General Information

General Information Comment Organism
metabolism in mollusks, anaerobic conditions, in addition to the lactate dehydrogenase (LDH) activity, have been shown to produce energy by the arginine phosphate/arginine kinase system in which octopine dehydrogenase (ODH) is involved. ODH maintains a lower cytosolic redox ratio (NADH/NAD+) than LDH during anoxia, where the glycolytic pathway is prevalent. Activity of key enzymes of intermediary metabolism in Octopus vulgaris palarvae at hatching and after 12 and 28 days of feeding with control diet (Artemia enriched with phytoplankton) or LC60 diet (Artemia enriched with marine lecithin), overview Octopus vulgaris
physiological function analysis of the metabolic organization of octopus paralarvae throughout an ontogenic period of 12 days post-hatching, as well as assessment of the effect of diet enrichment with live prey containing abundant marine phospholipids. Throughout the ontogenic period studied, an increase in anaerobic metabolism takes place largely due to an increased dependence of paralarvae on exogenous food. This activity is supported by octopine dehydrogenase activity, with a less significant contribution of lactate dehydrogenase activity. Regarding aerobic metabolism, the use of amino acids is maintained for the duration of the experiment, and a significant increase in the rate of oxidation of fatty acids from 6 days after-hatching is observed. Capacity for de novo synthesis of glucose from amino acids and glycerol is also observed. Feeding larvae with phospholipid-enriched Artemia improves animal viability and welfare, significantly increasing the rate of survival and growth of paralarvae Octopus vulgaris
