Estimates based on models

Preferred temperature (Ref. 123201): 5.7 - 20.7, mean 15.6 °C (based on 39 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00032 (0.00020 - 0.00051), b=3.24 (3.11 - 3.37), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.1 ±0.7 se; based on size and trophs of closest relatives

लौटाव (Ref. 120179): निम्न, न्यूनतम जनसंख्या दुगनी होने का समय 4.5 - 14 वर्ष। (Preliminary K or Fecundity.).
