This paper presents a review of the knowledge on the chemical mecanisms of digestion, feeding rates and the digestibility of natural food by African freshwater fish species. Most of the studies deal with cichlid fishes. Among them, stomach acid secretion is tied to feeding and contributes to the breakdown of algal walls or macrophyte cells. Pepsin, trypsin and chymotripsin are the main proteases which have been studied ... By comparing enzyme activity and feeding behavior, amylase activity is noticeably greater in herbivores rather than in carnivores. Such differences are less pronounced for the proteases ...Feeding patterns and gut passage or gastric evacuation times have been investigated to estimate daily digestion
