Actinopterygii (ray-finned fishes) > Perciformes (Perch-likes) > Percichthyidae (Temperate perches)
Etymology: Nannoperca: Latin, nannus = small + Greek, perke = perch (Ref. 45335 ) .  More on author: Whitley .

Environment: milieu / climate zone / depth range / distribution range Ecology

Freshwater; benthopelagic; pH range: 6.0 - 6.5; dH range: 5 - 10.   Temperate; 16°C - 30°C (Ref. 2060 ); 25°S - 29°S

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Oceania: endemic in the coastal drainages of northeast and southeast Australia, from Noosa River to Richmond River (Ref. 5259 ). Also in dune lakes between the Maroochy and Noosa River systems (Ref. 2906 ), Queensland to New South Wales, Australia.

Length at first maturity / Size / Weight / Age

Maturity: L m 2.9 , range 2 - 2.99 cm
Max length : 7.5 cm SL male/unsexed; (Ref. 7276 ); common length : 4.0 cm SL male/unsexed; (Ref. 44894 )

Biology     Glossary (e.g. epibenthic)

Inhabits ponds, dune lakes and creeks, usually among aquatic weeds (Ref. 6398 ). Lives in swamps with prolific sedge growth, gently flowing streams and dune lakes in areas of coastal heathland (wallum). Water is often darkly tannin-stained and acidic (pH 5.4-6.5) with temperature range from 12° to 28°C (Ref. 44894 ). Feeds primarily on aquatic insects and their larvae (Ref. 5259 ). Also consumes microcrustaceans and algae. Breeding season extends from October to May, when water temperatures rise above 20°C. The breeding habits and biology are similar to other nannopercids, but this species takes only 4-5 months to attain sexual maturity (Ref. 44894 ). Aquarium conditions: pH=7.2, H=8, 26°C water temperature, egg layer, plant and rock cover, peaceful community fish (Ref. 6398 ).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

During the breading season, N. oxleyana displays sexual dichromatism, with males showing more intense changes (Ref. 74347 ). Males display a darkening of the dorsal, anal and pelvic fins and red colouration of the body and caudal fin (Ref. 74352 ). Serial spawner (Ref. 74347 ).

Estimates based on models

Phylogenetic diversity index (Ref. 82805 ):  PD 50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.01096 (0.00425 - 0.02829), b=3.05 (2.83 - 3.27), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic Level (Ref. 69278 ):  3.2   ±0.40 se; Based on food items. Resilience (Ref. 120179 ):  Medium, minimum population doubling time 1.4 - 4.4 years (Fec=225-270). Vulnerability (Ref. 59153 ):  Low vulnerability (13 of 100) .
