    Abstract: Soil erosion is more sensitive in the highlands of Ethiopia. The purpose of this study is evaluating erosion risk potential using RUSLE model with GIS and remote sensing to identify erosion potential areas for soil and water resources conservation plan and to prepare soil loss risk map. Collected data were processed and analyzed using Arc GIS10.2 v... Show More

    Abstract: In this study, shrimp feed was substituted with a dried alga, Schizochytrium sp., at five levels (0, 10, 20, 40, and 60% of compound feed) to yield protein/energy (P/E) ratios of 22.72, 19.75, 16.71, 13.72 and 10.75 mg protein/KJ, respectively. The effects of this substitution on the specific growth rate (SGR), survival rate, fatty acid composition... Show More
