Etymology: Hydrolagus: hydro-, combining form of hydor (Gr.), water; lagos (Gr.), hare, i.e., “water rabbit,” probably referring to three pairs of tooth plates, which tend to protrude from the mouth like a rabbit’s incisors. (See ETYFish); novaezealandiae: novus (L.), new, i.e., of New Zealand, in whose waters it occurs. (See ETYFish).

Estimates based on models

Preferred temperature (Ref. 115969): 8 - 13.7, mean 10.8 (based on 62 cells).

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

Bayesian length-weight: a=0.00240 (0.00122 - 0.00472), b=3.14 (2.96 - 3.32), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.46 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Assuming Fec <100).

Prior r = 0.28, 95% CL = 0.16 - 0.49, Based on 1 stock assessment.

Fishing Vulnerability (Ref. 59153): High vulnerability (58 of 100).

Climate Vulnerability (Ref. 125649): Very high vulnerability (76 of 100).

Preiskategorie (Ref. 80766): High.
