ABSTRACT
Two common fish Feeds; the locally made fish
feed and foreign fish feed (coppens) were diluted serially and cultured under
laboratory conditions for bacteria and fungi growth. The sub-culture and pure
cultures of the samples was obtained after which bacteria isolates was
characterized and identified. Determination of Bacterial count was carried out
using spread plate count. The result show that bacteria counts from local fish feed
was higher than the foreign fish feed and likewise the fungal count. The
isolated and identified bacteria include Escherichia coli, Staphylococcus
aureus, Enterococcus faecalis and Pseudomonas aureginosa. Sensitivity test
revealed that the gentamycin (antibiotic) had the highest zone of inhibition
18.0 on S.aureus. Out of the 12 samples that was cultured and examined, E. coli
and S. aureus was found mostly in both and very few in Enterococcus faecalis
and Pseudomonas aureginosa. 3 fungi found include Aspergillus, Fusarium, and
Rhizopus. This result shows that fish feeds sold in Umuahia have a higher range
organisms, this may be as a result of the storage conditions especially
unhygienic handling during storage. Long duration of storage should be discouraged
and improved storage conditions to prevent fish feed contamination by
microorganisms should be recommended.
