“…In our study, the VSI, BFR, and MSI in fish fed with low and high levels of rapeseed meal diets decreased compared to the control group, while no significant difference was found in HSI. Similar results were found in gilthead sea bream (Gomez-Requeni et al 2004), and Salminus brasiliensis (Correa et al 2020). The results further proved that the replacement of rapeseed meal could decrease fat deposition in viscera rather than the liver.…”

It is well known that carnivorous fish cannot use plant-proteins efficiently. They affect lipid metabolism of fish and cause serious problems to fish health. The reasons for this deficiency of fish metabolism are not known well. Chinese perch, a carnivorous fish, can accept artificial diet after domestication and is also considered as a novel model of fish for nutrition studies. Therefore, the aim of this study was to explore the effect of fish meal replacement by low-or high-rapeseed meal on lipid and glucose metabolism of Chinese perch. Three experimental diets were formulated with 0, 10%, and 30% rapeseed meal, named as Control, RSL, and RSH groups, respectively. After 8-weeks of the feeding trial, the inhibition of growth and fat deposition were observed in Chinese perch fed with rapeseed meal diets compared to the control group. Fish fed with RSL diets showed decreased food intake, serum low density lipoprotein (LDL), phosphorylated Grb10 (P < 0.05), inhibited fatty acid (FA) transport (lipoprotein lipase (LPL)), and glycerol synthesis (phosphoenol pyruvate carboxykinase (PEPCK)) in the liver. In addition, fish fed with RSL diets were also inhibited FA synthesis (fatty acid synthase (FAS), sterol regulatory element binding protein 1 (SREBP1), and Acetyl-CoA carboxylase (ACC1)), lipid uptake (hepatic lipase (HL)), β-oxidation (carnitine palmitoyltransferase I (CPT1)), and glycerol synthesis (PEPCK) in the visceral adipose tissue. Fish fed with RSH diets showed phosphorylated AMPK, inhibited FA synthesis (SREBP1, ACC1, and FAS), while enhanced lipolysis (hormone-sensitive lipase (HSL)), and then reduced Acetyl-CoA pool. In turn, β-oxidation (peroxisome proliferator-activated receptor-a (PPARα) and CPT1) was inhibited, while glycolysis (glucose-6-phosphatase (G6PD) and pyruvate carboxylase (PC)) were enhanced, consequently the lipid accumulation was decreased in the liver. Fish were also inhibited lipid uptake (LPL), that caused inhibiting of FA synthesis (SREBP1), β-oxidation (CPT1), glycerol synthesis (PEPCK), and in turn improved lipolysis (HSL) in the visceral adipose tissue. Our study suggested that both RSL and RSH diets decreased lipid accumulation in Chinese perch; however, the mechanism of lipid metabolism was different. Fish accepted less diet in RSL group, which inhibited lipid metabolism in the liver and in the visceral adipose tissues, while fish in RSH group activated AMPK pathway, inhibited FA synthesis, and enhanced lipolysis, which reduced Acetyl-CoA pool in the liver. Subsequently, lipid uptake and metabolism were inhibited in the visceral adipose tissue of RSH fish.

Background: Chinese perch, a carnivorous fish, can accept artificial diet after domestication nowadays, and this farm way will gain high economic interest and sustainability. However, the high content and high quality requirement of dietary protein make it need the high cost in Chinese perch. Therefore, the aim of this study was to explore the effect of fish meal replacement by low- or high-rapeseed meal on growth performance, feeding, lipid and glucose metabolism. Methods: Three experimental diets were formulated with 0, 10% and 30% rapeseed meal, named as control, RSL and RSH, groups respectively. After the 8-week of feeding trial, growth performance, lipid metabolism and AMPK-mTOR-signal pathways were measured. Results: Chinese perch fed with RSH and RSL diets showed significantly decreased WG, SGR, BFR, VSI, MSI and the whole-body crude lipid compared to those fed with the control diet (P < 0.05). Fish in RSL group decreased feed intake, serum LDL-C, hepatic mRNA expression of LPL, PEPCK and phosphorylated Grb10 (P < 0.05). In visceral adipose tissue, mRNA expression of FAS, SREBP1, ACC1, HL, CPT1 and PEPCK were all significantly down-regulated (P < 0.05). Fish in RSH group showed phosphorylated AMPK, hepatic mRNA expression of SREBP1, ACC1, FAS, PPARα and CPT1 were down-regulated, while HSL, G6PD and PC were up-regulated (P < 0.05). In visceral adipose tissue, mRNA expressions of SREBP1, LPL, CPT1 and PEPCK were down-regulated, while mRNA expression of HSL was up-regulated (P < 0.05). Conclusions: Chinese perch fed with RSL and RSH diets showed decreased fat deposition in viscera. Fish fed with low level of rapeseed meal diet ate less diet, which caused inhibited lipid metabolism in the liver and visceral adipose tissues.Fish fed with high level of rapeseed meal diet inhibited hepatic FA synthesis, activated lipolysis, hence reducing Acetyl-CoA pool. In turn, β-oxidation were inhibited, glycolysis was activated, thus lipid accumulation was decreased. In visceral adipose tissue, lipid uptake was inhibited, caused inhibited FA synthesis, β-oxidation, glycerol synthesis, and improved lipolysis.
