Estimates based on models
|
Phylogenetic diversity index (Ref. 82804) |
PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high]. |
| Bayesian length-weight | a=0.00589 (0.00252 - 0.01376), b=3.07 (2.87 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245). |
|
Trophic level (Ref. 69278) |
3.3 ±0.4 se; based on size and trophs of closest relatives |
|
Resilience (Ref. 120179) |
High, minimum population doubling time less than 15 months (tmax=3). |
|
Fishing Vulnerability (Ref. 59153) |
Low vulnerability (14 of 100). 🛈 |
