= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00794 (0.00655 - 0.00963), b=3.04 (2.98 - 3.10), in cm Total Length, based on LWR estimates for this species (Ref. 93245
Trophic Level (Ref. 69278
): 3.6 ±0.5 se; Based on size and trophs of closest relatives
Generation time: 2.7 ( na - na) years. Estimated as median LN(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): Very Low, minimum population doubling time more than 14 years (Fec=5).
Vulnerability (Ref. 59153
