“…Based on the strength of the second-order polynomial regression analysis of WGR and FCR, the requirement of dietary lipids for large-sized common carp with an IBW of 247.00 ± 16.67 g was estimated to be 59.5-70.4 g/kg. This requirement is 10-30 g/kg lower than that observed in common carp with an IBW of 5.51 ± 0.05 g (24), common carp with an IBW of 15 g (26), and common carp with an IBW of 36.12 ± 1.18 g (5). The above difference supports somehow the hypothesis that there is a more excellent nutritional requirement in the juvenile stage.…”

“…For decades, the exploration of an approach to minimizing the dietary protein consumption and simultaneously maximizing the protein utilization efficiency has been extremely imperative for the sustainable development of the aquaculture feed industry (1)(2)(3). Investigators have begun to perform feasibility studies on the protein-sparing effect of lipids in fish diets (4)(5)(6)(7). In addition to the prominent protein-sparing effect, the traditional functions of lipids involve the provision of high energy values, promotion of the absorption of fat-soluble vitamins, inhibition of dust, improvement of the palatability, etc., which are important for the feed industry (8).…”

An 82-day study was conducted to assess the effect of the dietary lipid levels on growth performance, feed utilization, lipid deposition, and hepatopancreas lipometabolism of large-sized common carp (Cyprinus carpio). Six isonitrogenous (300 g/kg protein) pelletized diets with different dietary lipid levels (30, 60, 90, 120, 150, and 180 g/kg) were fed in triplicate to fish groups with 75 individuals (with an initial mean weight of 247.00 ± 16.67 g). The results showed that there was a significant increase in weight gain (WG) rate (WGR), specific growth rate (SGR), and protein efficiency ratio (PER) as dietary lipid levels increased from 30 to 60 g/kg (p < 0.05) and then there was a decline. Feed conversion rate (FCR) was observed to be significantly lower in 60 g/kg lipid treatments (p < 0.05). Muscle crude protein contents were obtained to be significantly higher in 60 and 90 g/kg treatments (p < 0.05). The crude lipid content in the hepatopancreas increased significantly with an increase in dietary lipid levels (p < 0.05). The expression of lipoprotein lipase (LPL) and carnitine palmitoyltransferase-1 (CPT1) in the hepatopancreas was significantly downregulated with an increase in dietary lipid levels while the expression of growth hormone (GH), insulin-like growth factor-1 (IGF-1), fatty acid synthase (FAS), acetyl-CoA carboxylase-1 (ACC-1), and sterol regulatory element binding protein (SREBP) was upregulated first in 30 and 60 g/kg lipid treatments and then downregulated significantly in other treatments. The results revealed that excess dietary lipid supplements (more than 60 g/kg) would inhibit WG and would aggravate the lipid decomposition in the hepatopancreas. Based on WGR and FCR, the dietary lipid levels of 59.5 and 70.4 g/kg were optimal for growth performance and feed utilization of large-sized common carp.

“…Fish oil and soybean oil were added equally as lipid sources. Optimal lipid dietary level suggested for common carp is around 60 g/kg (Fan et al, 2015;Manjappa & Keshavanath, 2002). Therefore, high dietary lipid (90 g/kg) level used in this study was supported by Taneja and Arya (1994).…”

We aimed to investigate the effect of xylooligosaccharides (XOS) on the growth performances and lipid metabolism of common carp fed high‐fat diets. 192 fish were randomly distributed into 24 tanks into six groups (four replicates) and were fed with control diet, high‐fat diet (HFD) and HFD supplemented with 5, 10, 20 and 30 g/kgXOS respectively for 8 weeks. Fish fed HFD supplemented with 10 g/kg XOS obtained higher final body weight, weight gain, specific growth rate and protein efficiency ratio compared to those fed control diet and HFD, while feed conversion ratio showed the opposite trend. Fish fed HFD obtained higher hepatosomatic index, abdominal fat, energy intake compared to other groups, whereas the opposite was true for nitrogen retention. High plasma levels of cholesterol, triglycerides, low‐density lipoprotein and low high‐density lipoprotein were observed in fish fed HFD; opposite was true for fish fed HFD supplemented with 10–20 g/kg XOS. The transcription of lipoprotein lipase was up‐regulated, whereas that of carnitine palmitoyltransferase I, peroxisome proliferator‐activated receptors alpha, acyl‐CoA oxidase and CD36 were down‐regulated in fish fed HFD. Opposite trend was observed in fish fed HFD supplemented with 10–20 g/kg XOS as well as the control group. In conclusion, XOS inclusion can benefit the growth performance and lipid metabolism of common carp fed HFD.

“…However, a dietary lipid increases toward an upper limit often lead to unwanted deposition in the liver (or other tissues), inducing a condition referred to as fatty liver thereby reducing growth performance (Du et al, ; Gaylord & Iii, ; Lu et al, ). For example, common carp ( Cyprinus carpio ) fed a high‐fat diet (containing 90g/kg lipid) exhibited reduced growth performance and upregulated LPL expression (Abasubong et al, ; Fan et al, ). Also, high‐fat intake (100 or 150g/kg fat level) leads to excessive fat deposition in the liver of blunt snout bream ( Megalobrama amblycephala ) coupled with a decreased growth performance and increased TG and TC (Chen et al, ; Li et al, ; Lu et al, ).…”

This study established the effects of betaine and choline association on lipid metabolism of blunt snout bream (Megalobrama amblycephala) fed high-fat diet (HFD).Fish (43.73 ± 0.13 g) were randomly distributed into 21 cages in seven groups (three replicates) and fed with control diet, HFD and HFD+ betaine and choline associated at different levels (16, 12, 8, 4 or 0 g/kg betaine and 0, 2, 4, 6 or 8 g/kg choline), designated as diet 1, diet 2, diet 3, diet 4, diet 5, diet 6 and diet 7 respectively for 8 weeks. Fish fed diet 4 obtained higher final body weight, weight gain and specific growth rate whereas feed conversion ratio showed the opposite trend compared to those fed HFD. Higher plasma levels of cholesterol, triglycerides, low-density lipoprotein tHcy and low levels of high-density lipoprotein, S-adenosylmethionine, S-adenosylhomocysteine were observed in fish fed HFD; the opposite was true for fish fed diet 4. Also, a lower liver superoxide dismutase, glutathione peroxidase activities and a higher malondialdehyde content were observed in fish fed HFD. This effect was reversed with fish fed diet 4. The transcription of Betaine-homocysteine S-methyl-transferase1, glycine N-methyltransferase and monoacylglycerol O-acyltransferase 1 were upregulated in fish fed HFD. The opposite trend was observed in fish fed diet 4. In conclusion, betaine and choline associated diets can benefit growth and lipid metabolism of blunt snout bream fed HFD.
