| World aquaculture is growing (+ 8% per year) to meet the increasing demand of fish for human consumption that capture by fisheries can no longer cover. Consequently, the need for aquafeed and feedstuffs is rising while volumes of fishmeal and fish oil, the traditional aquafeed ingredients, remain stable. More and more fishmeal and fish oil are substituted by plant products. Between 80 and 95% of fish meal can be replaced by a combination of plant protein sources providing the indispensable amino acids in sufficient quantity to meet the fish needs. Beyond this substitution rate, feed intake, feed efficiency and growth rate decrease and metabolic changes are observed despite the diets containing all the required nutrients. Fish oil can be replaced by a mix... |

| Our objective was to analyse the hepatic transcriptomes of juvenile rainbow trout fed with a plant-based diet. We focused our analysis on the total replacement of fish meal (FM) and fish oil (FO) by a 100% plant-based diet (0% FM, 0% FO). We analysed the postprandial hepatic transcriptomes of rainbow trout fed the two diets 8 h after feeding. Six total hepatic RNAs from each dietary group were hybridised against a trout cDNA microarray (9K). After treatment of the data respecting the standard MIAME (Minimum Information About a Microarray Experiment) protocol, we found that 176 hepatic genes were differentially expressed between fish fed the two diets: 96 and 80 were over-expressed and under-expressed, respectively, in trout fed the plant-based diet.

| 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... |
