The impacts of grazing by tilapias (Oreochromis niloticus L.) on periphyton communities growing on artificial substrate in cages

Abstract

This study describes the development of periphytic communities established on artificial substrates in tilapia (Oreochromis niloticus) cages during a 10-week experiment conducted in the Meghna River, Bangladesh. Qualitative and quantitative characteristics of the periphyton were recorded, including diatom community composition and primary productivity. Fish grazed actively on the periphyton and there was a rapid fall in periphyton biomass following their introduction to the cages. Grazing significantly (P
