Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00813 (0.00366 - 0.01807), b=3.08 (2.88 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.6 ±0.4 se; based on size and trophs of closest relatives
लौटाव (Ref.
120179): निम्न, न्यूनतम जनसंख्या दुगनी होने का समय 4.5 - 14 वर्ष। (Assuming fecundity<100).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (48 of 100).
Nutrients (Ref.
