Yasodha Thirumal and Suresh Laavu

High Performance Liquid Chromatography technique based screening of medicinal proteins as fish feed were prepared from the selected medicinal plants such as Leucas aspera, Achyranthes splendens, and Swertia chirayita. The present study aims at arrival of quality profile of protein in the medicinal plants which are main ingredients in the fish feed. Antibacterial activity of the medicinal plant extracts was assessed and based on that the self-formulated fish feed was formulated. The medicinal feed surpassed the quality of commercial fish feed by having higher protein and fibre along with medicinal properties. In the present study fish pathogens were isolated from the infected fishes and cultured on a suitable medium. Control of pathogens by 80%, 92%and 87% Leucas aspera, Achyranthes splendens and Swertia chirayita respectively revealed the efficiency of medicinal plants than the control. This study enabled that the medicated fish feed curtails the high cost of fish diet and can be used as potential high quality alternative source in the aquaculture industry
