Abstract Lepidocephalus thermalis, the Indian Spiny Loach is a comestible fresh water fish with ethnic flavor and taste found pervasive in Tamil Nadu. In this study, antibacterial activity of whole aqueous as well as boiled fish extract, hydrolyzed fish protein extract, lipid chloroform extract and aqueous fish mucus extract against human, fish pathogens were studied. The FTIR and NMR analysis of the lipid extracts revealed the presence of EPA and DHA. The lipid extracts showed maximum antimicrobial activity against Pseudomonas aeruginosa, Staphylococcus aureus, Staphylococcus epidermidis, Salmonella typhii and Proteus vulgaris at even low concentration of 15 μg/ml. Therefore, this study demonstrates the nutraceutical potential of this fish which will be helpful for aqua culturists for bioprospecting the intuitive species for human consumption.
