Description
Summary:A breeding experiment on Pangasius sutchi was conducted from July 2008 to September 2008 in a hatchery in West Bengal, India, using three different inducing agents, each injected at two different dosages: carp pituitary extract (CPE) and two synthetic hormones, Ovaprim and Ovatide. The fertilization rate was 82% to 91%. Hatching took place within 34 to 36 hours from the time of fertilization, with a hatching rate 73% to 79%. The response to spawning with CPE was best with Ovatide and Ovaprim in terms of percentage of fertilization, high hatching rate, and ease of stripping.
