Redigobius bikolanus

Grows to a maximum size of 3.8 cm. Cylindrical body with a small mouth. Body is tan or light grey with dark brown blotches on sides. A prominent diagonal band extends across the cheek from lower eye. A second equally distinctive dark bar on the dorsal fin runs down the body to the belly. Demersal adhesive eggs. Reproductive strategy not well known but distribution below major barriers suggests species like many other gobies is dependent upon a marine larval phase. Recorded within the Lower Burdekin catchment (both above and below Clare Weir) and the Bowen River, and is expected to occur throughout the Black River basin, Ross River basin, Haughton River basin and Don River basins. Absent from the Upper Burdekin catchment.


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)
