Abstract
    In crustaceans, assimilation of nutrients depends on their complex digestive systems. Early studies were limited to morphology and histology. More recently, biochemistry and molecular biology studies have generated interesting results about the processes of digestion and food utilization. Selection of foods in nature; consumption in aquaculture; ingestion; transit of nutrients in the digestive tract; mechanical digestion; enzyme activity and their physiological variations and control of their synthesis, use of compound diets, cellular absorption and storage as well as transfer of excreta are the main functions of the digestive tract of crustaceans. Numerous studies have addressed these subjects in relation to several crustacean species living in European waters, including Homarus, crayfish Astacus, shrimps Crangon, Palaemonetes and Paiaemon, crabs Cancer and Portunus, as well as other genera, such as Penaeus and Macrobrachium living in overseas territories. This article reviews the results of these studies, mainly developed by French teams during recent years and identifies new research topics.
