatus from several localities in Yunnan, in the Yangtze, Pearl, Hong River and Mekong basins. Their figure apparently shows a real H. maculatus but the origin of the specimen used as model is not stated; it is likely a specimen from the Yangtze basin. The identity of their material from the Hong River and Mekong basins is not known. The possibility of the presence in Vietnam of H. maculatus however should not be neglected as this species could be mixed with fry of cultivated fishes imported in the country. This is how the presence of the species is explained in the Mekong basin in Laos.
DescriptionTop of page
Vertebrae: 42-44. Both sides of the body with 7-11 large and blackish spots. Deep body with clearly convex dorsal profile. Head length shorter than body depth. Snout length shorter or equal to postorbital head length. Lips not developed, lateral lobes of lower lip narrow, without folds, the median process large and marked. Barbel length slightly thick, 1/2-2/3 of eye diameter. Dorsal spine strong, equal to head length. Origin of dorsal fin nearer the tip of snout than the caudal base (Yue, 1995). Anal fin with 6 1/2 branched anal rays; last simple dorsal ray ossified, spine-like (Kottelat, 2001a, b).

Biology and EcologyTop of page
The chromosome number of H. maculatus is 2n=50; the DNA content is half of the published value for diploid nuclei (DNA/2n: 2.30 ± 0.11 pg) (Cui et al., 1991). The DNA barcode of this species is published in Tang et al. (2011).
Reproductive Mode: dioecism, fertilization: external, reproductive guild: non-guarders open water/substratum egg scatterers. Description of life cycle and mating behaviour: Mature at 3 years of age. Spawns from May to June, with water temperatures from 19-25°C. Eggs are pasted on to underwater plants. Egg diameter is about 2 mm. Development time is about 4 days. Larvae live in the pelagic zone for the first 6 days (Baensch and Riehl, 1991).
H. maculatus mainly feeds on aquatic insects but also snails, clams (Corbicula) and small fish.

Means of Movement and DispersalTop of page
This has taken place in Asia: China, Korea, Japan and the Amur River basin (Kottelat, 2001a, b).
H. maculatus has been accidentally introduced together with Chinese carp fry from the Yangtze River, China to USSR (Welcomme, 1988). It has partially displaced local species. It shows more rapid growth and higher fecundity than under native conditions (Rosenthal, 1976).
Occurrence in the Mekong tributaries in northern Laos apparently results from introductions upriver in China (Kottelat, 2001). H. maculatus is a potential serious competitor and threat for the native benthic fishes (Kottelat, 2001a, b).
Environmental ImpactTop of page
Impact on Biodiversity
H. maculatus has been recorded to be a serious competitor to and threat for the native benthic fishes, where it is introduced (Kottelat, 2001b). When it was, for example, introduced from the Yangtze River, China in the USSR, it has partially displaced local species (Welcomme, 1988). One of the characteristics of this species that make it a successful invader is the fact that it shows more rapid growth and higher fecundity under introduced compared to native conditions (Rosenthal, 1976).
Risk and Impact FactorsTop of page Invasiveness
- Proved invasive outside its native range
- Has a broad native range
- Abundant in its native range
- Highly adaptable to different environments
- Pioneering in disturbed areas
- Tolerant of shade
- Long lived
- Has high reproductive potential
- Ecosystem change/ habitat alteration
- Modification of natural benthic communities
- Negatively impacts aquaculture/fisheries
- Reduced native biodiversity
- Threat to/ loss of native species
UsesTop of page
H. maculatus is a nutritious fish high in protein. In recent years, it has sold well in the east China (Lu et al., 2004). It is also an economically important fish in Thua Hue Orovince, Vietnam (Vo et al., 2006).
Similarities to Other Species/ConditionsTop of page
H. maculatus is especially similarity to Hemibarbus labeo. The main differences between these two species are as follows:
H. maculatus: Snout length shorter or equal to postorbital head length.
H. labeo: Snout length much longer than postorbital head length (Chen, 1998).
