“…C. cohnii, distributed world-wide, is a marine heterotrophic microalga (dinoflagellate) (Beam and Himes, 1982). Until recently, studies of C. cohnii have focused on cultivation (Pleissner and Eriksen, 2012;Hillig et al, 2013), DHA production (Gong et al, 2015), the biological activity of DHA (Fedorova-Dahms et al, 2014), and DHA applications in the breeding and aquatic industries (Schiavone et al, 2007;Ganuza et al, 2008). Schizochytrium sp.…”

“…belongs to the Stramenopila (thraustochytrid) kingdom and generally lives in marine habitats throughout the world (Lippmeier et al, 2009;Fedorova-Dahms et al, 2011). Many studies have been concerned with cultivation optimization (Ling et al, 2015;Guo et al, 2016), safety evaluation of the algal oil (Lewis et al, 2016), and applications in the aquatic product industry (Ganuza et al, 2008;Li et al, 2009). To date, there have been only limited reports examining the antioxidant activity of these two microalgae.…”

Abstract:Crypthecodinium cohnii (dinoflagellate) and Schizochytrium sp. (thraustochytrid) are the main sources for docosahexaenoic acid (DHA). The present study aimed to evaluate the antioxidant activity of petroleum ether, ethyl acetate, n-butanol, and water fractions of alcohol aqueous extracts of these two microalgae and to provide a theoretical basis for comprehensive utilization. The antioxidant activity was determined by total antioxidant capacity (TAC) determination, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay, ferrous ion-chelating ability (FICA) assay, and reducing power (RP) assay. The total phenolic content (TPC) and total flavonoid content (TFC) were also measured by the Folin-Ciocalteu and spectrophotometry methods, respectively. The results indicated that the extracts from these two microalgae possessed good antioxidant capacity. Analysis showed that most antioxidant performance indicators (TAC, DPPH, and RP) were positively correlated with the TPC of the extracts, suggesting that the phenolics might be the major components in C. cohnii and Schizochytrium sp., contributing to their antioxidative function. Therefore, the polar fractions of C. cohnii and Schizochytrium sp. could be further examined and considered for application in health products or cosmetics.

“…Different microalgae products have been studied for completely replacing fish oil in microdiets without any side effects on survival, growth and health of marine fish (Navarro and Sarasquete, 1998;Lazo et al, 2000;Harel et al, 2002;Miller et al, 2007;Li et al, 2009Eryalcin et al, 2013.The vital effect of EPA content on growth and survival was previously suggested by Ganuza et al (2008) who concluded that DHA rich single cell microorganisms in microdiets cannot replace completely fish based products. 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).…”

“…Unlike marine microorganism oil sources, terrestial plant oils lack of n-3 LC-PUFA and several negative effects may occur on survival, growth performance, flesh quality and taste parameters of fish fed these diets, including gilthead sea bream (Montero et al, 2008). Marine microorganism produced oil such as microalgae oil were successfully used as lipid sources substituting by fish oil in fish feeds without any hazardous effects (Ganuza et al, 2008;Eryalçın et al, 2013).…”

“…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...

Aquaculture is the fastest growing food production sector and is expected to provide over 60% of the world's seafood by 2030. Lipids represent the major energy contribution in aquaculture nutrition, and as such, reach high inclusion levels in energy–dense aquafeeds. Lipids are a prominently studied nutrient in aquaculture, since they supply energy and essential fatty acids and because of the unique abundance of the ω3 long‐chain polyunsaturated fatty acids that are found in fish. Lipids from fish are well known to have positive impacts on human health, and as such, the transfer of lipids from the diet to fish to consumer is of great importance. Therefore, the fats and oils that are supplied for the health, growth, and development of aquaculture fish must be of good quality and sourced sustainably for the future of aquaculture production. This article describes the role of fats and oils in aquafeeds. In order to understand how the fats and oils are utilized, this article reviews the lipid and fatty acid requirements, lipid digestibility, and lipid synthesis of aquaculture fish. It also describes the most common fats and oils that are used in aquafeed formulations, as well as novel, innovative lipid sources, and new methods of formulating fatty acids in aquafeeds. The different lipid and fatty acid compositions of these fat and oil sources in the diet can directly impact the nutritional and product quality of farmed fish. The practical consideration for using high levels of dietary lipid in aquafeeds is the feed quality, particularly considering lipid oxidation.
