This experiment has been performed to assess the effect of partial substitution of fishmealwith lentil seeds in common carp growth performance, feed utilization and certain biologicalparameters (Fulton condition, Hepatic somatic index, Gills somatic index, Kidney somatic index,Spleen somatic index, Intestine Length index, Intestine weight index). Fish from a private fishfarm were acquired in province of Sulaimaniyah, Iraq. Average fish weight ranged from 95-99gm. Fish were divided into 5 treatment groups. The treatments were: T1: In fish diet 0% lentilseed was replaced with fishmeal, T2: In fish diet 5% lentil seed was replaced with fishmeal, T3:10% lentil seed was replaced with fishmeal, T4: 15% lentil seed was replaced with fishmeal, T5:20% lentil seed was replaced with fishmeal. There had been significant differences in weightgain, daily, relative, and specific growth rate as lentil seed replaced with fishmeal in fish diet.Feed Efficiency Ratio, Protein Efficiency Ratio and Fat Efficiency Ratio was significantly higherin T5 group than that of the other treated groups. No significant differences in the mean values ofHepatosomatic index, Spleensomatic index and Kidneysomatic index were detected. Significantdifference in the mean value of Condition Factor was found among treatment groups. Intestinelengthindex was significant among treatment groups according to fish weight while mean value showed non-significant cording to fish length. The performance and general health of thecommon carp were significantly improved by raw lentil seed. Due to their low price incomparison to fishmeal and commercially available in all markets, it is suggested to substitutethe fishmeal with raw lentil seed in commercial fish diet.
