Estimates based on models
|
Phylogenetic diversity index (Ref. 82804) |
PD50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high]. |
| Bayesian length-weight | a=0.00309 (0.00137 - 0.00696), b=3.18 (2.99 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245). |
|
Trophic level (Ref. 69278) |
3.7 ±0.4 se; based on size and trophs of closest relatives |
|
Resilience (Ref. 120179) |
Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.). |
|
Fishing Vulnerability (Ref. 59153) |
Very high vulnerability (83 of 100). 🛈 |
