Estimates based on models
|
Phylogenetic diversity index (Ref. 82804) |
PD50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high]. |
| Bayesian length-weight | a=0.00093 (0.00041 - 0.00212), b=2.99 (2.79 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245). |
|
Trophic level (Ref. 69278) |
3.7 ±0.6 se; based on size and trophs of closest relatives |
|
Resilience (Ref. 120179) |
High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.). |
|
Fishing Vulnerability (Ref. 59153) |
Moderate vulnerability (40 of 100). 🛈 |
