The samples weretransported directly to the laboratory with a minimum of delay to beexamined mycologically.’7.1 Fresh water fish. In fresh water fish, the mean values of contamination with moulds, 3 ’ ”and yeasts were 4.7 x 10.) ± lA x 10 and 7.1 x 10.) ± 3.6 x 10-,respectively. The mould genera isolated from fresh water fish wereAbasidia spp., Alternaria spp., Aspergillus spp. (which further identifiedinto A. flavus, A. fumigatus, A. niger and A. ochraceusy, Cladosporium,Fusarium spp., Mucor spp., Penicillium spp. and Rhizopus spp. while theyeast genera isolated were Candida albicans, Candida guillermondii,Candida tropicalis, Cryptococcus spp., Rhodotorula spp., Torulopsis spp.and Trichosporon spp.Frozen mackerel fishIn frozen mackerel fish, the mean values of contamination withmoulds and yeasts were l.3 x 103 ± 3.2 x 102 and 1.7 x 103 ± 3.6 x 102,respectively. The mould genera isolated from frozen mackerel fish wereAlternaria spp., Aspergillus spp. (which were further identified into A.flavus, A. fumigatus, A. gluacus, A. niger, A. terreus and A. versicolor),
