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.

土耳其内陆水域小型虹鳟鱼(Oncorhynchus mykiss Walbaum, 1792)笼养鱼场的文化能源利用和能源利用效率:Karacaören-I大坝湖的案例研究

本研究的目的是评估土耳其伊斯帕塔Karacaören坝湖内陆水域商业小规模虹鳟鱼(Oncorhynchus mykiss)网箱养殖场的养殖能源(CE)利用和能源利用效率。每个生产年收集的数据包括:鱼种数量和总重、饲料消耗量、抗生素、维生素、人工、柴油、氧气用量、市售鳟鱼数量和总重、鱼种运输距离、机械和设备及其折旧率。总能源消耗是消耗在饲料、一般管理、运输、机械和设备上的能源消耗的总和。复合日粮消耗的CE占总CE的77.78%。每公斤活增重消耗的CE为2.68 Mcal。胴体和鱼片蛋白质能生产效率分别为4.28和7.44 Mcal。胴体和鱼片的CE能利用效率分别为4.19和6.85。结果表明，为了比较水产养殖生产系统的可持续性，应确定作为可持续性指标的能源利用效率。
