Estimates based on models
|
Phylogenetic diversity index (Ref. 82804) |
PD50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high]. |
| Bayesian length-weight | a=0.00741 (0.00439 - 0.01251), b=3.11 (2.96 - 3.26), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245). |
|
Trophic level (Ref. 69278) |
3.3 ±0.4 se; based on size and trophs of closest relatives |
| Generation time | 10.0 ( 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 (62 of 100). 🛈 |
