Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00977 (0.00566 - 0.01687), b=3.16 (3.02 - 3.30), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 2.6 ±0.5 se; based on size and trophs of closest relatives

लौटाव (Ref. 120179): माध्यम, न्यूनतम जनसंख्या दुगनी होने का समय 1.4 - 4.4 वर्ष। (Fec=190).
