Strongylura kreffti

A long slender fish with long jaws of equal length containing rows of sharp pointed teeth. Silver in colour with an olive-green tint. Grows to 85 cm but more common 30-40 cm. Some populations known to reproduce entirely in freshwaters (including within Ross River weirs) but upstream movement from lower estuarine reaches and between river channel and floodplain habitats also observed. Known to occur in Saltwater Creek, the Lower Burdekin catchment, Ross River basin and a number of creeks in the Haughton River basin. Distribution within distributary stream floodplain habitats of the lower Burdekin has been reduced due to habitat and water quality impacts.

Acknowledgements

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 Norther 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)
