Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00559 - 0.01790), b=3.06 (2.90 - 3.22), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 2.7 ±0.39 se; based on food items.

लौटाव (Ref. 120179): माध्यम, न्यूनतम जनसंख्या दुगनी होने का समय 1.4 - 4.4 वर्ष। (Preliminary K or Fecundity.).

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

Price category (Ref. 80766): Unknown.
