Abstract: An experiment was conducted by using "Canna" stick Oxytenanthera abyssinica as a locally available material for fish cages construction and to evaluate the benefits and performance in the water body of El-Rahad Lake "Torda" in Northern Kordofan-Sudan. Stalks plant of "Canna" were shaped the frame of three fish cages of 1.2×1.2×1.2m in size (fish cages type "A"), compared with another set of three fish cages with the same size made of iron frame considered as a control cage type (fish cages type "B")."El-Taror" shine (Aeschynomeneela phroxylon) used as a floaters in both cage types. The results of the study showed that the possibility of using "Canna" for external frameworks of fish cages and a validity of "Canna" sticks in water in good condition for more than 70 days, as the study indicated a well efficiency of "Canna" sticks in carrying the changing of the environmental factors as winds, waves, water currents, relative humidity, solar radiation during the study period, with the necessity of a good hedge in installed sticks of "Canna" together. Moreover, the study showed a significant low cost (P<0.05) of constructing fish cage from "Canna" sticks and "El-Taror" shine as a locally available material (200SP), compared with the cost of construction of iron made cage frame (310SP). The study notes the wonders of the local fishermen and residents in the region with the idea of owning a small fish cage made from locally available materials to breed and produce tilapia fishes.
