Craterocephalus centralis Crowley & Ivantsoff 1990b
Finke hardyhead

ATHERINIDAE Hardyheads or silversides



Size

Recorded to 64mm (2.6in) SL.

Conservation Status

Listed as Restricted by the Australian Society for Fish Biology.

Distribution & Abundance

Restricted to the Finke River and its associated tributaries. They are generally abundant within this restricted range.

Habitat & Ecology

They occur in relatively permanent waterholes, either in open water or amongst aquatic vegetation. Their diet is probably omnivorous. Finke hardyheads would have broad temperature and salinity tolerances.

Reproduction

Nothing is known of their breeding biology. Like most craterocephalids they probably spawn during the warmer months, laying 20 or more eggs daily.

Threats

The only present threat to this species is it's restricted range. The majority of relatively permanent water exists within National Parks or conservation reserves. Despite this, the introduction of additional fish species remains a potential threat.

Conservation Actions

None are presently undertaken.

Conservation Recommendations

It would be beneficial if monitoring for the presence of introduced species is done on a regular basis.
