Abstract
Fish remains a crucial component of human nutrition, providing essential high protein and mineral content for survival. This study, conducted in Ketu Adie-Owe, Ado Odo Local Government Area of Ogun State, Nigeria, aims to isolate and comprehend fungal pathogens in pond catfish ecosystems. Three male Clarias gariepinus fish samples were collected from a concrete fish pond in Apena Village, Ketu, Igbesa, and transported aseptically to the Microbiology Laboratory at Crawford University for microbiological analysis. Sabouraud Dextrose Agar with chloramphenicol, to inhibit bacterial growth, was prepared for the isolation of fungi following the manufacturer’s instructions. Skin and intestine samples from each fish were processed, leading to the identification of various fungal species, including yeast and mold types. Notable isolates included Trichosporon spp., Malassezia (yeasts), Fusarium oxysporum, and Arthroderma quadrifidum (molds), each potentially contributing uniquely to the pondwater ecosystem. Understanding these isolates is important due to their potential to harm fish health, reduce marketability, and pose health risks to humans and animals. The study raised concerns about possible water contamination in the catfish pond, highlighting the risk of fish infections under such conditions. The research also underscored the ecological importance of fungi in pond catfish ecosystems, particularly in nutrient cycling and organic matter decomposition. The presence of pathogenic fungi emphasizes the need for vigilant monitoring and management to protect fish health, aquaculture productivity, and public well-being
