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=0.00977 (0.00473 - 0.02021), b=3.08 (2.89 - 3.27), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245). |
|
Trophic level (Ref. 69278) |
3.6 ±0.6 se; based on size and trophs of closest relatives |
|
Resilience (Ref. 120179) |
Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100). |
|
Fishing Vulnerability (Ref. 59153) |
Moderate to high vulnerability (53 of 100). 🛈 |
