    A non-human species that has been widely studied in the laboratory for helping scientists understanding the biological processes is called a ‘model organism’. Their inherent characteristics include easy maintenance, anatomical and physiological similarities to humans, high reproductive rate and large offspring number, and a short generation time (the time period from birth to reproduction). Among the fishes, zebra fish (Danio rerio) is widely accepted globally as a model organism for research in freshwater providing valuable insights into cell, tissue, organ, and system level. However, for studies involving marine and brackish waters, it is not advisable to superimpose the cues obtained from freshwater model organism, which necessitates the use of a species with marked euryhaline characteristics. Oryzias dancena (Hamilton, 1822), with tolerance to varying salinities, are small and easy to bred, and are capable of being maintained in large numbers; therefore offers as an excellent alternate fish model organism for experiments in marine systems.
