Southwest Pacific: endemic to New Zealand.

Biology     Glossary (e.g. epibenthic)

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 of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00090 (-0.04653 - 0.04834), b=3.21 (3.18 - 3.24), based on LWR estimates for this species (Ref. 93245).
Trophic Level (Ref. 69278):  4.5   ±0.8 se; Based on diet studies.
Resilience (Ref. 69278):  Very Low, minimum population doubling time more than 14 years (Tmax=60; tm=10-48 years based on age-length relationship.).
Vulnerability (Ref. 59153):  Very high vulnerability (89 of 100) .
Price category (Ref. 80766):   Unknown.
