Porochilus rendahli

The colour of this catfish varies from a uniform or mottled grey to pale yellowish-brown, usually with a golden sheen. Have dorsal and pectoral spines capable of inflicting painful wounds. Distinguished from other Catfish by its concave head. Grows to a maximum length of 24 cm. Broadcast spawners with demersal eggs. Commonly found in submerged macrophyte beds. Distributed throughout the Burdekin Basin (Upper, Lower and Bowen Catchments). Believed to also occur in the Ross River basin, Haughton River basin and Saltwater Creek of the Don River basin.


Much of the information about fish species and their distribution in the Burdekin Dry Tropics region presented throughout this Wiki is based on the work of Pusey (2005). The Australian Centre for Tropical Freshwater Research (ACTFR) also provided access to their Northern Australian Fish (NAF) database (in press), which contains the most current available fish survey data for tropical Australia. Allan Webb also from ACTFR provided information of the expanding list of exotic fish species recorded from the immediate Townsville region principally the Ross River. Additional information about species distribution is the authors experience (principally Jim Tait) and knowledge of the region. Descriptions of species are based on Allen et. al. (2002) and Pusey et. al (2004) with additional detail and comments by the authors of the Fish Passage Study.

Fish illustrations and mapping by Jason Carter. Illustrations have been drawn from specimens and photographs and after other illustrations, in particular Swainston and Ruse (in Allen 1997) and Pusey (in Pusey et. al. 2004)
