  2. 2. Higher feed cost Higher water pollution Better carbohydrates utilization will increase protein sparing hence it will present economical and environmental advantagesOK !
  3. 3. The graphics show:a. Blood glucose higher in carnivorous than herbivorous fishesb. Plasma insulin higher in carnivorous than herbivorous fishesc. Phosphofructokinase higher in herbivorous than carnivorous fishes
  4. 4. Plasma glucose decrease below 100 mg/dlonly after 8 hours in carnivorous fish.

Species Carbohydrates digestion Glucose utilisation Less ability but prefer to low amylopectin-containedAsian seabass (Lates calcarifer) Poor (4) and gelatinized starch (1–3)Atlantic halibut (Hippoglossus Less active amylase (5) Poor, but 5%-8% better than 2% (5)hippoglossus) Poor, but prefer to low level (<16%) (6) &Atlantic salmon (Salmo salar) Less active amylase (6) higher temperature (180C) (7) Digest gelatinized starch up to 80% for <24,2% in feedCobia (Rachycentron canadum) Low utilized (9) (8)European seabass (Dicentrachus Less amylolytic activity, suggested concentration <30% Poor (prolonged hyperglycemia) (10)labrax) in diet (10) Better amylolitic activity, better digest wheat andGilthead seabream (Sparus aurata) Restore plasma glucose after 12 h (14) extruded source (11–13) Prefer starch than glucose (E. malabaricus, E. coioides) Protein sparing at low protein diet (E.Grouper (15, 16) malabaricus) (17)Japanese flounder (Paralichthyis Utilize dextrin better than cellulose, maltose, glucoseolivaceus) Hyperglycemia 16-24 h (18) (18)Rainbow trout (Onchorynchus Low digestible (19–21) Poor (22–25)mykiss)Red drum (Sciaenops ocellatus) Low digestible but prefer complex starch (26) Low utilized (26)Red seabream (Pagrus major) Low digestible (27, 28) Low utilized compared to lipid (29, 30)Southern bluefin tuna (Thunnus Assumed to be low digestible because low amylase -maccoyii) present (31–33) Low digestible but prefer complex starch (10%-20% Low restore because low plasma insulinYellowtail (Seriola quinquerradiata) diet) (34, 35) level (35)
  6. 6. Low concentration digestive enzymes (Helland and Helland, 2002)Short gut intestine (Drew et al 2004)Glucose low stimulate insulin secretion (Mommsen et al, 1991)The relatively low number of insulin receptors in fish muscle as compared to the rat(Pa´rrizas et al. 1994)Low number of glucose transporters in fish muscle (Wright et al. 1998)A low glucose phosphorylation capacity (Cowey and Walton 1989)An imbalance between hepatic glucose uptake and endogenous production(Panserat et al. 2001a)
  7. 7. Explanation for low glucose utilization by Enes et al (2009)1. Data strongly suggest that the liver of most fish species is apparently capable of regulating glucose storage2. However, endogenous glucose production is still high whether fish is in feeding or fasting state.3. This endogenous glucose production leads a putative competition with exogenous (dietary) glucose.4. This may explain the poor glucose utilization in fish (Enes et al. 2009)But why is endogenous glucose production highly persistent ?New explanation may be found here:1. Gluconeogenesis could be induced by fatty acid oxidation (Randle, 1988)2. Fatty acid oxidation could be induced by PUFA rich diet (Clarke, 2001)
  8. 8. Utilization of fatty acid as energy source Utilization of glucose as energy sourceprevent glucose utilization prevent triacyl glycerol breakdown
  9. 9. Fatty acids that have two or more double bondslinoleic acid (LA)γ-linolenic acid (GLA)arachidonic acid (AA)Alpha-linolenic acid (ALA)Eicosapentaenoic acid (EPA)Docosahexaenoic acid (DHA)
  10. 10. (Delarue et al., 2004; Ghafoorunissa et al., 2005; Postic et al., 2007; Fedor and Kelley, 2009;González-Périz et al., 2009) PUFA Can not cure insulin resistance Its only Prevent insulin resistance by reduce lipid deposition 1. Decrease lipogenesis and glicolysis 2. Increase lipolysis and beta oxidation and gluconeogenesis
  11. 11. Induce fatty acid oxidationlipolysisglycogenesisglucogenesisInhibitlipogenesisglycolysisBy governingDNA binding activityand nuclear receptors
  13. 13. 1. Reducing the nuclear abundance and DNA-binding affinity of transcription factors responsible for imparting insulin and carbohydrate control to lipogenic and glycolytic genes.2. In particular, PUFA suppress the nuclear abundance and expression of sterol regulatory element binding protein-1 and reduce the DNA-binding activities of nuclear factor Y, Sp1 and possibly hepatic nuclear factor-4
  14. 14. The higher rates of fatty acid oxidation observed in humans and animals fed dietsrich in PUFA (Clark, 2001)Oxidation of fatty acids and ketone bodies inhibit glucose metabolism in cardiacand red skeletal muscle and induce gluconeogenesis (Randle, 1988)Utilizing lipid simultaneously as energy source impairs insulin response by glucose(Randle, 1998)Fish prolonged uptake PUFA, hence simultaneously use to fatty acid asrespiratory substrates, induce gluconeogenesis finally impairs insulinresponse and may have implication in metabolic inflexibility.
  15. 15. Metabolic inflexibility is simultaneously influenced by environmental condition Carbohydrates-rich food chain Lipid-rich food chain Glucose Lipid Glycolisis Beta oxidation Glycogenesis Lipogenesis Gluconeogenesis Natural programming
  16. 16. Nutritional programming1. Specific fish habitat provide particular feeds that may naturally contain specific food composition. They consume these kinds of feeds continuously.2. Fish adapt efficiently to this condition by performing certain metabolic pathway more often than the others. It means some genes express more frequent than the others. Afterward , this state become fish habit.3. It could be changed by early programming of larvae. They are conditioned simultaneously by particular set of nutritional state that induce desired gene expression relates to specific metabolic pathway.4. Consequently this metabolic state is still continued in the latter of fish live stage.
  17. 17. Nutritional Programming for glucose utilization (Geurden et al 2007)Based on the concept of nutritional programming in higher vertebrates, it was tested whether an acute hyperglucidicstimulus during early life could induce a long-lasting effect on carbohydrate utilization in carnivorous rainbow trout.1. hyperglucidic diet (60% dextrin) at two early stages of development: either at first feeding (3 days, stimulus 1) or after yolk absorption (5 days, stimulus 2).2. Before and after the hyperglucidic stimulus, they received a commercial diet until juvenile stage (>10 g).3. Fish that did not experience the hyperglucidic stimuli served as controls.4. The short- and long-term effects of the stimuli were evaluated by measuring the expression of five key genes involved in carbohydrate utilization: α-amylase, maltase (digestion), sodium-dependent glucose cotransporter (SGLT1; intestinal glucose transport), and glucokinase and glucose-6-phosphatase, involved in the utilization and production of glucose, respectively.5. The hyperglucidic diet rapidly increased expressions of maltase, α-amylase, and glucokinase in stimulus 1 fish and only of maltase in stimulus 2 fish, probably because of a lower plasticity at this later stage of development.6. In the final challenge test with juveniles fed a 25% dextrin diet, both digestive enzymes were upregulated in fish that had experienced the hyperglucidic stimulus at first feeding, confirming the possibility of modification of some long-term physiological functions in rainbow trout.7. In contrast, no persistent molecular adaptations were found for the genes involved in glucose transport or metabolism. In addition, growth and postprandial glycemia were unaffected by the stimuli.8. In summary, data show that a short hyperglucidic stimulus during early trout life may permanently influence carbohydrate digestion.
  18. 18. Conclusion1. Many evidences show that fishes utilize carbohydrates and glucose poorly2. Carnivorous fishes are lower utilize carbohydrates than the herbivorous3. Several hypothesis that explain the phenomenon still raise many questions4. Randle’s cycle explain more clearly that glucose utilization is inhibited by fatty acid utilization.5. Inhibition of glucose utilization much more plainly by glicolysis inhibition by PUFA6. In certain level, glucose utilization capability in fish could be increased by early programming7. Conclusion
