The analytical genetic technologies applicable to aquaculture include: DNA markers, genome mapping, microarrays, and sequencing will come under Fish genetics and fish genome.Humans and fishes share many developmental pathways, organ systems, and physiological mechanisms, making conclusions relevant to human biology. The respective advantages of zebrafish, medaka, Tetraodon, or Takifugu have been well exploited so far with bioinformatics analyses and molecular biology techniques.
