(EXOTIC SPECIES)

Oreochromis mossambicus

Tilapia are part of the Cichlidae family. Two species have established in Queensland - the Mozambique mouthbrooder (Oreochromis mossambicus) and the black mangrove cichlid (Tilapia mariae). O.mossambicus can grow to more than 36cm and can live up to 13 years. They have pale olive to silver-grey bodies with two to five indistinct dark blotches on the side. Adults move to floodplain habitats during high water level periods. Young actively disperse to new habitats. O.mossambicus have been recorded within the Ross River basin, Black River basin (Bluewater Creek, Deep Creek, Black River) and Upper Burdekin catchment (Burdekin River and Keelbottom Creek).

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 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)
