Abstract
This study aims to determine the growth of Striped Catfish fingerlings (Pangasianodon hypophthalmus) and using Fine Bubbles (FBs) application with various pressures in the aquaponic system. The study was conducted at the Laboratory of Aquaculture, Ciparanje, Faculty of Fisheries and Marine Sciences, Padjadjaran University from 18th September to 18th October 2019. The method used in this study was the experimental method using Completely Randomized Design (CRD) with four treatments and three replicates. Treatment A: Control (without FBs), Treatment B: FBs with pressure 4.5 atm, Treatment C: FBs with pressure 5 atm, and Treatment D: FBs with pressure 5.5 atm. This research used water spinach as biofilter. The measured parameters in this study were fish growth, plant productivity, and water quality which includes levels of temperature, dissolved oxygen, nitrate, ammonia and phosphate. The results showed that the highest fish specific growth rate in treatment D is 6.68 ± 0.43%/day with a survival rate of 100 ± 0.00%, the highest plant productivity, with a stem length of 115.03 cm, a weight of 62.75 g, and leaf growth of 30 strands. While the water quality parameters including temperature, dissolved oxygen concentrations ranged from 24.2-27°C, 7.72-7.94 mg / l, nitrate 0.243-0.602 mg /, ammonia 0.001-0.010 mg / l and phosphate 0.147-0.229 mg / l respectively.
Keywords: Fine Bubbles, aquaponic, striped catfish, growth rate, water quality.
