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=0.00813 (0.00364 - 0.01815), b=3.08 (2.88 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245). |
|
Trophic level (Ref. 69278) |
3.5 ±0.4 se; based on size and trophs of closest relatives |
| Generation time | 7.8 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies. |
|
Resilience (Ref. 120179) |
Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100). |
|
Fishing Vulnerability (Ref. 59153) |
High vulnerability (56 of 100). 🛈 |
