Abstract

This research was conducted in Reproduction Pond of Faculty of Fishery and Marine Science of University of Riau Pekanbaru, from December 2012 until January 2013. This study was performed to know the effect of feeding fish by diets containing vitamin C in form of ascorbic acid on growth and survival rate of catfish (Ompok hypoptalmus).
