Habitat and Ecology [top]

Habitat and Ecology:P. midgleyi is a benthopelagic species that is most common in well-shaded, rocky pools in clear, flowing creeks, usually with sandy bottoms and little aquatic vegetation present. It occurs in small aggregations in the wild, and is believed to spawn during the middle wet season (December to January), (Allen et al. 2002).
Congregatory:Congregatory (and dispersive)

Threats [top]

Major Threat(s): The area which is inhabited by P. midgleyi is threatened by pollution from uranium mining, but this is currently believed to be under control (UNEP-WCMC 2002). There are plans for water extraction from the lower reaches of the Katherine River, but as P. midgleyi is restricted to the upper reaches of this river it is unlikely to be affected (Jenkins, pers. comm.).

Conservation Actions [top]

Conservation Actions: The catchments of the East and South Alligator rivers, and the lower reaches of the East Alligator River fall within the Kakadu National Park (IUCN Category II).
