Abstract

We cytogenetically analyzed a triploid King-Nupchi strain of the olive flounder Paralichthys olivaceus to define the simplest, most rapid, and most effective method of ploidy analysis in aquaculture farms. Female triploidy of the flounder King-Nupchi strain was induced by cold shock (3 min post-fertilization at 2-4℃ for 45 min). Triploid induction was confirmed by erythrocyte measurement (nuclear volume, 29.15±2.10 μm3); flow cytometry (2.14±0.03 pg/cell); chromosome count (3N=72); Ag-NOR banding; and silver staining. Silver staining of finned cells obtained using a solid tissue technique was the most effective method of ploidy verification.
