A series of substrate based aquaculture systems have been developed to reduce the cost of finfish and shellfish farming. Periphyton acts as important food component for finfish and shellfishes. The present study is aimed to assess the growth and survival of fish (Labeo fimbriatus, Barbodes carnaticus) and shell fish (Macrobrachium rosenbergii) in a substrate based system for a period of 6 months. Sugarcane bagasse is used as a substrate for the growth of periphytons. The experiment was carried out in three treatments, T1 (only substrate), T2 (substrate + feed) and T0 (only feed/ control) with triplicates. The results of the study showed maximum average weight in T2 ( L. fimbriatus 141.17
