During 1980s and 1990s, demand feeders were not introduced into Egypt and in the same, the floating fish feed was not produced. Cage farmers invented this smart and effective feeder shown in the photo. The feeder is made of local materials which is already available for variety of purposes. Cage farmers introduced another simple method made of rope and roller to enable moving the feeder back and forth over the cage surface and lower it in under the water surface for 20-30 cm. This feeder is loaded with feed at the feeding place then moved to the right place in the center of the cage before lowering it under the water surface. Once the feed is consumed, the feeder is pulled back for reloading and so on depending on cage management. It may worth mentioning that the feed waste was at its minimum as indicated by Feed conversion ratio.
