Abstract

Abstract: In recent years, the marine medaka ( Oryzias melastigma ), also known as the Indian medaka or brackish medaka, has been recognized as a model fish species for ecotoxicology and environmental research in the Asian region. O. melastigma has several promising features for research, which include a short generation period (3–4 months), daily spawning, small size (3–4 cm), transparent embryos, sexual dimorphism, and ease of mass culture in the laboratory. There have been extensive transcriptome and genome studies on the marine medaka in the past decade. Such omics data can be useful in understanding the signal transduction pathways of small teleosts in response to environmental stressors. An omics-integrated approach in the study of the marine medaka is important for strengthening its role as a small fish model for marine environmental studies. In this review, we present current omics information about the marine medaka and discuss its potential applications in the study of various molecular pathways that can be targets of marine environmental stressors, such as chemical pollutants. We believe that this review will encourage the use of this small fish as a model species in marine environmental research. Highlights: Oryzias melastigma is a model fish species for ecotoxicology and environmental research. Extensive transcriptome and genome studies are available on the marine medaka. Omics data is useful in understanding the signal transduction pathways upon environmental stressors.
