Assessment Information [top]

Red List Category & Criteria: Endangered   A2ce; B1ab(i,ii,iii,iv,v)+2ab(i,ii,iii,iv,v)   ver 3.1
Year Published: 2006
Assessor/s: Crivelli, A.J.
Reviewer/s: Barbieri, R. & Kottelat, M. (Mediterranean Workshop, Dec. 2004)
Justification:
There is an inferred 50% population decline in the last 10 years based on decline in area of occupancy (AOO) (the river has dried out in places and there is no potential for recolonisation as the fish is sedentary in habit), and an observed massive loss of fish as a result of pollution from the orange juicing factory. The estimated extent of occurrence (EOO) is less than 5,000 km², and the estimated AOO is less than 500 km². It is restricted to a single location, and experiences an ongoing decline in AOO, habitat quality, the number of subpopulations, and number of mature individuals.
History:
1996 – Vulnerable (Baillie and Groombridge 1996)
1996 – Vulnerable
