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=0.01514 (0.00759 - 0.03019), b=3.05 (2.87 - 3.23), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245). |
|
Trophic level (Ref. 69278) |
3.8 ±0.1 se; based on diet studies. |
|
Resilience (Ref. 120179) |
Low, minimum population doubling time 4.5 - 14 years (tmax=12). |
|
Fishing Vulnerability (Ref. 59153) |
Moderate to high vulnerability (46 of 100). 🛈 |
