Percentage survival after 14 days was 67.9 ± 1.0% (1 000/L), 50.2±0.6% (3 000/L) and 29.3 % (5 000/L). Figure 1 Percentage survival of Thermocyclopsp. with time at different temperatures Figure 2 Percentage survival of Thermocyclopsp. with time at different storage densities 1.2 Fatty acid composition Generally, the fatty acid (FA) composition was dominated by saturated fatty acids (SFAs) followed by monounsaturated fatty acids (MUFAs) while Polyunsaturated fatty acids (PUFAs) were the least dominant (Table 1). At 4 °C, SFAs increased from the 7th day (59.00%) to the 14th day (65.66%), while a decrease in MUFAs was observed from the 7th (32.99%) to the 14th day (25.8%) of the experiment. At 12 °C, total SFAs were highest on the 14th day (61.08%) compared to MUFAs and PUFAs at 33.31 ± 6.71% and 5.61 ± 1.62% respectively (Table 1). Amongst the SFAs at 4 °C, Palmitic acid (C16:0) and Stearic acid (18:0) were dominating. The highest
