> Beloniformes (Needle fishes) > Adrianichthyidae (Ricefishes) > Oryziinae
Etymology: Oryzias: Greek, oryza = rice; because of the habitat used by this fish (Ref. 45335); orthognathus: Greek, orthos = right + Greek, gnathos = jaws (Ref. 45335).

Short description Chiavi di identificazione | Morfologia | Morfometria

Raggi dorsali molli (totale) : 8 - 11; Raggi anali molli: 23 - 25. Distinguished from all other species of the genus by its upturned mouth. Differs further by having 45-54 scales in lateral row, 8-11 dorsal rays and 23-25 anal rays (Ref. 26747).

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

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): 3.5 ±0.5 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Assuming fec < 100).

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

Price category (Ref. 80766): Unknown.
