Teleostei (teleosts) > Beloniformes (Needle fishes) > Adrianichthyidae (Ricefishes) > Oryziinae
Etymology: Oryzias: Greek, oryza = rice; because of the habitat used by this fish (Ref. 45335).

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 (0.00189 - 0.01213), 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): 3.0 ±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).

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