Estimates based on models
|
Phylogenetic diversity index (Ref. 82804) |
PD50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high]. |
| Bayesian length-weight | a=0.00912 (0.00412 - 0.02018), b=3.04 (2.85 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245). |

Trophic level (Ref. 69278) |
3.5 ±0.37 se; based on food items. |
|
Resilience (Ref. 120179) |
Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tmax>3). |
|
Fishing Vulnerability (Ref. 59153) |
Low to moderate vulnerability (34 of 100). 🛈 |
