Abstract

The pattern of trophic organizations within fish community reflect the food resource partitioning existing in a given marine

ecosystem. The present investigation was undertaken to understand the shifts in the dietary pattern of three demersal finfish

species at two different sites, one where intense trawling is practised and the other where no trawling is undertaken. Multivariate

statistical analysis

viz

., cluster analysis was carried out to understand these patterns. Results of the study revealed interesting

diet sharing patterns among the selected demersal fishes at trawled and non-trawled sites.
