Australia country information

Common names: Golden Galaxias, Golden mountain trout, Saddled galaxias
Occurrence: endemic
Salinity: freshwater
Abundance: abundant (always seen in some numbers) | Ref: Hardie, S., 2003
Importance: | Ref:
Aquaculture: | Ref:
Regulations: | Ref:
Uses: no uses
Comments: Known from Lake Sorell, Lake Crescent and the Clyde River (Ref. 7300). Recoeded from associated streams on the Central Tasmanian Plateau (Ref. 44894). The Inland Fisheries Service (IFS) established two translocated populations in farm dams (surface areas <0.60 ha) in the Clyde River catchment, between 1996-1998. One population is in the Interlaken area near Lake Sorell and the other is in the Jericho areas south of Lake Crescent (Ref. 51290). Currently very abundant in Lake Crescent and reasonably abundant in Lake Sorell; the two translocated populations are presently abundant with the presence of several year classes indicating that the populations are self-sustaining and well established (Ref. 51290). Population is primarily threatened by recent drought and persistent low water levels in lakes Crescent and Sorell; competition and predation from introduced fish is also a significant threat (Ref. 51290). Status of threat: Endangered (Ref. 51305).

Length at first maturity / Size / Weight / Age

Maturity: L_m ?, range 8 - ? cm
Max length : 24.0 cm SL male/unsexed; (Ref. 44894); common length : 15.0 cm SL male/unsexed; (Ref. 5259)

Facultative air-breathing in the genus (Ref. 126274); Lives in rocky areas and vegetated margins of lakes and streams (Ref. 5259), primarily in lakes preferring still or gently flowing waters (Ref. 51290, 44894). Adults prefer the shelter provided by complex habitats such as rocky lake shores and also in-lake macrophytes beds and marsh habitats (Ref. 51290). Juveniles occur in the water column until 4-5 months of age (40 mm in length) and then move inshore seeking shelter and larger prey items (Ref. 51290). Shoaling in open water when young (Ref. 44894). Feeds on insects, insect larvae and crustaceans (Ref. 5259, 44894) and mollusks with cannibalism of eggs and juvenile fish being common (Ref. 51290, 44894). Breeds in early spring among rocks in the shallows (Ref. 44894). Most fish live for 3-4 years with some reaching over 6 years of age (Ref. 51290).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00490 (0.00205 - 0.01170), b=3.12 (2.91 - 3.33), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.44 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (tm=1-2).

Fishing Vulnerability (Ref. 59153): Low vulnerability (19 of 100).
