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)
3.7 ±0.3 se; Based on diet studies.

Resilience (Ref. 69278)
Very Low, minimum population doubling time more than 14 years (tm=6; tmax=60; also Musick et al. 2000 (Ref. 36717))

Vulnerability (Ref. 59153)
High vulnerability (65 of 100)
