Survival rate (%) of tilapia fish cultured in four different treatments. Fecundity analysis: The highest fecundity was found in treatment‐3 (2212 ± 14) fed with Chlorella vulgaris and the lowest fecundity was found in treatment‐4 (968 ± 176) fed with mixed phytoplankton. There were significant differences among all treatments (Fig. 6). Duponchelle et al. (28) observed fecundity of O. niloticus ranged from 149 to 2797, for fish weighing between 36 and 975 g in 1995; and from 178 to 1898, for fish weighing between 78 and 501 g in 1996. These findings confirm that fecundity in O. niloticus is variable. Fatty acid profiling: The fatty acid content of fish indicates that fish are superior in terms of the nutritional value. The saturated fatty acid (SFA) composition of Nile tilapia (O. niloticus) is presented in Table 2. Data referring to the fatty acid composition of the different diets showed the proportion of total saturated fatty acids (SFA) was higher in
