Effect of maternal nutrition on fry performances (A) during classic growth trial where fry were fed a CO diet for 12 weeks (evolution of mean body weight (g) during the 12 week-trial, individual weight (g) and survival percent (%) after 8 and 12 weeks) and (B) after 4 weeks of nutritional challenge where fry were fed the MAO diet (individual weight (g) and survival percent (%)). One-way analysis of variance was carried out in order to assess effects of maternal nutritional origin on individual final weight; replicates correspond to different individual fingerlings (n = 30 fingerlings per treatment). Kruskal-Wallis test was carried out to assess the effect of maternal nutritional origin on survival rate (n = 4 racks at week 8 and n = 2 racks at week 12) and the weight mean during rearing (n = 2 racks per treatment from week 0 to week 4 and n = 4 racks from week 5 to week 8). “n.s”: not significant; “*”: P < 0.05
