Özet
Doğal ve ağ kafeslerde yetiştirilen sarıkuyruk balıklarının et verimi, et rengi, besin bileşenleri ve yağ asitleri kompozisyonu araştırıldı. Doğal ve kültür sarıkuyruk balıklarının et verimi ve et rengi benzerlik gösterdi. Fakat doğal ve kültür balıklarının besin bileşenleri farklı bulundu. Doğal ve kültür balıklarının yağ asitlerinden C14:0; C20:2 n-6; C20:3 n-6; C20:5 n-3; C22:5 n-3 hariç diğer yağ asitleri önemli derecede farklılık göstermiştir. (P<0.05). Doğal ile kültür ortamında yetişen bu tür balıkları birbirinden ayırt etmede linoleik asit ve erüsik asit miktarlarının belirlenmesi önemli bir rol oynamaktadır. Doğal ve kültür sarıkuyruk balıklarında toplam n-3: n-6 yağ asitleri oranı sırası ile 5.5 ve 4.15 olarak bulunmuştur. Makro element seviyeleri doğal sarıkuyruk balıklarında kalsiyum hariç kültür balıklarından oldukça yüksektir. İz elementler içerisinde demir en yüksek oranda bulunmuş olup bunu çinko, bakır, baryum, kurşun, manganez ve kadmiyum takip etmiştir.
Meat yield, flesh colour, proximate and mineral compositions, and fatty acid profile of captured and wild greater amberjack were investigated. Meat yield and flesh colour of wild and cultured greater amberjack were similar. However, their proximate compositions were different. Most of the fatty acid composition of the wild and farmed fish were significantly different (P<0.05) from each other, except C14:0; C20:2 n-6; C20:3 n-6; C20:5 n-3; C22:5 n-3. The levels of linoleic acid and erucic acid were the key fatty acids discriminating cultured fish from the wild counterpart. The ratio of total n-3:n-6 fatty acid was 5.5 and 4.15 in the wild and farmed fish respectively. Macro elements level was much greater in the wild fish compare to cultured fish with the exception of calcium. Among the trace elements, iron was the foremost trace element followed by zinc, copper, barium, lead, manganese, and cadmium.
