Effect of The Type of Solvent in Azolla Extracts Added to The Ratio on The Growth of Common Carp Cyprinus Carpio L

Abstract

Abstract The study was conducted in the fisheries laboratory of the Department of Animal Production in the College of Agriculture and Forestry/the University of Mosul. The experiment included feeding common carp fish using ten experimental diets containing azalea plant extract in proportions (0.5, 1, 1.5%) of each solvent, ether, acetone, and ethanol, and the control was free of additives. Glass tanks were used in the growth experiment of carp fish for a period of 49 days. The results of the statistical analysis of the final weight values, total and daily weight gain (gm/fish), and the relative and qualitative growth rate % showed that there were significant differences (P≤ 0.05) for the experimental treatments, and the third treatment (ether 1%) was significant compared to the rest of the treatments. While the results of the analysis of the amount of food consumed and the ratio of food efficiency in the presence.
