Swamp water has a low pH value ranging from 3-4, this causes swamp water not yet be used optimally for fish culture. The optimum pH value for culture media of pangasius catfish (Pangasius sp.) is 6.5-8.5. One effort that can be done to increase the pH of swamp water by liming. This study aimed to determine the best dosage of cockle shell lime to increase water pH, growth and survival of pangasi…
