Values are means ± s.d. Two-way analysis of variance was carried out in order to assess effects of diet and cycle of reproduction. Replicates to asses statistical effect on reproductive performances of females and egg quality correspond to different individual females (n = 90 females per treatment). Replicates to asses statistical effect on fingerling biometric parameters correspond to different individual egg batches (n = 10 egg batches per treatment). “n.s”: not significant; “*”: P < 0.05; “**”: P < 0.01; “***”: P < 0.001
