In: Agricultural Research Journal, Suez Canal University 2011 v.11(2)Summary: The potential effect of selection for growth and related traits of Nile tilapia Oreochromis niloticus on disease resistance and a variety of specific and nonspecific immune parameters was investigated between two different lines of 0. niloticus (selected bred line SBL derived from the 8th generation selected for increased body weight at harvest and a random bred line RBL), via an experimental challenge through the intraperitoneal route with Aeromonas hydrophila. Prior to challenge; SBL showed observed enhancement of survival rate and significant increases (P < 0.05) of growth performance compared to RBL group after a rearing period of 180 days in circular earthen ponds. Mortalities due to challenge were higher in RBL group than those recorded in SBL group, SBL group revealed significant increases in the hematological indices than the RBL group,
