“…On the other hand, (Montero et al, 2010). Dietary fish oil replacement by microalgae raw material gave SGR values between 1.3-1.5 in juvenile olive flounder (Paralichthys olivaceus) during 60 days of feeding (Qiao et al, 2014). Because our feeding trial was started from very early age (26 dah), SGR value was found higher in our study in comparison to other studies.…”

“…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).…”

“…Commercial microalgae products are still being developed in order to yield better quality and high content of essential nutrients, and they are considered promising alternative ingredients in feeds of larval and juvenile marine fish (Qiao et al, 2014). Microalgae production at commercial scale is highly required in aquaculture industry as well as in the newly developing biodiesel technology.…”

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...

“…This result is similar to observations reported on channel catfish (Li et al . ) and olive flounder Paralichthys olivaceus (Qiao, Wang, Song, Ma, Li, Liu, Zhang, Wang & Zhang ) fed the dried microalgae meal. The EPA levels in muscle decreased as dietary dried microalgae levels increased.…”

A feeding trial was conducted to assess the effects of dietary Schizochytrium meal supplementation on survival, growth performance, activities of digestive enzymes and fatty acid composition in Pacific white shrimp (Litopenaeus vannamei) larvae (initial body weight 4.21 ± 0.10 mg). Four isonitrogenous and isolipidic diets were formulated to contain graded levels of Schizochytrium meal: 0% (S0, the control diet), 2% (S2), 4% (S4) and 6% dry matter (S6). Results showed that there was no significant difference in survival of shrimps among dietary treatments (P > 0.05). Shrimps fed diets with 2% and 4% microalgae meal had significantly higher specific growth rate (SGR) than that of shrimps fed diets with 0% and 6% microalgae meal, and no significant differences were observed between shrimps fed diets with 2% and 4% microalgae meal (P > 0.05). Activity of trypsin in the pancreatic and intestinal segments, and activity of amylase in the pancreatic segments were not significantly affected by dietary microalgae meal levels (P > 0.05). Specific activities of both alkaline phosphatase and leucine‐aminopeptidase in intestine and purified brush border membrane of intestine were significantly higher in shrimps fed diet with 2% microalgae meal (P < 0.05). There were no significant differences in C18:2n‐6, n‐3 fatty acids, n‐6fatty acids, PUFA and n‐3/n‐6 in muscle samples among dietary treatments. C16:1n‐7, C18:1n‐9, MUFA, C18:3n‐3 and C20:5n‐3 decreased, however, C20:4n‐6 increased in the muscle as dietary microalgae meal level increased. In conclusion, 4% Schizochytrium meal in microdiets of shrimps can improve growth performance and may be a valuable additive in the microdiets of shrimps.

In the present study, the potential of the microalga Pavlova viridis (=Diacronema viridis) as an n-3 polyunsaturated fatty acid (PUFA) source was evaluated and compared to Nannochloropsis sp. in diets for juvenile European sea bass (Dicentrarchus labrax L.) (initial weight~12.8±1.7 g) in an 8-week feeding trial. Six different isoenergetic and isonitrogenous test diets were used: (1) fish oil diet (FO), major lipid source fish oil (100 %), (2) basal diet, 40 % fish oil and 60 % plant oil (in equal parts rapeseed, sunflower, and linseed oil), (3) Pavlova 50 % (P50), 50 % of the fish oil of the basal diet was substituted by lipid content of P. viridis meal, (4) Pavlova 100 % (P100), 100 % of the fish oil of the basal diet was substituted by lipid content of P. viridis meal, (5) Nannochloropsis 50 % (N50), 50 % of the fish oil of the basal diet was substituted by lipid content of Nannochloropsis sp. meal, and (6) Nannochloropsis 100 % (N100), 100 % of the fish oil of the basal diet was substituted by lipid content of Nannochloropsis sp. meal. The specific growth rate was highest and feed conversion ratio was lowest in the P100 group (SGR 1.77±0.10 % day −1 ; FCR 1.17±0.01), although not significantly different to the results for the FO and the other algae-groups. Furthermore, the sum of PUFA was also highest in the P100 group, followed by the P50, N100, N50, and B group (mainly due to the high content of linoleic and linolenic acids coming from plant oils and microalgal products) with the lowest levels in the FO group. The highest amounts of docosahexaenoic acid (DHA) of total fatty acids were found in the FO and B group, although not significantly higher than in groups P50 and P100. The significantly highest amount of eicosapentaenoic acid (EPA, % of total fatty acids) was in the P100 samples and the lowest amount was in samples of the basal group. The histological analyses of liver and intestine samples did not reveal any negative effects caused by the experimental treatments. Based on the basal diet, a 50 % fish oil replacement by Nannochloropsis sp. meal and a total replacement by P. viridis meal were possible without negative effects on the growth performance and nutrient utilization of juvenile sea bass.
