“…This requirement of EPA sources in microdiets for gilthead seabream larvae was also shown in other studies (Atalah et al, 2007;Eryalçın et al, 2013). In this study, similar results to those obtained by the Control diet without any side effects on survival, growth, body and fatty acid composition of fish were obtained by the Mix diet, which contained both SBAE and Algamac products.…”

“…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).…”

“…Recently, several studies have been focused on n-3 LC-PUFA production from microalgae (Kyle and Gladue, 1991;Kyle et al, 1992;de Swaaf, 2003;Pulz and Gross, 2004;Ratledge, 2004;Spolaore et al, 2006;Ganuza and Izquierdo, 2007;Castillo et al, 2009) and its effectiveness on partial or complete replacement of fish oil in marine fish feeds (Mustafa et al, 1995;Navarro and Sarasquete, 1998;Miller et al, 2007;Atalah et al, 2007;Ganuza et al, 2008;Eryalçın et al, 2013). Microorganism produced n-3 LC-PUFA oils in marine feeds should be obtained by not only one species but also more than one microorganism species, in order to sustain better n-3 LC-PUFA composition and to create a wide range of fatty acid composition (Harel et al, 2002).…”

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...

“…These compounds include the primary metabolites needed for reproduction like proteins, lipids and carbohydrates, and secondary metabolites, which have diverse functions and chemical structures like flavonoids, terpenoids, and alkaloids. The rapid growth of some microalgae offers opportunities to continuously produce lipid-, starch-or protein-rich biomass, for example for aquaculture (Atalah et al, 2007;Ganuza et al, 2008;Hemaiswarya et al, 2011;Hussein et al, 2013;Velasquez et al, 2016).…”

AbstractMicroalgae have been studied as biofactories for almost four decades. Yet, even until today, many aspects of microalgae farming and processing are still considered exploratory because of the uniqueness of each microalgal species. Thus, it is important to develop the entire process of microalgae farming: from culturing to harvesting, and down to extracting the desired high-value products. Based on its rapid growth and high oil productivities, Nannochloropsis sp. is of particular interest to many industries for the production of highvalue oil containing omega-3 fatty acids, specifically eicosapentaenoic acid (EPA), but also several other products. This review compares the various techniques for induction, harvesting, and extraction of EPA-rich oil and high-value protein explored by academia and industry to develop a multi-product Nannochloropsis biorefinery. Knowledge gaps and opportunities are discussed for culturing and inducing fatty acid biosynthesis, biomass harvesting, and extracting EPA-rich oil and high-value protein from the biomass of Nannochloropsis sp.
