Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 9 - 12; Anal soft rays: 20 - 26. Distinguished from all other members of the genus by the combination of the following characters: 20-26 anal rays; 9-12 dorsal rays; 31-32 scales in lateral row; body depth 25-31% SL; and color pattern of male in life with greyish brown head and body with diffuse dark brown blotches irregularly dispersed on body and always with a row of 5-9 larger blotches more or less irregularly organized above axial stripe (Ref. 26687).

Non-annual breeder. Is very difficult to maintain in aquarium (Ref. 27139).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

Egg clusters are carried by females under the ventral fin (Ref. 26687).

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=0.00479 (0.00190 - 0.01207), b=3.13 (2.91 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Assuming fec < 100, egg cluster of 13-15 eggs).

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

Price category (Ref. 80766): Unknown.

Oryzias marmoratus (Aurich, 1935)
