The golden perch (Macquaria ambigua) is a medium-sized, yellow or gold-coloured species of Australian freshwater fish found primarily in the Murray-Darling River system, though a subspecies is found in the Lake Eyre-Cooper Creek system, and another subspecies, suspected to be ancestral to all other populations, is found in the Fitzroy River system in Queensland. [3]
Some workers have found that the genus Macquaria is polyphyletic and that the two catadromous species Macquaria colonorum and M. novemaculeata are not the closest relatives of the other two species in the genus and are placed in the genus Percalates in the monotypic family Percalatidae These authors also found that the Percichthyidae and the Percalatidae were part of one of three cladea within ...
The Murray cod is the apex aquatic predator in the rivers of the Murray-Darling basin, [3] and will eat almost anything smaller than itself, including finned fishes such as smaller Murray cod, golden perch, silver perch, bony bream, eel-tailed catfish, western carp gudgeon, and Australian smelt and introduced fish such as carp, goldfish, and ...
6 lb oz perch caught by angler known as Bill from River Thames in March 2014. Assumed reason is lack of independent witnesses. 70 lb pike (the largest ever) found dead at River Endrick/Loch Lomond in 1934. [229] Not caught by rod and line. 5 lb 2 oz rudd caught by Adrian Cannon from a fenland drain 2012. [230] No independent witnesses.
Prior to that, Australian bass and estuary perch were in a separate genus, Percalates. (The generic name Percalates is a compound of the generic names Perca and Lates, and arose from an early, erroneous taxonomic belief that Australian bass were an old world perch related to barramundi (Lates calcarifer)).
The age of the perch is highly based on the condition of the lake. Most research has shown the maximum age to be approximately 9–10 years, with a few living past 11 years. Yellow perch have been proven to grow the best in lakes where they are piscivorous due to the lack of predators. Perch do not perform well in cold, deep, oligotrophic lakes ...
Silver perch are not a "true" perch of the genus Perca, but are instead a member of Terapontidae or 'grunter' family. They are the largest member of the Terapontidae, capable of growing in excess of 60 cm (24 in) and close to 8 kg (18 lb), but today wild river specimens are typically 30–40 cm (12–16 in) and 1.0–1.5 kg (2.2–3.3 lb).
The 5th Edition of Fishes of the World classifies the Percidae into five subfamilies [3] and Fishbase recognises 239 species in 11 genera. [4] [1] [6] Subfamily Percinae Rafinesque, 1815. Genus Perca Linnaeus, 1758; Subfamily Acerinae Bleeker, 1858. Genus Gymnocephalus Bloch, 1793; Subfamily Percarininae Gill, 1861. Genus Percarina Nordmann, 1840
