Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

In captivity, as the sperm are released the female sinks to the bottoms, resting on one of her pectoral fins while she starts fanning with the other pectoral fin. At this time, some eggs are released which fall into the pelvic fin basket and are apparently fertilized at that time.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01660 (0.00906 - 0.03038), b=2.96 (2.80 - 3.12), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 2.9 ±0.3 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).

Scleromystax barbatus (Quoy & Gaimard, 1824)
