Actinopteri (ray-finned fishes) > Anguilliformes
(Eels and morays) > Anguillidae
Etymology: Anguilla: Latin, anguilla, .-ae = eel (Ref. 45335). More on author: Gray.
Environment: milieu / climate zone / depth range / distribution range
Marine; freshwater; brackish; demersal; catadromous (Ref. 51243). Subtropical; 34°S - 47°S
Southwest Pacific: endemic to New Zealand.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 80 - ? cm
Max length : 185 cm TL male/unsexed; (Ref. 44724); 156.0 cm TL (female); common length : 60.0 cm TL male/unsexed; (Ref. 9258); common length :100 cm TL (female); max. published weight: 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. 115969
): 10.6 - 18.3, mean 15.1 °C (based on 138 cells).
Phylogenetic diversity index (Ref. 82805
= 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.
Resilience (Ref. 120179
): 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) .
