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=0.01514 (0.00534 - 0.04293), b=2.93 (2.68 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245). |
|
Trophic level (Ref. 69278) |
3.3 ±0.5 se; based on size and trophs of closest relatives |
|
Resilience (Ref. 120179) |
Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.). |
|
Fishing Vulnerability (Ref. 59153) |
Low to moderate vulnerability (35 of 100). 🛈 |
