Silver perch fish is a fish that has been around for some time now. It is not well known in the US but is a famous fish among Australians for its high-grade taste and its high protein content. Many are not aware that this fish is found in the US in aquariums mostly. Well, this is not surprising considering how the commercial fishing of this fish is banned from the Great Lakes region of the US.

The silver perch fish, Bairdiella chrysoura, is a species of fish belonging to the family Terapontidae. It is found in the tropical and subtropical waters of eastern Australia, from Narrabri in northern New South Wales to northern Queensland, including the Whitsunday Islands. They reach a maximum length of 20 cm (8 in). The species is sometimes referred to as the silver trout.

The silver perch fish is unusual (at least among perciformes fish) in that it possesses a pair of dorsal fins, one of which is soft and flexible.

The species was once widespread on the southern Australian mainland and Papua New Guinea but has recently declined in many areas. It is now restricted to about a dozen areas in southern and eastern Australia (including Kangaroo Island and Tasmania), as well as two locations in New Guinea (Woodlark Island and the Huon Peninsula). It is widespread in Tasmania, but only locally distributed throughout the rest of the country.

They are found in many freshwater lakes, rivers, and streams across eastern Australia. Their habitat ranges from the tropical north of Australia to the temperate regions of Tasmania. Silver Perch are also found in the coastal waters of Queensland and New South Wales. They are found in lakes, rivers, and coastal waterways that have at least some vegetation. They are rarely found in very clear water.

The Murray-Darling River system was once home to many silver perch. As a result, there are now only a few of them in many former habitats or they have disappeared completely.

Several anabranches and tributaries of the Murray River flow downstream from the Yarrawonga weir, providing the population with a secure and self-sustaining environment.

Size and weight

The silver perch is a small-sized fish with an average length of 50 cm (20 in) and a weight of around 1.2 kg (2.6 lbs). The fish has a moderately long, slender body and a forked tail. The mouth is large, with small teeth and a protruding lower jaw. The color is silvery, with irregular vertical bars, the fins being yellowish. The pectoral fins have strongly concave rear margins.

Feeding

In addition to small crustaceans, silver perch eat bristle worms.

Reproduction and life cycle

Spring is the best time to observe spawning along the eastern shore of the Bay. Throughout their life cycle, larvae and young waterfowl move upstream into fresher water. Eventually, they return to the Bay, congregating in shallows with higher salinities near bay grass beds.

  • Sand perch is another name for silver perch.
  • This species belongs to the Terapontidae/drum family, along with spots, weakfish, red drums, black drums, and spotted seatrouts. With the help of special muscles in their swim bladders, drums can make a loud croaking or drumming noise. Most of the drums are in the Atlantic region.
  • It is easy to confuse them with white perch. Silver perches can be distinguished by their yellowish fins and by their slightly pointed, not forked, tail.
