Studies on the culture of artemia using ricebran supplemented with marine yeast (DEBARYOMYCES FORMICARIUS)

The brine shrimp Artemia is playing an important role in aquaculture. The global requirements of Artemia biomass and cyst as important sources of live food for a wide variety of shrimps and fishes increased with the development of intensive aquaculture technology. The demand for large quantities of high quality Artemia biomass and cyst is increasing exponentially. A huge volume of coconut water is wasted by the local farmers which is a good organic source for the culture of marine yeasts. In the present study coconut water is used as the culture medium for the yeast growth. D. formicarius was cultured by the coconut water. After 48 hours yeasts were harvested and mixed with rice bran, then fed to Artemia at different concentrations. The Yeasts cultured in coconut water medium supported maximum growth, survival and reproduction of Artemia. The effect of marine yeast (D.formicarius,) cultured in coconut water on the growth, survival and reproductive performance of A.parthenogenetica are undertaken in order to formulate a good quality feed for Artemia.
