“…Palmitoleic acid was significantly higher in wild brown trout (7.24%) than cultured fish (3.74%). Similar results for wild and cultured trout have been reported (Akpinar, Akpinar, Gorgun, & Akpinar, 2015). Kaya & Erdem (2009) have also reported that oleic acid and palmitoleic acid are predominant MUFA in wild and farmed trout.…”

“…Linolenic acid (C 18:3 ω3), arachidonic acid (C 20:4 ω6), docosapentaenoic acid (C 22:5 ω3) and EPA values in the wild brown trout were significantly higher than cultured rainbow trout as shown in Table 1. Similar results were reported for wild and cultured trout (Akpinar, Akpinar, Gorgun, & Akpinar, 2015). Kaya & Erdem (2009), Fallah, Saei-Dehkordi, & Nematollahi (2011), Yeşilayer & Genç (2013 and Taşbozan, Gökçe, & Erbaş (2016) also reported that these fatty acids were higher in wild trout than rainbow trout.…”

“…The reason for these results may be the environmental factors. Various environmental conditions and diets affect the fatty acid composition of wild and reared fish (Akpinar, Akpinar, Gorgun & Akpinar, 2015;Blanchet et al, 2005).…”

“…Rainbow trout is primarily raised in inland waters and trout production has increased recently (Balcı Akova, 2015). Rainbow trout is the most important cultivated fish species in Turkey (Akpinar, Akpinar, Gorgun & Akpinar, 2015). This species is one of the most widely cultured species throughout the world (Kalyoncu, Yaman & Aktumsek, 2010).…”

Fish are a unique dietary source beneficial to human health. These valuable effects originate from ω3 polyunsaturated fatty acids, particularly the eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in the fish oil. In this study, fatty acid composition of the muscle lipids of Salmo trutta macrostigma (wild brown trout) and Oncorhynchus mykiss (cultured rainbow trout) in Gezende Dam Lake were determined by gas chromatographic technique. In both species, palmitic acid (16.26-18.94%), oleic acid (17.88-20.49%) and DHA (14.08-18.49%) were identified as major saturated fatty acid (SFA), monounsaturated fatty acid (MUFA) and polyunsaturated fatty acid (PUFA), respectively. Wild fish contained significantly more linolenic acid, arachidonic acid, eicosapentaenoic acid, docosapentaenoic acid, total ω3 fatty acids and has higher ω3/ω6 ratio than cultured fish. In conclusion, wild brown trout may have a higher nutritional value considering total ω3 fatty acids (35.52-27.43%) and ω3/ω6 ratio (3.84-1.56) compared to cultured rainbow trout.

“…Consumers are demanding more healthy, high quality, natural, and fresh fish products (Anonymous, 2007;Güler, Zengin, Çakmak, & Aktumsek, 2017), so fish oils containing essential fatty acids and polyunsaturated fatty acids are important for human health (Ateş, et al, 2013). It is known that rainbow trout (Oncorhynchus mykiss) is very important species and widely consumed in Europe (Çaklı, Klınıç, Dinçer, & Tolasa, 2006) and cultivated intense in various countries (Fallah, Saei-Dehkordi, & Nematollahi, 2011;Gall & Crandell, 1992;Gökoğlu, Yerlikaya, & Cengiz, 2004;Mashaie, 2001).…”

Development of defective fish egg sorting machine with colour sensor for trout facilities

The most important problem at the top of the list faced by trout producers is broken eggs. In this study, a further improved machine that is capable of distinguishing defective eggs from good ones with colour sensors is developed. The most important parts for the machine's operation are the colour sensor, a vertically rotating CD-like disk, a water spray valve, and a motor-pump to reuse the used water in the system. The process of separating robust and defective eggs from their own chambers uses a simple motor-driven spraying valve that produces a water gun level pressure. The water that these valves require is circulating within the system. Since the device uses a simple motor-pump and the PLC connected to the sensors draws low electrical currents, the energy consumption is also very low. The improved device has been tested in a trout production facility with a production capacity of 499 tons/year and has been observed to be successfully distinguishing the eggs.
