Spoilage Causing Fish Skin Bacterial Flora

Abstract

To check for the presence of skin-related bacteria that could lead to fish spoiling, fish samples are taken from Peshawar's Ghanta-ghar market. Blood agar medium, MacConkey agar, Pseudomonas medium, nutrient agar medium, and Manitol salt agar medium are among the media used to cultivate bacteria. A variety of biochemical tests, including those using coagulase, citrate utilisation, oxidase, hemolysis, indole, catalase, and gramme staining, are performed to identify and characterise the morphological features of the microbial isolate. Fish skin is home to five distinct human bacterial infections, including Escherichia coli (E. coli), Pseudomonas, Klebsiella, Staphylococcus aureus, and Klebsiella epidermidis. Staphylococcus aureus, Cyprinus carpio, Hypothalmychthys molitrix, Tor putitora (T. putitora), and Wallago attu (W. attu) are isolated from the skin of Labeo rohita (L. rohita). Staphylococcus epidermidis is also discovered on W. attu and L. rohita's skin there. Spp.Pseudomonas, E. coli, and Bacillus-like Klebsiella are recovered from the skin of T. putitora, Hypothalmichthyes molitrix, W. attu, Cyprinus carpio, and L. rohita. It is believed that these bacteria are the source of fish spoiling at Peshawar's Ghanta-ghar fish market.In addition to causing fish to decay, the bacteria on fish skin also causes a number of serious illnesses in humans.
