A study of the mycoflora of three fish species: Lutjanus
agennes (Red Snapper), Mugil cephalus (Mullet), Chrysichthys
walkeri (Catfish) smoke-dried using Rubber wood (Hevea
brassillensis) was carried out. Fish samples were bought
from Ogbe-Ijoh market in Warri, Delta State and smoked using
a traditional rectangular mud kiln (Chorkor) and stored on
open benches in the laboratory at room temperature. Samples
from the smoke-dried fish species were assessed tri-weekly
using amended potato dextrose agar during the period of
storage. Moisture content of the fish samples varied with
storage time but was not significant (P> 0.05). The highest
mean fungi count of (1.08 x106, 8.0 x 105
and 1.16 x 106) cfu/g was recorded in the gills,
muscle and skin of Chrysichthys walkeri during the six weeks
of storage. There were significant differences (P<0.05) in
the mean fungi counts in the three anatomical parts among
the fish species. The predominant fungi species isolated
from three different anatomical parts of smoke-dried fish
samples during storage was made up of six (6) genera of
fungi. Saccharomyces (37.69%), followed by Penicillum
italicum (20.29%), Penicillum oxalicum (17.39%), Mucor sp
(10.15%), Rhodotorula sp (7.25%), Aspergillus sp (5.79). The
study has shown that fish samples could still be consumed
after six (6) weeks of storage but were heavily contaminated
with micro-organisms and could pose a serious health concern
for consumers.
