Estimates based on models

Phylogenetic diversity index (Fonte Biblio. 82804): PD₅₀ = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Fonte Biblio. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

Resilienza (Fonte Biblio. 120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100). 🛈

Opsaridium ubangiense (Pellegrin, 1901)
