Life cycle and mating behavior 成熟 | 繁殖 | 放精 | | 生産力 | 幼生

The female holds 2-4 eggs between her pelvic fins, where the male fertilizes them for about 30 seconds. Only then the female swims to a suitable spot, where she attaches the very sticky eggs. The pair repeats this process until about 100 eggs have been fertilized and attached (Ref. 1672).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02239 (0.00916 - 0.05471), b=3.03 (2.84 - 3.22), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
栄養段階 (Ref. 69278):  3.0   ±0.3 se; based on size and trophs of closest relatives
回復力 (Ref. 120179):  高い, 15か月以下の倍増期間の最小個体群 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
