Pre-extension demonstration of Nile tilapia (Oreochromis niloticus) fingerling multiplication method in selected site of East Showa Zone, Oromia Regional State, Ethiopia.

This innovative way of Nile Tilapia (Oreochromis niloticus) fingerling multiplication method was conducted in Bora District of East Showa zone, Oromia, Ethiopia. For this purpose two ponds (6m x 8m) were prepared with the same size. One pond is hapa based and the second one without hapa based which is conventional method of fingerling production. Each hapa was stocked with 4 male and 8 female brood stocks, finally 3600 fingerling having good performance were counted with good status. Totally from the stocked four hapa a total of 14,400 fingerlings was produced within one breeding cycle. In average one female brood stock produced 450 eggs with in one time breeding section. In similar way the data was taken from the second open ponds. From this pond a total of 12,500 fingerlings harvested with in the same time and the same number of brood stock. Eventually training was given for a total of 34 participants and demonstrated the result of the activity to the participated farmers, experts and researchers. The demonstration result shown that, there was statistically significance difference between the improved and traditional fingerling multiplication methods. Therefore, hapa based method of fingerling multiplication technology was recommended for scaling up at similar agro ecological regions.
