Javanese rice fish
The Oryzias genus consists of rice fish, which are globally recognized and valued for their use as experimental model organisms in various biochemical studies. These fish are commonly found in mangrove and estuarine habitats in Southeast Asia. Among the 34 species within this genus, Oryzias javanicus has been reported for the first time in the Andaman Nicobar group of islands and the Indian island ecosystem.
During a faunal survey aimed at documenting the aquatic fauna diversity of Great Nicobar Island, the species was discovered in an estuarine creek. This finding marks the first recorded occurrence of Oryzias javanicus in this region. The study documented important information such as morphological data, live coloration, and details about the fish's natural habitat.
This new record of Oryzias javanicus expands our knowledge of the diversity of Oryzias species in the Indian region. The presence of this species in the Andaman Nicobar islands and the Indian island ecosystem provides a valuable addition to the understanding of the distribution and ecology of rice fish in this area.
Overall, the discovery of Oryzias javanicus in the mentioned locations contributes to the ongoing exploration of the biodiversity in the region and emphasizes the importance of studying and documenting the various species within the Oryzias genus.
