鳟鱼饮食中的碳水化合物掺入会在消化和代谢水平上产生问题。碳水化合物的消化利用很大程度上取决于它们的分子量。此外，对于复合碳水化合物（淀粉），不同的因素（例如淀粉的掺入水平、消耗量和物理状态）会影响消化率。消化率的测量本身就面临着方法学上的困难。粪便的收集方式会影响消化系数。膳食碳水化合物实际上是能量的来源。然而，饮食中超过一定水平时，可能会出现不耐受现象。现在出现的问题是确定碳水化合物在给定饮食中可吸收的代谢能量的最佳部分。
Carbohydrate incorporation in trout diets arises problems both at digestive and metabolic levels. Digestive utilization of carbohydrate closely depends on their molecular weight. In addition, in the case of complex carbohydrates (starches), different factors such as the level of incorporation, the amount consumed and the physical state of starch influence the digestibility. The measurement of digestibility in itself is confronted with methodological difficulties. The way the feces are collected can affect the digestion coefficient. Dietary carbohydrates actually serve as a source of energy. Nevertheless, above a certain level in the diet, intolerance phenomena may appear. The question that arises now is to establish the optimal part that carbohydrates can take in the metabolizable energy of a given diet.
