“…Diets containing 8% herring oil significantly altered the fatty acid pattern in favour of (n-3) fatty acids, but there was a tendency to reduction in the sum of (n-3) fatty acids with diets without a-tocopheryl acetate supplementation, compared with diets containing a-tocopheryl acetate (Boggio et al, 1985). Watanabe et al (1977) obtained similar results with carp when methyl-linoleate was added to their food. In a recent experiment, the absence of antioxidants in the diet also reduced the increase in concentration of (n-3) fatty acids in the meat of broiler chickens, given diets containing linseed oil, significantly, compared with the addition of anti-oxidants (Ajuyah et al, 1993).…”

This paper examines the effect of different fatty acid composition, together with varying dietary vitamin E contents on fatty acid composition and tocopherol and tocotrienol contents of carp, and compares with other species of fish and the storage quality of the fish produced. Dietary fatty acid composition affected fatty acid patterns of tissues of carp significantly, but this was correlated with the fat content of the diet. Varying the vitamin E content results in no or only very slight variations in the fatty acid pattern of the tissues. The content of alpha-tocopherol in the tissues was affected significantly by dietary alpha-tocopheryl acetate content and by dietary fat source. There was a negative correlation between (n-3) fatty acids and the storage of alpha-tocopherol, while this was positively correlated with (n-6) fatty acids. The content of alpha-tocopherol in fish affected the stability during storage with the content of malondialdehyde used as a parameter for measuring the extent of fat oxidation. Other relationships, e.g. with sensory qualities and S-containing substances in the edible part of the fish, are discussed.

“…In contrast, dietary α‐Toc exerted no appreciable effects on the lipid content of whole bodies, muscle and hepatopancreas in carp, 30 while an excess dose of α‐Toc increased lipid accumulation in the liver of rainbow trout 31 . It was found that the fatty acid composition of tissues is independent of dietary α‐Toc content once fish have satisfied their minimum requirement 25,30 , 32 . Barja et al 33 .…”

Effect of dietary vitamins C and E fortification on lipid metabolism in red sea bream Pagrus major and black sea bream Acanthopagrus schlegeli

et al. 2003

To determine the effect of vitamins C and E on lipid metabolism and interactions between them, L‐ascorbyl‐2‐monophosphate‐Mg (APM) and α‐tocopherol acetate (TA) were fortified to a commercially based diet and fed to 0‐year red sea bream Pagrus major and 1‐year black sea bream Acanthopagrus schlegeli. Fortification of APM and TA, respectively, increased ascorbate (ASC) and α‐tocopherol (α‐Toc) contents in the organs. In addition, APM fortification increased α‐Toc accumulation in both fishes, although TA fortification did not significantly affect the ASC content. Fortification of APM caused a depression in lipid accumulation in the intraperitoneal fat body and liver in red sea bream. Furthermore, a decrease in the serum thiobarbituric acid value in black sea bream and a reduction of the adipocyte diameter in the APM‐fortified groups of both fishes were observed. However, fortification of TA did not affect these parameters as significantly as did fortification of APM. The shortest recovery time to air‐dipping was found in the APM + TA‐fortified group, followed by the APM‐fortified group in red sea bream. The results implied an effect of vitamin C on lipid metabolism, and acceleration of vitamin E absorption and/or suppression of vitamin E degradation.

“…A dietary requirement for vit. E has been demonstrated in a number of fishes, including a 120 mg kg −1 diet for Atlantic salmon (Hamre and Lie, ), 30–50 mg kg −1 for channel catfish (Wilson et al., ), and 200–300 mg kg −1 for common carp (Watanabe et al., ). An increased dietary PUFA level in the diet causes an increase in the vit.…”

Effects of varying levels of dietary vitamin E (α-tocopherol) on growth performance, proximate and fatty acid composition of juvenile silver pomfret (Pampus argenteus Euphrasen, 1788)

Summary This study investigated the effects of elevated dietary levels of vitamin E (α‐tocopherol) on growth performance, proximate composition and fatty acid profiles of juvenile silver pomfret, Pampus argenteus. Three semi‐purified experimental diets were formulated to contain 49% protein and 16% lipid. High docosahexaenoic acid (DHA) tuna oil was added to the diets to supplement DHA. A graded level of vitamin E (0‐, 50‐, and 100 mg kg−1) was added to experimental diets 1 to 3, respectively. Analyzed vit. E levels were 155.2, 195.3 and 236.4 mg kg−1 in diets 1, 2 and 3, respectively. The experiment was conducted for 12 weeks with juvenile silver pomfret (29.6 ± 7.6 g) using a flow‐through system consisting of nine 1‐m3 tanks. Each treatment had three replicates and fish were stocked at the rate of 20 m−3. Growth performance and feed utilization parameters of fish fed diets 2 and 3 were significantly (P < 0.05) higher than in fish fed diet 1, but the parameters in diets 2 and 3 did not differ significantly (P > 0.05). Although whole body protein levels were not influenced by the dietary vit. E levels, whole body lipid in fish fed diet 2 was significantly higher than in fish fed the other diets. The whole body vit. E levels in fish fed diet 2 (22.6 mg kg−1) and diet 3 (24.1 mg kg−1) were significantly (P < 0.05) higher than in those fed diet 1 (18.2 mg kg−1). Whole body total saturated fatty acids were significantly lower, and DHA levels higher in fish fed diets 2 and 3 than those fed diet 1. The results of the present study suggest that increasing dietary supplementation of vit. E in high lipid diets enhances the growth performance of fish and that a dietary level of 196 mg kg−1 vit. E is suitable for the growth of silver pomfret.
