Actinopteri (ray-finned fishes) > Gadiformes
(Cods) > Merlucciidae
Etymology: Merluccius: Latin, mar, maris = the sea + Latin, lucius = pike (Ref. 45335); tasmanicus: Named after its type locality, Tasman Bay (Ref. 57718)
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range - 91 m (Ref. 57718), usually - m (Ref. ). Deep-water; 0°C -
Western Pacific: Japan and New Zealand. Southeast Pacific and Southwest Atlantic: Patagonian, Chilean and Argentine waters. Based on the geographical distance between the populations and some morphometric and meristic differences observed, assigning a subspecific name to each of these populations seems appropriate.

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 4.1 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate vulnerability (42 of 100) .
