The growth response of Tilapia fish (Oreochromis niloticus) to supplementation with fresh or dried leaves of a sweet variety of cassava was studied in 1 m deep ponds (each 4 m * 2.5 m * 1 m). Rice bran or rice bran mixed with cassava root meal was provided as the energy source (20-24% of feed DM), the mixed feed being given at the rate of 5% of fish LW. There were 30 fish per pond with average initial weight of 6 g per head. The treatments were arranged as a 2*2 factorial in a Completely Randomized Design (CRD) with 4 replicates. The first factor was cassava leaf processing (sun-dried or fresh); the second factor was energy source (rice bran or rice bran mixed with cassava root meal). The cassava leaves and roots were from a local “sweet” variety traditionally planted by farmers for human consumption. The experiment was conducted for 100 days. Daily gain in weight and length, and the ratio weight: length after 100 days of growth, did not differ among treatments. All the fish survived and there was no evidence of HCN toxicity. Water quality parameters were not affected by the treatments. There were no interactions between sources of protein and of energy. It is concluded that the feeding of cassava leaves with rice bran can be readily adopted by small scale farmers as both these feed resources are readily available in rural areas.

This case study was conducted to generate insights on the financial sustainability of selected VDFSGs and to gather information on members’ perceptions of the usefulness of these institutions in coping with household and climate change-related shocks or stresses. Financial sustainability was analyzed by conducting a detailed financial analysis of six selected VDFSGs to determine the sufficiency of interest payments as revenue to cover total costs as well as to evaluate loan recovery and equity build- up. Members’ perception of the usefulness of VDFSGs in helping them to cope with and adjust to family and climate change-related shocks/stresses was determined by conducting Focus Group Discussions (FGDs) and Key Informant Interviews (KIIs) among selected representatives of VDFSG members. Useful feedback of the financial performance and areas for improvement were generated. The Pu Hong, Pu Chhob, and Prek Svay VDFSGs were considered financially sustainable based on the results of the study. The study also revealed that the VDFSGs are considered most useful when there are crop failures due to extreme weather events and when there are medical emergencies in the household. The FGD participants and key informants expressed confidence that they are in a better position to cope with their vulnerabilities due to the presence of a VDFSG in their village.
