“…It was showed that there were significantly higher lipid contents in the whole body and hepatopancreas of juvenile O. macrolepis fed on the experimental diets with a dietary lipid content of 11.95% or higher. In most species, such as common carp ( Cyprinus carpio ; Sabzi, Mohammadiazarm, & Salati, ), Argyrosomus regius (Antonopoulou, Kousidou, Tserga, Feidantsis, & Chatzifotis, ), giant croaker ( Nibea japonica ; Han et al, ), spinefoot rabbitfish ( Siganus rivulatus ; Ghanawi, Roy, Davis, & Saoud, ), Pelteobagrus vachelli (Zheng et al, ), tiger puffer ( Takifugu rubripes ; Kikuchi, Furuta, Iwata, Onuki, & Noguchi, ) and white seabass, Atractoscion nobilis (López, Durazo, Viana, Drawbridge, & Bureau, ), excessive dietary lipid supplies not only do not promote growth, but also can lead to unnecessary lipid deposition in hepatopancreas or other tissues. This is waste of energy, as it is inefficient to supply nutrients if they are essentially not used.…”

Five diets of different lipid levels, 3%, 6%, 9%, 12% and 15% (L3, L6, L9, L12 and L15), were designed and fed to juvenile Onychostoma macrolepis for 8 weeks. The juvenile O. macrolepis grew better at L9 than at L3, L6 and L15 (p < .05). The viscera and hepatopancreas indexes increased as the dietary lipid levels increased. There appeared lower serum TG and HDL levels at lipid levels of 3.01%–9.01% (p < .05). Hepatic histology showed that the fish fed on L15 diet had more hepatic lipid droplets than those fed on the other diets. Fish fed on L9 diet showed increases in superoxide dismutase, catalase and glutathione peroxidase activities but decreases in malondialdehyde content in hepatopancreas (p < .05). The principle component analysis of fatty acid showed that n‐3 LC‐PUFA was mostly enriched in the fillet. There were lower transcript levels of FAS, ACC1 and SREBP1 found in the hepatopancreas of fish with increased dietary lipid levels, whereas CPT‐1, PPARα and ATGL expressions were elevated (p < .05). These results suggested that diets with a proper dietary lipid level of 9.01%–11.95% (optimum 9.68% was based on the specific growth rate) could improve the growth performance and health status of juvenile O. macrolepis.

“…Plus, protein sparing effects induced by the increase in dietary lipids have been documented in many fish species (Torstensen et al 2001;Chatzifotis et al 2010;Karalazos et al 2011), which was beneficial for growth performance and maximized the nitrogen retention (Cho and Kaushik 1990). Dietary lipid levels have been found in numerous reports to affect fish health status (Chatzifotis et al 2010;Jin et al 2013;Zhang et al 2013;Antonopoulou et al 2014). Further, dietary lipid sources and essential FAs are the most important factors for fish immune response and disease resistance (Turchini et al 2003;Subhadra et al 2006;Jobling et al 2008).…”

The present study aimed at determining the growth performance, feed utilization, body composition and antioxidant status of chu's croaker (Nibea coibor) juveniles fed with increasing levels of dietary lipid: 6 % (D6), 9 % (D9), 12 % (D12) and 15 % (D15). Each diet was assigned to triplicate groups of fish in a total of 12 floating pens (300 fish, 25 fish per pen). After a 49-day growth trial, survival rate was not affected. D12 and D15 led to significantly higher specific growth rate (SGR). Fish fed D12 showed the highest protein efficiency ratio (PER), protein and lipid retention efficiencies (PER and LRE, respectively). The hepatosomatic and viscerosomatic indexes (HIS and VSI, respectively) increased, while feed conversion ratio (FCR) and feed intake (FI) decreased. Body protein, ash and muscle lipid contents were not significantly affected, but significantly higher body and liver lipid were noticed in fish fed with D15. Monounsaturated fatty acid (MUFA) was found to decrease compared to the experimental diets in muscle, while high unsaturated fatty acid (HUFA) was selectively accumulated in all treatments. Serum alanine transaminase (ALT, 14.13-22.53 U/L), aspartate transaminase (AST, 34.31-51.25 U/L), cholesterol (CHO, 2.02-3.03 mmol/L) and triglyceride (TG, 5.61-8.50 mmol/L) were correlated with increasing dietary lipids. Liver malate dehydrogenase (MDA, 3.32-6.67 mmol/L) and superoxide dismutase (SOD, 42.69-52.86 U/mg prot) increased with dietary lipids, while total antioxidant capacity (t-AOC, 1.08-3.50 U/mg prot) decreased. Polynomial regression analyses between SGR and dietary lipid levels showed that the optimal dietary lipid requirement of chu's croaker is 12.9 % of dry matter.

To investigate the effect of dietary lipid levels on lipid metabolism in muscle and adipose tissue of large yellow croaker (Larimichthys crocea), fish (average body weight 150.0 g) were fed to one of three diets with a low (6%), moderate (12%, the control diet) or high (18%) crude lipid level for 10 weeks. The expression of genes related to lipoprotein clearance (lpl, ldlr, lrp1 and srbi), fatty acid transport (cd36, fatp1, fabp3 and fabp11), lipogenesis (fas and dgat2) and lipolysis (atgl, cpt1 and aco) in muscle and adipose tissue was analysed. In muscle of fish fed the low‐lipid diet, the expression of lpl, lrp1, fas, dgat2 and atgl was significantly downregulated, whereas fabp3 and fabp11 were significantly upregulated compared with those fed the control diet. In muscle of fish fed the high‐lipid diet, the expression of lpl, ldlr, lrp1, cd36, fabp3, fas and dgat2 was significantly decreased, while fabp11 expression was significantly increased compared with those fed the control diet. Compared with the control group, only a significant downregulation of fabp3 expression in adipose tissue was observed in the low‐lipid group. In the high‐lipid group compared with the control group, the expression of ldlr, fabp11, dgat2, atgl and aco in adipose tissue was significantly upregulated, whereas cpt1 expression in adipose tissue was significantly downregulated. These results indicated that the expression of the selected key genes related to lipid metabolism was tissue‐specific regulation by dietary lipid levels in large yellow croaker.
