Effects of dietary <i>α</i>‐linolenic acid/linoleic acid ratio on growth performance, tissue fatty acid profile, serum metabolites and <i>Δ6 fad</i> and <i>elovl5</i> gene expression in silver barb (<i>Puntius gonionotus</i>)

Abstract

Silver barb possess the ability to elongate and desaturate ALA and LA to their end products EPA and DHA. The highest level expression of Δ6 fad and elovl5 mRNA at the dietary ALA:LA ratio of 2.66 suggests greater affinity of these enzymes towards ALA than LA in silver barb. © 2019 Society of Chemical Industry.
