Pseudaphritis urvillii is the only species of fish in the family Pseudaphritidae and the genus Pseudaphritis. It is known also as the catadromous icefish, the tupong[1] or even more commonly as the congolli.
Distribution and habitat
Pseudaphritis urvillii is found in fresh, brackish, and marine waters around south eastern Australia including Tasmania.[2] It lives mostly in sluggish estuaries and streams. Water temperatures in its habitat range from 5 to 20 °C (41 to 68 °F). This fish will inhabit areas with log snags, over hanging banks, and leaves that fell into the water. Between late April and August, it migrates south to estuaries to breed.[2]
