Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805)
PD₅₀ = 0.5000 many relatives (e.g. carps) 0.5 - 2.0 few relatives (e.g. lungfishes)

Trophic Level (Ref. 69278)
3.3 ±0.4 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278)
High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.)

Vulnerability (Ref. 59153)
Low to moderate vulnerability (27 of 100)
