| Optimizing the metabolic use of these carbohydrate-rich plant products in fish feeds could be achieved through nutritional programming strategies of fish larvae. The present study aims at testing the long-term effect of an early-life high-carbohydrate nutritional (34% of starch in the feed) stimulus in European sea bass (Dicentrarchus labrax), by examining several biochemical and molecular parameters involved in carbohydrate metabolism in sea bass larvae and juveniles, compared to a control group fed standard larval regime (phase 1). As awaited, specific activities of digestive enzymes, from pancreatic and intestinal segments, involved in glucide digestion (amylase, sucrase) were enhanced together with an up-regulation of glucokinase gene and... |

| Formaldehyde was used to disinfect Artemia cysts and nauplii, while introducing two probiotics in the enrichment process: Bactocell (Pediococcus acidilactici) and Levucell (Saccharomyces cerevisiae). The disinfectant was selected due to its potential compatibility with probiotics, since it was more effective against Gram-negative bacteria than against lactic acid bacteria and yeast. However, the presence of formaldehyde reduced the intake of P. acidilactici in Artemia. Consequently, the disinfection was stopped before Bactocell supplementation to the nauplii fed to pollack (Pollachius pollachius) larvae. The mean weight of pollack was higher with this probiotic treatment. Growth was even better with the combination of Levucell and Bactocell, but the yeast... |
