Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00871 (0.00371 - 0.02044), b=3.07 (2.87 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
ຊັ້ນເຂດຮ້ອນ (Ref. 69278):  3.2   ±0.4 se; based on size and trophs of closest relatives
Generation time: 3.8 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
ຄວາມຢືດຢຸ່ນ (Ref. 120179):  ຕຳ່, ປະຊາກອນຕຳ່ສຸດທີ່ໃຊ້ເວລາສອງເທົ່າ 4.5 - 14 ປີ (K=0.29; tm=5-6).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (37 of 100).
