Estimates based on models
|
Phylogenetic diversity index (Ref. 82804) |
PD50 = 0.5007 [Uniqueness, from 0.5 = low to 2.0 = high]. |
| Bayesian length-weight | a=0.01096 (0.00509 - 0.02362), b=3.03 (2.84 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245). |
|
Trophic level (Ref. 69278) |
3.9 ±0.4 se; based on size and trophs of closest relatives |
| Generation time | 5.6 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies. |
|
Resilience (Ref. 120179) |
Medium, minimum population doubling time 1.4 - 4.4 years (K=0.20; tmax=9). |
|
Fishing Vulnerability (Ref. 59153) |
Low to moderate vulnerability (32 of 100). 🛈 |
