AB  - A 45-day feeding trial was conducted to study
the effects of Safmannan as feed additive for African
catfish (<i>Clarias gariepinus</i>, Burchell) fingerlings. Total of
270 catfish fingerlings were randomly distributed into
nine experimental aquaria. Three complete diets were
used in this study: Diet 1, feed from company A (control);
Diet 2, feed from company B; Diet 3, feed from company
B supplemented with Safmannan. Each of the diets was
fed to triplicate groups of fish. The results showed that
fish growth was not significantly (p>0.05) affected by
diets, even with the supplementation of Safmannan. The
feed conversion ratio of catfish fed with Diet 1 was
significantly (p<0.05) lower than those fed with Diet 2 but
not significantly different from catfish fed with
Diet 3, reflecting the competitiveness of Safmannansupplemented
feed to the control feed. Fillet of catfish fed
with Diet 2 had significantly higher crude protein content
than those fed other two diets while significantly lower
crude lipid content was resulted in the fillet of catfish fed
with Diet 2 and Diet 3. Interestingly, Safmannan
supplementation significantly lowered the colony forming
unit count and increased serum lysozyme activity. In
conclusion, Safmannan could be used as an
immunostimulant for catfish farming.
