portusjacksoni
Portusjacksoni is a species of freshwater fish belonging to the family Percichthyidae, commonly known as temperate perches. This species is native to the freshwater systems of southeastern Australia, specifically found in the Murray-Darling basin and coastal rivers of New South Wales and Victoria. Portusjacksoni typically inhabits slow-moving rivers, billabongs, and impoundments, often preferring areas with submerged vegetation and snags. They are carnivorous fish, feeding on a variety of smaller fish, crustaceans, and insects. The adult fish can reach sizes of up to 60 cm in length, though average sizes are considerably smaller. Their coloration is generally olive-brown to grey, with darker mottling along their flanks. Portusjacksoni is a popular target for recreational anglers due to its fighting qualities and is also commercially fished in some areas. Conservation status varies by region, with some populations considered stable while others may face pressures from habitat degradation and competition with introduced species. Identification can sometimes be confused with other closely related species within the temperate perch family, requiring careful examination of fin ray counts and body proportions.
