Efficacy, cost and benefit of smoking fish using pit and chorkor technologies were investigated to inform decisions on economic sustainability and efficiency of the processing technologies in removing moisture content for quality assurance and extension of fish shelf-life. A total of 72 fresh fish; 36 (120 kg) Mormyrus caschive (Family: Mormyridae; common name: Elephant snout) and 36 (118 kg) Oreochromis niloticus (Family: Cichlidae; common name: Nile Tilapia) were bought from Sur-num fish landing site. From the procured fish, 12 (38 kg) samples were iced and used for fish moisture content analysis while the remaining 60 samples were divided into two batches for pit and chorkor smoking. Each batch contained 30 fresh fish samples with a total weight of 100 kg. Field experimental smoking was conducted twice in a completely randomized design. Moisture content in fish samples was determined using weight reduction method and cost benefit analysis using market price survey and interviews. Results revealed chorkor oven significantly reduce moisture content in M. caschive (10.0±0.83%) and O. niloticus (15.1±0.48%) more than pit kiln (15.3±0.57% and 17.3±0.42%), respectively. Although chorkor oven construction was expensive, the economic return was higher than for pit kiln due to short smoking time (6-8 hours, and twice in 24 hours) and utilization of small quantity of firewood (4 bundles/round). Chorkor oven is therefore, an efficient and economically viable technology for smoking fish. The study recommends its adoption for artisanal fisheries in South Sudan.
