The Effect of using Fine Bubbles (FBS) on the Growth of Catfish Seeds (Pangasianodon hypopthalmus) with Different Stocking Density on Aquaponic System Using Fine Bubble

This study aims to determine the stocking density that can increase the survival rate of catfish seeds and to analyze the growth rate of catfish seeds in aquaponics systems using FBs. The catfish seeds used in this study were 4-5 cm in size with a weight of 0.5-1.0 g. The types of plants used were ground water spinach from the seedlings themselves and the FBs used had a pressure of 5.5 atm. The method used was an experimental method with a completely randomized design consisting of treatment A 375 fish, treatment B 450 fish, treatment C 525 fish, and treatment D 600 fish with a volume of water of each treatment is 150 L. Catfish seeds were maintained for 35 days. The results of statistical tests showed no significant difference and SR was also not significantly different. Statistically, the aquaponics system using FBs was able to support stocking densities of up to 600 individuals/150 L.
