Summary of Invasiveness

Top of page

M. anguillicaudatus, the oriental weatherloach, is native to Asia but has been introduced into a number of other countries via escapes from fish farms and from its use as live bait by anglers. M. anguillicaudatus has negative impacts on native fish due to predation and transmission of disease.

Description

Top of page

The body of M. anguillicaudatus is mottled with darker greenish-grey to dark brown coloured markings, against a yellow-brown to brown background (FishBase, 2004). This species is recognised by its cylindrical body, five pairs of barbels around its mouth and its single short-based dorsal fin (Australian Museum, 2003). Dorsal view shows the male with larger pectoral fins and the female with fuller abdomen (Yamamoto and Tagawa, 2000). Mature males are easy to identify because the second pectoral ray is long and thick (Australian Museum, 2003). The pectoral fin is triangular rather than rounded. It has conspicuous adipose crests along the ventral and dorsal mid-lines of the caudal peduncle and suborbital spine is hidden in the skin (Kottelat, 1998). The lateral line is very short, not exceeding the length of the pectoral fin (Jayaram, 1981). It grows to a total length of 24.8 cm (Berg, 1964).

Distribution

Top of page

M. anguillicaudatus is found in Myanmar and northeastern Asia and southward to Central China. This species has proved successful in the aquarium fish trade and has also been introduced to other countries (Welcomme, 1988). At least one country has reported adverse ecological impact after introduction (FishBase, 2004).

Impact on Biodiversity

This species can impact native species through direct predation and through transmission of diseases (Logan et al., 1996). M. anguillicaudatus are of special concern because they possess many of the characteristics of previous successful invaders. They have broad tolerance for physiological parameters, low vulnerability to predation, a flexible diet, and a high reproductive potential (Logan et al., 1996).

Risk and Impact Factors
