摘要

Diet compositions expressed in weight are essential to determine the trophic relationships in energetic terms between the compartments within a system. Data from stomachs were compiled from a number of sources (62102 stomachs), covering four broad areas such as the Northwest Atlantic, South Africa, Senegal and the Azores Islands in order to explore the empirical relationships between the frequency of occurrence, which is of limited use in a modelling context, and the preferred index, relative weight composition. These empirical relationships were found to be highly significant.
