Thoeye, C.; Van der Linden, A.; Bernaerts, F.; Blust, R.; Decleir, W. (1987). The effect of diurnal temperature cycles on survival of Artemia from different geographical origin. Artemia Research and its Applications 1: 233-239

The temperature in a natural Artemia habitat usually shows diurnal cyclic variations. It is important for inoculation and culturing purposes to know the survival under such conditions. The survival of four Artemia strains, Great Salt Lake and San Francisco Bay (USA), and Sfax and Mégrine (Tunisia) was studied over a period of 7 days, in different conditions of constant or diurnal fluctuating temperatures at two salinities. For the Great Salt Lake strain, the temperature fluctuation had no effect on the survival, as compared to constant temperature regimes (at 35 pro mille). For the other strains, temperature fluctuations had either no influence, or a beneficial influence on survival. In general, the tolerance of Artemia to high temperatures was higher under conditions of alternating temperatures than of constant ones.
