Abstract

A very common practice in studies on fish feeding is to determine the diet of the species by an analysis of stomach contents. It is undertaken by the methods of numerical, volumetric, gravimetric and occurrence frequencies. Since their utilization is not always possible, an alternative method based on attribution of points is suggested. It consists of evaluating food items starting from total food weight and simple visual inspection of stomach contents
