Abstract:Ammonia excretion of the Utah strain of Artemia sp. grown in axenic culture media was followed throughout the different stages of larval development. The ammonia accumulated in the culture medium does not affect ammonia excretion rates under our laboratory conditions. Growth rate, density and starvation all affect ammonia excretion. Ammonia excretion is directly related to the numerical growth index and inversely related to Artemia sp. density. Starved adult Artemia sp. excrete considerably lower amounts of ammonia than brine shrimp grown in nutritive medium. In view of the difficulties often encountered in estimating the excretion rates of small crustaceans, our culture conditions would appear advantageous for further studies on the purine metabolism of Artemia sp.
