Culture of the brine shrimp, Artemia salina L., utilizing Dunaliella tertiolecta grown in swine waste-seawater mixtures and in defined inorganic medium Tiro, Leonardo B.
A comparative study was conducted on the growth of Dunaliella tertiolecta using defined inorganic medium and swine waste-seawater medium as sources of nutrients. The nitrogen concentration was maintained at ca 1200 ± 5° ug~at N 1⁻¹ for both media. There were no significant differences in the daily measurements of cell densities and dry weights of D. tertiolecta grown in defined inorganic medium and swine waste-seawater medium in either hatch or continuous culture systems. The algal biomass produced from continuous culture system was used as food for the brine shrimp, Artemia salina L. The brine shrimp fed with D. tertiolecta grown in swine waste-seawater medium and those fed with _D. tertiolecta cultured in defined inorganic medium showed no significant differences in their daily total length and percentage survival measurements. A 57-58% Artemia biomass conversion efficiency was calculated. Statistical analysis for biomass conversion efficiency showed no significant differences for Artemia fed with D. tertiolecta grown in swine waste-seawater medium and that fed with D. tertiolecta cultured in defined inorganic medium.
