a=0.00813 (0.00364 - 0.01815), b=3.08 (2.88 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245). |
Trophic level (Ref. 69278) |
3.5 ±0.4 se; based on size and trophs of closest relatives |
Resilience (Ref. 120179) |
Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100). |
Fishing Vulnerability (Ref. 59153) |
