Abstract

The study was aimed at evaluating proximate, microbial, and heavy metals of processed Brycinus nurse and Oreochromis niloticus. Fresh B. nurse and O. niloticus weighing 16kg of 8kg per species were obtained from fishers at Gubi dam. They were washed and gutted. Each 8kg of fish species was divided into two equal parts of 4kg each. The fish samples were randomly allocated to four treatments in complete randomized design:B.  nurse fermented with salt (BFS) and without salt (BFWS);O. niloticus fermented with salt (NFS) and without salt (NFWS). Fermentation of the fishes was carried out by splitting the 4kg of each fish species into 2kg and was placed manually into four airtight transparent glass bottles, buried in four holes of 1m deep in the soil for four weeks.B. nurse(SMB) and O. niloticus(SMN)samples weighing 4kg each were salted, dried, and smoked. The mean proximate analysis values were BFS had the highest moisture content (78.98%); BFWS had the least (55.10%); SMB had the highest crude protein (60.12%); NFWS had the least (4.66%). SMB had the highest 14.08%ash while NFWS had the least (3.65%). SMB had the highest 10.29% extract ether while NFS had the least (1.22%). NFS had the highest 1.40% crude fibre while SMBhad the least (0.29%). Fresh B. nurse recorded the highest 1.70 x 107 and 8.80 x 107 cfu/g mean bacteria and fungi counts respectively. BFWSrecorded the highest mean values of 2.05±0.05mg/kgand 0.88±0.02mg/kg for Zn and Pb respectively
