Estimates based on models
|
Phylogenetic diversity index (Ref. 82804) |
PD50 = 0.6426 [Uniqueness, from 0.5 = low to 2.0 = high]. |
| Bayesian length-weight | a=0.00229 (0.00092 - 0.00573), b=3.19 (2.98 - 3.40), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245). |
|
Trophic level (Ref. 69278) |
4.5 ±0.71 se; based on food items. |
|
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). 🛈 |
