Body weight gain, Feed Conversion Ratio (FCR) and daily feed intake. A Evolution of body weight gain of rainbow trout fed with different experimental diets from the first feeding and during 12 weeks. Mean body weights for each diet are presented as mean ± standard error. B Feed Conversion Ratio (FCR) were calculated per tank as follows: FCR = feed intake (g)/ fish weight gain (g) during the 12 weeks. C Daily feed intake was calculated for each tank as follows: feed consumed (g) / mean kg body weight.day. Mean values for each diet are presented as mean ± standard error. T0: commercial fishmeal-rich diet (n = 1); Tv: full terrestrial plant-based diet devoid of fishmeal (n = 2); F1: plant-based diet in which 11% of plant proteins have been replaced by 5.5% of proteins from yeast (YEA) and 5.5% of proteins from insect larvae (INS) (n = 2); F2: plant-based diet in which 16.5% of plant proteins have been replaced by 5.5% YEA, 5.5% INS and 5.5% processed animal proteins (PAP) (n = 2)
