Southwest Pacific: endemic to New Zealand.

Length at first maturity / Size / Peso / Age

Maturity: L_m ?, range 80 - ? cm
Max length : 185 cm TL maschio/sesso non determinato; (Ref. 44724); 156.0 cm TL (female); common length : 60.0 cm TL maschio/sesso non determinato; (Ref. 9258); common length :100 cm TL (female); peso massimo pubblicato: 25.0 kg (Ref. 11115)

Commonly found in lakes and rivers (Ref. 9258). Inhabits stony rivers (Ref. 9072). Migrates to the sea to breed. Oviparous (Ref. 205). Marketed fresh, smoked and frozen; eaten fried and broiled (Ref. 9988). Reports of reaching up to 2 meters and 50 kilograms are rare and more common historically; in recent times, only a few exceed 120 cm TL (Ref. 82796).

Estimates based on models

Preferred temperature (Ref. 123201): 10.6 - 18.3, mean 15.1 °C (based on 138 cells).

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

Bayesian length-weight: a=0.00093 (0.00076 - 0.00115), b=3.20 (3.15 - 3.25), in cm total length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 4.5 ±0.5 se; based on diet studies.

Resilienza (Ref. 120179): Molto basso, tempo minimo di raddoppiamento della popolazione più di 14 anni (Tmax=60; tm=10-48 years based on age-length relationship.).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).

Price category (Ref. 80766): Unknown.
