Over the past decade, sustainable aquaculture production promoting increasing dietary replacement of fisheries by plant ingredients has steadily grown, often reducing the palatability of fish diets and animal performance. However, very little information exists on taste-related mechanisms possibly underlying these effects. Vertebrate taste perception is largely controlled by two families…
A feeding trial was conducted to test the application of a Functional Palatability Enhancer (FPE) containing umami compounds in improving the feed palatability and performance of Snakehead fish fed low-fishmeal diets. Seven isonitrogenous (43% crude protein) and isolipidic (7% total lipid) test diets were formulated, where diet 1 was a…
Feed additives including flavours and umami compounds could be beneficial for improving palatability and functionality of fish diets, especially when dietary fishmeal is replaced by plant-based protein sources. Aimed to apply the proposed new strategy in shrimp production, the present study was designed to test the effect of supplementation of…
To assess the hypothesis of central amino acid-sensing systems involved in the control of food intake in fish, we carried out two experiments in rainbow trout. In the first one, we injected intracerebroventricularly two different branched-chain amino acids (BCAAs), leucine and valine, and assessed food intake up to 48 h…
TOP CITED PAPERS IN REVIEWS IN FISHERIES SCIENCE AND AQUACULTURE 2019 Recent advances in understanding the molecular basis of taste physiology in fish could open new opportunities to optimize feeding performance in aquaculture. This is particularly relevant at a time when alternative ingredients are being increasingly used, often reducing the…
Trans-intestinal absorption (TIA) rates for the free amino acids (FAA) alanine, proline, and glutamic acid were measured in two developmental phases of Atlantic herring larvae: Early(14–16 day-post-hatch) and Late (37–39 day-post-hatch). TIA rates were determined by measuring net uptake of a 14C-radiolabeled FAA tracer solution into the body after administration…
