Estimates based on models

Preferred temperature (Ref. 115969): 11.3 - 21.8, mean 19.5 (based on 65 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00407 (0.00265 - 0.00627), b=3.02 (2.89 - 3.15), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.55 se; based on food items.

लौटाव (Ref. 120179): निम्न, न्यूनतम जनसंख्या दुगनी होने का समय 4.5 - 14 वर्ष। (Assuming fecundity<100).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).
