HPLC screening of medicinal plant extracts and medicated fish feed for Carrasius auratus (Linn)

Abstract

Aqueous extracts of selected medicinal plants such as Leucas aspera, Achyranthes splendens, and Swertia chirayita were prepared and screened for its protein content by High Performance Liquid Chromatography. With this background the present study aims at increasing the survival rate of ornamental fish. The self-formulated fish feed made from the extracts of Leucas aspera, Achyranthes splendens, and Swertia chirayita leaves and fishery wastes. The medicinal feed surpassed the quality of commercial fish feed by having higher protein and fibre along with medicinal properties. This enabled the fish to combat commonly found fish pathogens in water thereby increasing the survival rate.
