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]

Description

The largest adult measured is about 36 centimetres (14 in) long.[2] Usually, adults grow up to 17 centimetres (6.7 in) long.[2]

Ecology

Diet

The congoli feeds on insects, fish, crustaceans, worms, mollusks, and other invertebrates.[2]

Behavior

Congolis are ambush predators that usually bury themselves in the substrate.[2] During the time period between late April and August, it migrates south to estuaries to reproduce.

Importance to humans

Occasionally, this fish is caught for food. It shows a minor importance to commercial fishing.[2] The congoli is also caught by anglers.

Reproduction

Adults migrate south downstream to reproduce. It takes place between late April and August.[2]
