Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01585 (0.00617 - 0.04070), b=2.96 (2.74 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.1 ±0.1 se; based on size and trophs of closest relatives

Daya lenting (Ref. 120179): sedang, Waktu penggandaan populasi minimum 1.4 - 4.4 tahun (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (49 of 100).
