U.N.Ekwenye, J.O.Ugwoeje

Samples of sediment, fishfeed, pond water and tilapia(Oerochromis niloticus) fromtheMichael Okpara University fish culture pond were examined for fungal quality. The samples were colleted using sterile bottles for the sediment, pond water, and fish feed samples, and a bucket for colleting the fish sample. The samples were homogenized and cultured on Potato Dextrose Agar. Results revealed that the fungal load of fishfeed was higher than that of the sediment with pond water having the lowest fungal load. The isolated fungi were Aspergillus niger, Cladosporium herbarum, Fusarium(Hyalophragmiae), Penicillium notatum, Yeast (Mycoderma), Rhizopus nigricans andMucor. Some precautionary measures were recommended such as regulating and inspecting the water quality of the pond to avoid spread of pathogens, removing an infected fish to an isolation tank which serves as a hospital for immediate treatment, application of medications, adequate stocking and fertilization of the pond.
