“…This finding is consistent with previous studies showing successful partial or total replacement of dietary fish oil with vegetable oil in African catfish [25][26][27], rainbow trout [28], sharpsnout sea bream [29] and Atlantic salmon [30,31] without showing any negative impact on growth.…”

“…Increased hepatic lipid deposition is commonly associated with the morphological alteration known as steatosis, which is due to increased synthesis and deposition of triacylglycerols in hepatocytes vacuoles (Montero and Izquierdo 2010). In many instances, when n-6 PUFA rich alternative oils were used to replace fish oil, the modification of hepatic lipid content and hepatic histological/morphological alterations were recorded (Caballero et al, 2004;Wassef et al, 2007;BeneditoPalos et al, 2007;Piedecausa et al, 2007;Leaver et al, 2008). Conversely, Figueirdo-Silva et al (2005) showed that replacing dietary fish oil with soybean oil was not responsible for any significant modification on hepatic lipid droplets accumulation in European sea bass.…”

Triplicate groups of 20 European sea bass (35 g) were fed five diets in which the added lipid was 100% fish oil (FO), 40% (CSO40), 60% (CSO60), 80% (CSO80) and 100% (CSO100) refined cottonseed oil (CSO), for a period of 120 days. Overall fish growth, feed conversion ratio and protein utilization were unaffected by dietary treatment, but hepatosomatic and visceral fat indexes increased with increasing dietary CSO. Fillet fatty acid composition of total lipids reflected the fatty acids in the test diets. The monounsaturated fatty acids were significantly higher in fillet of fish fed diet FO, CSO40 and CSO60 compared to other treatments while saturated and polyunsaturated fatty acids (PUFA) were not affected by the dietary treatment. Some fatty acids (18:0, 18:1n-9, 20:5n-3 and 22:6n-3) were present in higher concentration in fillet lipid than in the CSO100 dietary lipid indicating accumulation in fillet relative to test diets. Retention of n-3 LC-PUFA within the fillet was increasingly inefficient among fish fed increasing levels of FO. Thus, this study suggests that CSO can be considered as a relatively effective substitute for fish oil in European sea bass (35 g) in terms of growth performances and feed efficiency as far as fish meal is present in the diet.Keywords: Dicentrarchus labrax, linoleic acid, fish oil replacement, aquafeed, vegetable oils. Avrupa Deniz Levreği Yem Formulasyonunda Pamuk Tohumu Yağının Potansiyel olarak Balık Yağına İkamesi ÖzetYirmi adet Avrupa deniz levreği bireyi (35 g) 120 gün boyunca %100 balık yağı (BY), %40 Pamuk Toplama Yağı(PTY40), %60 (PTY60), %80 (PTY80) ve %100 (PTY100) oranlarında rafine edilmiş pamuk tohumu yağı (PTY) ilave edilmiş beş yemle beslenmiştir. Balık büyümesi, yem çevirim oranı ve protein değerlendirme yem uygulamasıyla değişmezken, hepatosomatik ve visseral yağ indeksi yemdeki PTY'nin seviyesiyle artmıştır. Fileto toplam lipit yağ asidi kompozisyonu test yemlerinin yağ asidi kompozisyonuna yansımıştır. BY, PTY40 ve PTY60 ile beslenen bireylerin fileto tekli doymamış yağ asidi miktarı diğer gruplara göre daha yüksek iken doymuş (DYA) ve çoklu doymamış yağ asitleri (ÇDYA) miktarı etkilenmemiştir. Test yemleri göz önüne alındığında, PTY100 grubu bireylerinin fileto yağlarında bazı yağ asitleri (18:0, 18:1n-9, 20:5n-3 ve 22:6n-3) yüksek oranda birikmiştir. Filetodaki uzun zincirli n-3 ÇDYA'lerin birikimi artan balık yağı oranı ile beslenen balıklarda yetersizdir. Bu çalışma, yemlerde balık unu kullanıldığı sürece, büyüme performansı ve yem değerlendirme açısından Avrupa deniz levreği (35 g) için PTY'nin balık yağını ikame edilebileceğini önermektedir.Anahtar Kelimeler: Dicentrarchus labrax, linolenik asit, balık yağı değişimi, yem, bitkisel yağlar.

“…Dietary fish oil replacement by terrestrial plant oils (Bell et al, 2003;Bransden et al, 2003;Şener et al, 2006;Huang et al, 2007;Piedecausa et al, 2007;Fountoulaki et al, 2009;Bell et al, 2010) and alternative microorganism oils have been extensively studied in marine fish feeds (Miller et al, 2007;Atalah et al, 2007;Eryalçın et al, 2013;Qiao et al, 2014;Sprague et al, 2015). Total fish oil substition by vegetable oils in sharpsnout sea bream (Diplodus puntazzo) and red sea bream (Pagrus major) did not negatively affect growth of those fish, suggesting that the respective essential fatty acids requirements were met by dietary lipid source (Glencross et al, 2003;Piedecausa et al, 2007).…”

The aim of the present study was to investigate the effects of replacing fish oil by different microalgae products on the growth performance and fatty acid composition of gilthead sea bream (0.02±0.00 g) during 90 days of post larvae and weaning period. Four diets were evaluated: control diet was exclusively based on fishoil; SBAE diet included the commercial product SBAE ® , which consists of four microalgae: Tetraselmis suecica, Isochrysis sp., Nannochloropsis oculata and Phaeodactylum tricornutum; Algamac diet included the commercial product Algamac 3050, which consists solely of the microalgae Schizocthytrium sp., and Mix diet that consisted of a mixture of both commercial products in equal amounts, SBAE ® and Algamac ® . At the end of the feeding trial, the highest weight gain was obtained in Control (1.34±0.00 g) and Mix (1.34±0.03 g) groups (P<0.05). The highest survival rates were found in Control and Mix diet groups, whereas the lowest was found in SBAE diet group. Experimental diets showed significant effects on the fatty acid composition of larvae. The total long-chain n-3 polyunsaturated fatty acid (LC-PUFA), eicosapentaenoic acid and docosahexaenoic acid levels were increased with inclusion of microalgae products. Based on the results of growth performance and fatty acid composition, fish oil substitution by a blend of equal amounts of microalgae products SBAE ® and Algamac ® 3050 seems to be promising in weaning diets for gilthead sea bream larvae.Keywords: Gilthead sea bream, nutrition, microalgae, growth performance, survival, essential fatty acids. Kurutulmuş Mikroalg İçeren Mikrodiyetler ile Uzun Süreli Beslenmenin, Çipura (Sparus aurata, L.,1758)' larda Büyüme ve Yağ Asidi Kompozisyonuna Etkileri ÖzetBu çalışmanın amacı, çipura (0,02±0,00 g) post larval ve ön büyütme döneminde 90 gün süresince balık yağı yerine farklı mikroalg ürünleri kullanılmasının, büyüme performansı ve yağ asidi kompozisyonuna olan etkilerinin incelenmesidir. Kontrol yeminde yağ kaynağı olarak sadece balık yağı kullanılmıştır; Tetraselmis suecica, Isochrysis sp., Nannochloropsis oculata ve Phaeodactylum tricornutum olmak üzere 4 mikroalg türünden oluşan SBAE ® ticari ürünü içeren SBAE yemi; sadece mikroalg Schizocthytrium sp.'den oluşan ticari Algamac 3050 ürünü içeren Algamac yemi ve her iki ticari ürünün eşit oranlarda karışımını içeren Mix yem olmak üzere toplam dört farklı deney yemi kullanılmıştır. Besleme deneyi sonunda, en yüksek ağırlık kazanımı Kontrol (1,34±0,00 g) ve Mix deney (1,34±0,03 g) gruplarında gözlenmiştir (P<0,05). En yüksek hayatta kalma oranları da Kontrol ve Mix gruplarında bulunurken, en düşük değer SBAE grubunda görülmüştür. Deneysel yemler, yavruların yağ asidi kompozisyonları üzerinde etkili olmuştur. Toplam uzun zincirli n-3 çok doymamış yağ asitleri (LC-PUFA), eikosapentaenoik asit ve dokosahekzaenoik asit seviyeleri, mikroalg ürünlerinin kullanılmasıyla artış göstermiştir. Büyüme performansı ve yağ asidi kompozisyonu sonuçlarına dayanarak, balık yağı yerine eşit oranlarda SBAE ve Alg...
