Teleostei (teleosts) > Beloniformes (Needle fishes) > Adrianichthyidae (Ricefishes) > Oryziinae
Etymology: Oryzias: Greek, oryza = rice; because of the habitat used by this fish (Ref. 45335).
Eponymy: Dr Sam Bomansha Setna FMRS (1895–1969) was a marine biologist at the Royal Institute of Science and Department of Industries, Bombay. [...] (Ref. 128868), visit book page.

Found in estuaries, but can live temporarily in freshwater. Inhabits quiet rocks and corners of creeks and backwaters. Can withstand a wide range of salinity varying from 4.36 to 1.35% (Ref. 48443). Breeds easily throughout the year peak period during July and August. Larvicidal fish and eats mosquito larvae at the early instar stages. A suitable fish in malaria infected areas (Ref. 48443).

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

Barbed sperm bundles or spermatophores are passed from male to female. Fertilized eggs are then laid one-by-one or en masse over a relatively large area rather than in one location (Ref. 80012).

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): 2.4 ±0.22 se; based on food items.

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