Abstract
Proximate composition of two freshwater fish species (Clarias gariepinus and Oreochromis niloticus), caught from River Rima were examined. The results revealed variation in nutrient composition, crude protein content ranged from 17.95 to 35.44% in flesh, bones and heads.  arias gariepinus has the highest moisture content of 22.5% than Oreochromis niloticus with 9.50% in flesh parts. Clarias gariepinus has the highest crude protein of 35.44%. The study provides valuable information of Clarias gariepinus and Oreochromis niloticus status on their proximate composition.

Abstract
The present study was conducted to evaluate the in vitro antimicrobial activity of commercial extracts of Salvia officinalis L. against Coliformes spp., Pseudomonas spp., Saccharomyces cerevisiae, Zygosaccharomyces bailii and Lactobacillus plantarum. Antimicrobial activity of extracts was investigated on the basis of Inhibition zones (IZ) measurement by Agar well diffusion method at concentrations of 10, 50 and 100 ppm. Extracts exhibited IZ between 0 and 4.3 mm against the five tested microorganisms. Maximum inhibition (4.3 mm) was shown by 10 ppm of this oil against Z. baillii, while 100 ppm was inactive against Coliforms spp. and Z. baillii. Coli forms spp, Z. baillii and Pseudomonas spp. were more sensitive to the oil than S. cereviceaeand L. plantarum.
