“…This blunted response to stress was very similar to what was found in seabream larvae exposed to another type of acute stress. Both 28-and 50 days post-hatch larvae showed considerable lower peak cortisol levels when they were fed ArA-enriched Artemia nauplii prior to a brief exposure to air (Van Anholt et al, 2004). These observations in seabream are in complete contrast to the augmented cortisol response observed in tilapia Oreochromis mossambicus, when fed the same diet enriched with ArA (R.D.V.A., F.A.T.S., W.M.K.…”

In this study the influence of the dietary level of the fatty acid arachidonic acid (ArA, 20:4n-6) was determined on the acute stress response and osmoregulation of adult gilthead seabream Sparus aurata L. Seabream were fed a diet containing either 0.9% or 2.4% of total fatty acids as ArA for 18 days before being subjected to a 5·min period of net confinement. Prior to this stressor, a subgroup of fish from both dietary treatment groups was treated with acetylsalicylic acid (ASA), an irreversible blocker of cyclooxygenase (COX). This would indicate whether any effects were caused by an enhanced synthesis of prostaglandins derived from ArA. The highest ArA levels were found in the kidneys, and these were further enhanced by dietary ArA-supplementation. In gill tissues, there were significant changes in all selected fatty acid classes 24 h after confinement, except for the docosahexaenoic acid (DHA, 22:6n-3) : eicosapentaenoic acid (EPA, 20:5n-3) ratio. ArA feeding strongly reduced the cortisol response to confinement, which was partially counteracted by ASA treatment. ArA also attenuated the stress-associated increase in plasma osmolality and, in combination with ASA, enhanced the osmolality and plasma chloride levels, but reduced plasma sodium levels after confinement. Furthermore, ArA enhanced the branchial Na + , K + -ATPase activity both before and after confinement, whereas feeding ASA diminished this effect. It appeared that the effects of ArA-supplementation could not always be ascribed to an increase in prostaglandin synthesis. It is advisable to determine the long-term effects of replacing fish oils in commercial diets with vegetable oils that contain no long-chain fatty acids, particularly in carnivorous/marine species with low fatty acid elongation and desaturation activities. The effects of a low dietary intake of ArA (and other polyunsaturated fatty acids) should be studied over a longer term, taking into account any consequences for the health of the fish.

“…Several studies have found indications that ArA, and other PUFA, are involved in the regulation of cortisol release in fish as well (Gupta et al, 1985;Wales, 1988;Harel et al, 2001;Koven et al, 2003). Moreover, dietary supplementation with ArA clearly reduced the cortisol response of seabream larvae to air exposure (Van Anholt et al, 2004).…”

“…When similar studies were carried out in larval sea bream, 20:4n-6 again reduced the cortisol response and increased survival of fish subjected to air exposure stress. But in this case, feeding 20:4n-6 increased the stress response when subjected to salinity stress, thus reducing growth and survival Van Anholt et al 2004a). It thus seems that different stressors initiate differential responses, and that the responses depend on the species under study, plus the fatty acid composition of their diet.…”

“…Importance of long-chain polyunsaturated fatty acids (LC-PUFA) such as docosahexaenoic acid (DHA,, eicosapentaenoic acid (EPA, 20:5n-3) and arachidonic acid (ARA, 20:4n-6) is described by several studies in larval fish nutrition (Tocher and Harvie, 1988;Bell et al, 1995;Sargent et al, 1997;Tocher and Ghioni, 1999;Bell et al, 2002;Izquierdo et al, 2005). These LC-PUFA occurance in live prey and early weaning diets plays vital role for nerve system development, growth performance, survival and quality of larvae and juvenile marine fish (Watanabe et al, 1989;Bessonart et al, 1999;Liu et al, 2002;Van Anholt et al, 2004;Ganga et al, 2005;Izquierdo and Koven, 2010;Eryalçın et al, 2013). Because of the limited ability of elongation and desaturation of short chain fatty acids in marine fish, LC-PUFA should be readily presented in their feeds (Sargent et al, 1997;Koven et al, 2001;.…”

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...
