Type locality of Dules haswellii: Rockingham Bay, Queensland (Ref. 41640). Known from Cape York to Maroochy River, Queensland (Ref. 44894). Known from Mulgrave and South Johnstone rivers, Wet Tropics, Northern Queensland (Ref. 40054). Jungle perch have declined in the southern part of their range in Queensland. Most likely due to dams and weirs disrupting their diadromous life history pattern and because of altered flows. Jungle perch have been recorded as far south as the Richmond River in New South Wales Australia. Only small remnant populations remain in the southern part of their range in perennial undammed streams. Some further information on regulations for Kuhlia rupestris. A bag limit of one fish applies in Queensland. A maximum size limit of 35 cm has been set to protect breeding females. Catch and release fishing is encouraged. Fish as large as 5 kg have been reported in remote areas. (Michael Hutchison, pers. Comm., 2002). Also Ref. 2847, 7300, 33390.
