The tropical gar (Atractosteus tropicus) is an economically and socially important freshwater fish species from southeastern Mexico, with high aquaculture potential. This study determined the expression of acetyl-CoA carboxylase (ACC1), fatty acid synthase (FAS), carnitine palmitoyl transferase 1 (CPT1C) in several tissues adult specimens, as well early ontogeny stages gar. Partial sequences all genes were obtained for brain, liver, muscle, mesenteric adipose, kidney, testis, gill, heart males. Specific qPCR primers used to compare between also during larviculture, starting embryos (0 days after hatching, [DAH]), at 5, 10, 15, 20, 25, 30 DAH. Mesenteric adipose tissue, muscle showed maximum FAS, ACC1, CPT1C expression. Additionally, highest lipogenic was detected DAH), decreasing 5 10 DAH, then increasing 15 ultimately again 20 DAH onwards. Based on these results, it can be concluded that encoding are expressed differentially across adults, regulated larval development.
