A formulated fish feed was fermented with amylase producing Bacillus cereus (Sn-1 and Sn-3) and Proteus mirabilisis -Sn-2 employing solid state fermentation (SSF) at their corresponding optimized growth conditions. SSF of the fish feed indicated significant increase and decreases in glucose and starch contents within seven days, respectively. Significant elevations also occurred in protein levels as compared to the corresponding values of non fermented control feed. The protein levels increased up to 42.27% by B. cereus-Sn-1 after 24 hours, 63.16% by P. mirabilis-Sn-2 after 168 hours and 47.47% by B. cereus-Sn-3 after 168 hours of incubations. These bacterial isolates caused the nutritional increments with 10% inocula and 70% moisture contents. The C.F.U./g of fermented feeds paralleled, in general, the feed nutritional enrichment. These results are reminiscent to design commercial level solid state fermentation facilities for developing the aquafeed industry in this country.
