Justification: Austrolebias cinereus meets the criteria for Critically Endangered because it has an extent of occurrence and area of occupancy <10 km² (total pond area is approximately 10,000 m²), the species is known only from one location (a temporary pond in the lower Rio Uruguay basin), and the population is threatened by habitat loss and degradation from local industry development and tourist developments. This assessment was based on information from literature and the Facultad de Ciencias Fish Collection (Uruguay). |
|
| Range Description: | A. cinereus is known from a temporary pond in the lower Rio Uruguay basin (Department of Colonia). Its total range area is approximately 10,000 m². |
| Countries: |
Native:
Uruguay
|
| Population: | The total population occurs in one small, temporary freshwater pond. Population size is unknown. |
| Population Trend: |
Unknown
|
| Habitat and Ecology: | A. cinereus is an annual fish. It has a characteristic annual life cycle with diapausing embryos developed inside drought resistant eggs that inhabit temporary ponds. |
| Systems: | Freshwater |
| Major Threat(s): | The main known threat to this species is habitat degradation from local industry development (e.g., meat processing plant, golf field), and being located in an area that has high urban pressures. The location is a site for tourist developments, which may cause environmental modification in the near future. Non-regulated collection by aquarists may also be a potential threat to the remaining population. |
| Conservation Actions: | Enforced legal protection of this species' habitat is needed; control mechanisms such as protection laws and their true enforcement are lacking in Uruguay and are urgently needed. Nowadays, aquarists from neighbouring countries and Europe freely collect this species without any legal controls. Due to their extremely limited range and few known localities, the assessors recommend that, with the exception of justified scientific sampling, the collection of this species should be prohibited. |
