OES Theses and Dissertations

The effects of elevated CaCl2 , MgCl2 , combination CaCl2 and MgCl2 concentrations and their associated ionic strengths on larval growth and survival of the freshwater prawn, Macrobrachium rosenbergii were investigated in the laboratory. Larvae were reared in diluted seawater of 15 parts per thousand salinity with elevated calcium concentrations of 330 parts per million and elevated magnesium concentrations of 1275 parts per million. Control larvae were also reared with elevated NaCl concentrations to duplicate the ionic strength increases of the combination CaCl2 - MgCl2 test solution which had the highest ionic strength. A …
