Abstract

The effects of genetic manipulation of eggs and sperm on the yields of gynogenetic fry of Puntius gonionotus were investigated. Gynogenesis was achieved by cold-and heat-shocking eggs fertilized with ultraviolet irradiated sperm of P. schwanenfeldii at various times after fertilization and at different duration intervals. 66.6% viable, gynogenetic fry were obtained when eggs were inseminated with irradiated sperm and cold shocked at 2°C for 5 minutes duration 1 minute after fertilization. At warm water temperature shocks the fertilized eggs performed best at 42°C, with percent survival rates of 20.0% 1 minute after fertilization for 1.0 minute duration and 17.2% and 14.7% 13 and 23 minutes after fertilization respectively for a duration of 1.5 minutes.
