Estimates based on models
|
Phylogenetic diversity index (Ref. 82804) |
PD50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high]. |
| Bayesian length-weight | a=0.01096 (0.00451 - 0.02668), b=3.10 (2.89 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245). |
|
Trophic level (Ref. 69278) |
3.5 ±0.50 se; based on food items. |
|
Resilience (Ref. 120179) |
Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.). |
|
Fishing Vulnerability (Ref. 59153) |
Moderate to high vulnerability (45 of 100). 🛈 |
