Microbial load and Proximate Composition of Fresh Nile Tilapia (O .niloticus) Collected from Different Market at Khartoum State.

Abstract

This study was designed to investigate the proximate composition and the bacteria load on the gills, skin and intestines associated with fresh Nile tilapia (Oreochromis niloticus) wear collected from different markets of Khartoum State during summer season,.
