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

Freshwater; benthopelagic. Temperate; 5°C - 20°C (Ref. 2060)

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

Oceania: endemic to south-eastern Australia, including Tasmania (Ref. 5259). Mictochodrial 12S rRNA sequences support that G. marmoratus complex consists of two northern and southern forms (Ref. 54370).

Size / Weight / Age

Maturity: L_m ? range ? - ? cm
Max length : 60.0 cm TL male/unsexed; (Ref. 5259); common length : 30.0 cm TL male/unsexed; (Ref. 5259)

Lives in clear, flowing streams with abundant cover (Ref. 5259, 44894). Prefers streams with gravel bottoms and abundant snags. Also occurs in lakes and reservoirs (Ref. 5259). Tolerant of slightly brackish conditions (10 p.p.t.) in the tidal reaches of rivers, and a temperature range of 5°-25°C. Home-ranging; remaining within about a 20-30 meters stretch of water throughout the life span (Ref. 44894). Feeds on insects, crustaceans and small fishes (Ref. 5259) ; also on mollusks (Ref. 2156). The spawning season runs from November to January. A popular angling species in the south, but large fish are rare. Highly susceptible to overfishing, due to its home-ranging behavior and low fecundity (Ref. 44894). Flesh is oily and not very good eating.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01072 (0.00408 - 0.02815), b=3.01 (2.79 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.60 se; based on food items.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (44 of 100).

Price category (Ref. 80766): Unknown.
