AN IMPROVED ARTIFICIAL SEA WATER COMPOSITION FOR THE LARVAL REARING OF MACROBRACHIUM ROSENBERGII

摘要

Macrobrachium rosenbergii is considered a freshwater species, but at the larval stage of the animal depends on brackish water. Once the individual shrimp has grown beyond the planktonic stage and become a juvenile, it will live entirely in freshwater, In order to make it possible to culture Macrobrachium rosenbergii away from the coastal regions as the life cycle of the Macrobrachium rosenbergii at the larval stage requires brackish water whereas the latter stage Macrobrachium rosenbergii a freshwater species; is known to be a freshwater species; The present invention to provide an improved artificial sea water composition having suitable salinity to control mortality rate of the Macrobrachium rosenbergii and achieve higher survival rate of Macrobrachium rosenbergii. The brackish water composition is achieved by the mixture of the electrolytes dissolved in water. The electrolyte mixture which, being dissolved in a proper amount of water can form an aqueous solution which stimulates the natural sea water in composition
