Popis:	A reliable method for gynogenetic mass-production has been developed in carp (Cyprinus carpio L.). The effect of different cold shock treatments applied after fertilization were examined. The yield of viable diploid gynogenetic animals could be significantly increased when the cold shock was applied 5 min or 15 min after fertilization. A negative correlation has been found between the effectiveness of these two treatments, so both were used on separate batches of eggs. By means of gynogenesis, the crossover frequency and map distance of the transferrin locus have been determined. Successful pilot experiments were made on grass carp (Ctenopharyngodon idella Val.) and sheatfish (Silurus glanis L.) with respect to gynogenetic mass production.
