Estimates based on models

Preferred temperature (Ref. 123201): 7.4 - 15.6, mean 12.3 °C (based on 83 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6289 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00132 (0.00062 - 0.00280), b=3.11 (2.92 - 3.30), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 4.3 ±0.64 se; based on food items.

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

Fishing Vulnerability (Ref. 59153): Very high vulnerability (78 of 100).

Neoharriotta pinnata (Schnakenbeck, 1931)
