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=0.00490 (0.00325 - 0.00739), b=3.19 (3.06 - 3.32), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245). |
|
Trophic level (Ref. 69278) |
3.2 ±0.2 se; based on diet studies. |
| Generation time | 11.0 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies. |
|
Resilience (Ref. 120179) |
Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.). |
|
Fishing Vulnerability (Ref. 59153) |
High vulnerability (60 of 100). 🛈 |
