Bayesian length-weight
|
a=0.01000 (0.00374 - 0.02675), b=2.97 (2.75 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245). |
Trophic level (Ref. 69278) |
3.6 ±0.6 se; based on size and trophs of closest relatives |
Resilience (Ref. 120179) |
High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.). |
Fishing Vulnerability (Ref. 59153) |
Low vulnerability (10 of 100). 🛈 |
