The Journal of the National Science Foundation of Sri Lanka publishes the results of research in all aspects of Science and Technology. The journal also has a website at http://www.nsf.gov.lk/. 2020 Impact Factor: 0.515The JNSF provides immediate open access to its content on the principle that making research freely available to the public supports a greater global exchange of knowledge.

Highlights

  • Freshwater prawns of the genus Macrobrachium Bate, 18681 are important macro invertebrates in freshwater and estuarine systems throughout the tropical and warm temperature areas of the world

  • Some previous studies 9-12 have produced important clarifications for Australian Macrobrachium species based on 16S mitochondrial gene region

  • This study was based on mitochondrial 16S rRNA gene region of seven Macrobrachium species collected from different geographical regions

Summary

Introduction

Freshwater prawns of the genus Macrobrachium Bate, 18681 are important macro invertebrates in freshwater and estuarine systems throughout the tropical and warm temperature areas of the world. Most species are widely distributed and require specific saline concentrations to complete larval development (euryhaline species) and others are land locked species This genus is one of the most challenging decapod crustacean groups. Two researchers[14,15] carried out phylogenetic studies using multiple gene regions. For these studies data were collected from a wide geographical range mainly from the south and south-eastern Asian regions. The above studies produced interesting information and insight regarding Macrobrachium taxonomy
