Red List Category & Criteria: Critically Endangered (Possibly Extinct) B1ab(i,ii,iii,iv) ver 3.1

Acanthobrama centisquama species was restricted to Amik Lake (Turkey) and al-Gab Lake (Syria), both in the Asi (Orontes) drainage. It is unknown if this species still exists as it has not been found since the early 20th century. It seems to be most likely extinct, however there is still a chance that A. centisquama has survived in Lake Gölbasi (12 km², in Asi drainage), which is impacted by pollution and water abstraction, and is the only remaining relict of Lake Amik. However, no detailed survey has been undertaken. If the species is not yet extinct, it must be at the very border of extinction. It is therefore assessed as Critically Endangered (Possibly Extinct).
Date last seen: early 20th century

Population [top]


This species is possibly already Extinct. In modern times it is known only from Amik Lake (Turkey). This lake was drained between the 1940s and 1970s. Scales and pharyngeal teeth also known from Lake al-Gab in Syrian Asi drainage which has been drained much earlier. There is still a chance that A. centisquama has survived in Lake Gölbasi, which is the only remaining relict of Lake Amik, but no detailed survey has been undertaken.

Current Population Trend:Unknown
Additional data:

Habitat and Ecology [top]

Habitat and Ecology:This is a lacustrine species restricted to shallow and marshy lakes.
Continuing decline in area, extent and/or quality of habitat:Yes
Movement patterns:Not a Migrant

Threats [top]

Major Threat(s): The species might be still present in Lake Gölbasi. This lake is polluted, water is abstracted from the lake as well as from the groundwater and climate change induced less rainfall in the area combine to a very critical situation for this small lake.

Conservation Actions [top]

Conservation Actions: No conservation actions are known to be in place. There is an urgent need to conduct some fieldwork to find out if the species is still present in Lake Gölbasi to allow conservation planning and ex-situ conservation.
