Bayesian length-weight
|
a=0.00794 (0.00391 - 0.01613), b=3.12 (2.94 - 3.30), 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 |
|
Generation time |
4.8 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies. |
Resilience (Ref. 120179) |
Low, minimum population doubling time 4.5 - 14 years (tm=5; tmax=12; K=0.23). |
