Description The study of the feeding habits of fish and other animals based upon analysis of
stomach content has become a standard practice (Hyslop 1980). Stomach content analysis
provides important insight into fish feeding patterns and quantitative assessment of food
habits is an important aspect of fisheries management. Lagler (1949) pointed out that the
gut contents only indicate what the fish would feed on. Accurate description of fish diets
and feeding habits also provides the basis for understanding trophic interactions in aquatic
food webs. Diets of fishes represent an integration of many important ecological
components that included behavior, condition, habitat use, energy intake and inter/intra
specific interactions. A food habit study might be conducted to determine the most
frequently consumed prey or to determine the relative importance of different food types to
fish nutrition and to quantify the consumption rate of individual prey types. Each of these
questions requires information on fish diets and necessitates different approaches in how
one collects and analyzes data. Here, we outline qualitative and quantitative techniques
used to describe food habits and feeding patterns of fishes.
