Description In Ichthyology, fish ecology & fisheries resource management, the information on diet & food
habits are valuable in the decision-making process related to natural resources (Kido, 1996). Fish
gut content analysis provides an important insight into feeding patterns & quantitative assessment
of feeding habits is an important aspect of fisheries management. Fish diet represents an integration
of many important ecological components that includes behaviour, condition, habitat use, energy
intake & inter & intra-specific interactions, etc. A valid description of fish diets & feeding habits also
provides the basis for understanding trophic interactions in aquatic food webs. Conceptually, trophic
relations of fishes begin with the food & feeding habits & gut content analysis can be used to
evaluate the habitat preferences, prey selection, effects of ontogeny & developing conservation
strategies (Chipps & Garvey 2007). A food habit study might be conducted to investigate the most
frequently consumed prey or to determine the relative importance of different food types to fish
nutrition & to quantify the ingestion rate of individual food types. All such questions demands
information on fish diets & requires different approaches in how one collects & analyzes data. In
summary, gut content analysis is used in the understanding of many aspects of fish ecology on
individual, population & ecosystem levels. It helps us to study & elucidate specific problems of
interactions, evolution, speciation, invasions & fishery management nature protection. As a result,
stomach content studies could be incorporated into a variety of different research objectives.
Consequently, the study of the gut content is not only way to know the diet but also superior
source of information on many aspects of fish biology & ecology.
