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=0.00562 (0.00298 - 0.01063), b=3.13 (2.97 - 3.29), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245). |
|
Trophic level (Ref. 69278) |
4.1 ±0.7 se; based on size and trophs of closest relatives |
|
Resilience (Ref. 120179) |
Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.). |
|
Fishing Vulnerability (Ref. 59153) |
High to very high vulnerability (74 of 100). 🛈 |
