Abstract
Weaning period is the most critical period of eel life stages where high mortality rate occurred as a consequence to transfer into artificial diet .The study included two experiments to examine the pre-weaning diet and feeding methods effects on survival rate of eel fish.The first experiment examined the effect of beef liver (BL), tubifex worms (Tubifex spp.) (TW) and the mix (BL+TW) as pre-weaning diet on survival rate and weaning period.While, the  second experiment examined four feeding methods, aquarium bottom method (ABM), floating net method (FNM), rubber pipe method (RPM) and feeding chamber method (FCM) for their convenient for elvers feeding, survival and  limitation of feed loses. Results suggested that elvers fed (TW) observed for the highest survival rate and the longest weaning period.Feeding chamber method (FCM) is the most convenient for elvers feeding as recorded the highest survival rate and lowest feed losses.
