The production of single cell protein (SCP) is one of the cheap protein sources for use in aquaculture. In this study, Claveromycice frajilice and Fusarium oxysporum were used to produce SCP using Kilka stick water as the source of medium. Adaptation of C. frajilice and F. oxysporum to pure stick water was performed by increasing the concentration of stick water in distilled water. Treatments included 50% and 100% stick water, and a group without stick water as control. The pattern of the yeast and fungus growth was studied by spectrophotometry at 600 nm. The final product was analyzed for values of dry materials, amino acids profiles, total protein, moisture and ash. The results showed protein production by C. frajilice in 50% and 100% stick water was 55.35% and 57.47%, respectively, compared to 54.65% in control group (P>0.05). Protein production using F. oxysporum was 53.17% and 54.39±0.45% in 50% and 100% stick water, respectively compared to 49.71% in control group (P>0.05). The results showed that amino acids composition in produced SCP was comparable with the suggested profiles of requirement by FAO/WHO and NRC. Based on to the obtained results, application of pure Kilka stick water is suitable for production of C. frajilice as the source of SCP.
