    Cold-shock androgenesis in common carp (Cyprinus carpio)

  • Original language description

    Methods of induction of uniparental inheritance have been developed for model organisms as well as for species of commercial interest to fix sex-specific traits in breeding programs or to restore breeds or lines from cry-opreserved sperm in aquaculture important species. Androgenesis in common carp (Cyprinus carpio) has been successfully induced by egg nucleus inactivation with gamma-, X-or UV-ray irradiation but these techniques are not widely applicable for laboratory or commercial use on practical, financial and safety grounds. In the past decade a promising low-cost, low-tech cold-shock approach for successfully inducing androgenesis has been demonstrated for loach, Japanese flounder and zebrafish. The aim of the current study was to develop a cold shock methodology for application in common carp, a freshwater species of high commercial interest and a widely used model species. Gametes were collected from wild-type females (dominant green phenotype) and Koi males (recessive blonde phenotype) to enable easy identification of successful induction of androgenetic haploid progeny. A combination of different temperature treatments (0, 2, 4, 6, 8 degrees C) and different cold-shock durations (15, 30, 45, 60, 75 min) applied shortly after gamete activation (3 s after fertilization) were initially trialed. Optimal condition for egg nucleus elimination was a cold-shock at 2 degrees C for 60 min duration where hatching rate of haploid progeny reached 35.6% and 26.26 +/- 10.19% across two attempts. Double haploid induction was then attempted with three replicates (300 g egg) with following parameters 2 degrees C cold-shock for 60 min, then transferred into 20 degrees C and subsequently treated by a heat shock arresting first mitotic cleavage applied 40 min at 40 degrees C for 2 min. These combined treatments resulted in reduced fertilization and hatching rates for all replicates and low yield of progeny (1.09-1.28% in experimental incubation, &lt;1% in hatchery incubation). A genome wide SNP analysis of a subset of progeny confirmed that they were double haploids. Cold-shock androgenesis was found to be effective in common carp, providing a new possibility of uniparental inheritance induction for isogenic line production.
