Abstract
The purpose of this study was to assess cultural energy (CE) use and energy use efficiency of a commercial small scale rainbow trout (Oncorhynchus mykiss) cage farm in the inland waters in Karacaören Dam Lake, Isparta, Turkey. Data collected for each production year were: number and total weight of fingerlings, amount of feed consumed, amount of antibiotics, vitamin, labor, diesel, oxygen used, number and total weight of marketed trout, distance for transportation of fingerlings, machinery, and equipment with their depreciation rate. Total CE use was the sum of CE expended on feed, general management, transportation, machinery, and equipment. CE expended on compound diet constituted 77.78% of total CE. CE expended for a kg of liveweight gain was 2.68 Mcal. Protein energy production efficiency in carcass and fillet was 4.28 and 7.44 Mcal, respectively. CE energy use efficiency for carcass and fillet were 4.19 and 6.85, respectively. Results showed that in order to compare the sustainability of aquaculture production systems energy use efficiency which is an indicator of sustainability should be determined.
