EFFECT OF NA/MG RATIO IN ARTIFICIAL AND NATURAL SEAWATER ON THE HATCHABILITY OF ARTEMIA CYSTS
The experiment was conducted to evaluate the effect of Na+/Mg2+ratio in hatching medium on the hatchability of Artemia cysts, by using artificial seawater formulated at different concentration of Na+, Mg2+ and different Na/Mg ratio and natural seawater adjusted at different Na/Mg ratio. The results showed Na+and Mg2+was the limited factor for Artemia cysts hatching, and the optimum Na/Mg ratio ranged from 6 to 8. It was concluded that the content of Na+, Mg+ and the ratio of Na/Mg in the brine are the key factors to affect hatching and growth of Artemia also indicated the ions and trace element in natural seawater could reduce the effect of Artemia cysts.
