Hatchery-reared juvenile black sea breams are characterized by a low level of highly unsaturated fatty acids in their bodies, as compared with wild fish. To assess the effect of docosahaxaenoic acid (DHA) on lipogenic and lipolysis enzymes, one-year fish were reared on a casein-based purified diet and a DHA fortified diet (1.5% DHA ethyl ester/kg diet) for 60 d, followed with a period of 55 d for starvation. Dietary DHA was effectively incorporated into the fish body. Fortification of DHA… 

Adaptation of AMPK-mTOR-signal pathways and lipid metabolism in response to low- and high-level rapeseed meal diet in Chinese perch (Siniperca chuatsi)

It is suggested that both RSL and RSH diets decreased lipid accumulation in Chinese perch; however, the mechanism of lipid metabolism was different and the lipid accumulation was decreased in the liver.

Effects of dietary n-3HUFA on juvenile white shrimp, Litopenaeus vannamei: Growth, feed utilization, antioxidant enzymes activities and fatty acid compositions

The effects of n‐3 high‐unsaturated fatty acid (n‐3HUFA) levels on growth performance, antioxidant enzymes activities and fatty acid compositions of juvenile Litopenaeus vannamei are investigated.

Cytochrome P450 2AA molecular clone, expression pattern, and different regulation by fish oil and lard oil in diets of grass carp (Ctenopharyngodon idella)

This study cloned the complete CDS of the cytochrome P450 2AA (CYP2AA) gene from the grass carp for the first time, provided molecular characterization and expression profile of CYP2AA, and enhanced the understanding of CYp2AA in fish lipid metabolism.

Regulation of adipocytes lipolysis by n-3 HUFA in grass carp (Ctenopharyngodon idellus) in vitro and in vivo

Novel evidence is provided that n-3 HUFAs could regulate grass carp adipocytelipolysis in vitro or in vivo, and the effect might be in part associated with their influence on the expression of lipolysis-related genes and lipolysin-related adipokines genes.



Dietary effects of eicosapentaenoic acid and docosahexaenoic acid on lipid metabolism in black sea bream

The present results implied conversion of EPA to DHA in the fish with regard to parameters, such as lipid metabolism and physiological vitality, which were confirmed in 0-year black sea bream Acanthopagrus schlegeli.

Effect of dietary ascorbate fortification on lipolysis activity of juvenile black sea bream Acanthopagrus schlegeli

Although APM fortification did not influence growth, survival or fish body composition, adipocyte diameter in the intraperitoneal fat body (IPF) was significantly reduced and the results suggested the necessity of fortification with an adequate amount of ascorbate in the diet.

Alteration of liver and muscle fatty acid composition in gilthead seabream (Sparus aurata) juveniles held at high stocking density and fed an essential fatty acid deficient diet

High stocking density in fish fed the EFA deficient diet induced a higher degree of EFA deficiency symptoms leading to mortality, liver steatosis, liver lipid deposition, reduced muscle lipid and reduced n-3 HUFA contents, which particularly affected EPA, but not DHA, suggesting a preferential retention of the latter fatty acid, specially in the phosphoglycerides fraction.

Effects of varying dietary fatty acid profile on growth performance, fatty acid, body and tissue composition of juvenile pike perch (Sander lucioperca)

Liver tissues of fish fed diets enriched with vegetable oils showed significantly increased lipid contents of 162 (LO) and 147 (SO) gkg-1 and indicate decreased lipid utilization compared with fish fed FO diet (liver lipid content 112 g kg-1).

The hypotriglyceridemic effect of dietary n−3 FA is associated with increased β-oxidation and reduced leptin expression

The results indicate that the hypotriglyceridemic effect of dietary n−3 PUFA is associated with stimulation of FA oxidation in the liver and to a smaller extent in skeletal muscle, and may ameliorate dyslipidemia, tissue lipid accumulation, and insulin action in spite of decreased plasma leptin level and leptin mRNA in adipose tissue.

Abdominal fat deposition and fatty acid synthesis are lower and beta-oxidation is higher in broiler chickens fed diets containing unsaturated rather than saturated fat.

The lower fat deposition observed in broilers fed sunflower oil-enriched diets appears to be the net result of an increased rate of lipid catabolism and lower rate of fatty acid synthesis despite higher dietary fat absorption.

Further studies on the properties and assay of glucose 6-phosphate dehydrogenase and 6-phosphogluconate dehydrogenase of rat liver.

The significance of this pathway in animal tissues, its physiological control and the relative importance of the direct oxidative and glycolytic routes of carbohydrate metabolism are still, however, chiefly matters of conjecture.

A rapid method of total lipid extraction and purification.

The lipid decomposition studies in frozen fish have led to the development of a simple and rapid method for the extraction and purification of lipids from biological materials that has been applied to fish muscle and may easily be adapted to use with other tissues.
