Aquaculture-oriented genetic researches in abalone: Current status and future perspective

  • Katsutoshi Arai
  • Sei-Ichi Okumura


Basic genetic and cytogenetic information including polymorphic DNA markers, chromosomes and genome size was summarized to get insights into phylogenetic or systematic relationship among abalone species belonging to the genus Haliotis. Hybridization, triploidization and genetic mapping were also briefly reviewed as aquaculture-oriented genetic techniques to improve growth and other commercially important traits. Cryopreservation and other biotechnologies potentially applicable on genetic improvement were also briefly mentioned as supporting tools for efficient breeding of abalone strains.

Keywords: Chromosome, DNA markers, genetic map, genome size, Haliotis, hybrid, polyploidy, selection
