Estimates based on models
|
Phylogenetic diversity index (Ref. 82804) |
PD50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high]. |
| Bayesian length-weight | a=0.00309 (0.00144 - 0.00663), b=3.24 (3.07 - 3.41), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245). |
|
Trophic level (Ref. 69278) |
4.0 ±0.6 se; based on size and trophs of closest relatives |
|
Resilience (Ref. 120179) |
Low, minimum population doubling time 4.5 - 14 years (Preliminary low fecundity). |
|
Fishing Vulnerability (Ref. 59153) |
Moderate vulnerability (37 of 100). 🛈 |
