Justification:
A common species, although its population status is unknown. It is restricted to two lakes (estimated extent of occurrence (EOO) <5,000 km², area of occupancy (AOO) <500 km²) which are suffering from eutrophication, loss of reed beds due to land reclamation, and lake level decline due to water extraction. The species distribution is treated as a single location due to the connection between the two lakes.

Habitat and Ecology
[top]
| Habitat and Ecology: |
A lacustrine species. It is the smallest freshwater European teleost at maturity: 18 mm with a maximum length of 25 mm. It is a semelparous species dying just after spawning. The males provide parental care.
|
| Systems: |
Freshwater |
| Major Threat(s): |
Water pollution, water extraction (lake level now fluctuates), and potentially habitat impacts from bottom trawling.

Conservation Actions
[top]
| Conservation Actions: |
The integrated water resources management plan for the Trichonis Lake (developed in the framework of the Life - Nature '99 project entitled: 'Actions for the preservation of Calcareous fens in Trichonis lake') should be implemented in the area aiming to eliminate the present high water level fluctuations in the lake on both annual and monthly basis. This will decrease the environmental impacts from the water abstractions for irrigation during the dry period and will facilitate preservation of the ecologically important habitats, in the broader area.
