Abstract (EN): The post-prandial glycemic response of juvenile European sea bass (initial mean weight 10 g) was determined following acclimation to experimental diets that contained a pea seed meal included at two levels. The ingredient provided a source of starch that replaced purified corn starch/yellow dextrin (2:1) in a reference diet based on fishmeal as the main protein component. The total carbohydrate levels amounted to 25% of the dry matter content and contributed (18%) to the overall gross dietary energy value of 20 MJ/kg. After a 12-wk feeding trial, in which the sea bass grew to over 40 g (mean weight), the plasma glucose profile was recorded over a 24-h period (0 h, 1 It, 3 h, 6 h, 9 h, 12 h, and 24 h) following a meal fed to satiation. Results showed that sea bass are able to regulate their glucostatic tolerance to dietary starch, and that the pea seed meal modulated this effect. Peak post-prandial responses varied between 1 to 9 h and were significantly delayed for the reference diet. Efficacy of glucose assimilation improved for the highest level of pea seed meal inclusion (40% by weight). The relevance of carbohydrate complexity with respect to feed formulation and nutritional requirements of sea bass are discussed.
