Abstract: This present study aimed to evaluate the using of micro-pore diffuser hose to provide proper aeration on hybrid catfish. The diffusers used in this study are two type, stone and micro-pore diffuser hose. The micro-pore hose were made of rubber that compressed and formed like pipe. Micro-pore that used in this experiment made by three shapes, linear (L), circular (Cr), parallel (P), and for control (C) using stone diffuser. Each of them was fitted to the bottom of tank and supplied air by blower with same pressure (90 mbar), all the experiments were carried out in triplicates. Sampling for water quality and growth were collected every 14 days for 60 days fish were reared. The performance of the hybrid catfish was measured by Specific growth rate (SGR), Growth rate (GR), feed intake (FI), survival rate (SR) and Harvest (H). The highest mean SGR was recorded in linear shape (1.58±0.30%), while the lowest recorded in control (1.42±0.24%). Growth rate showed that linear shape gain higher value than other (1.81±0.37 gr/days), while the control showed lowest GR (1.63±0.14 gr/days). The highest feed intake (5772.54±35.27 gr), and the lowest were (2764.30±84.61 gr). Survival rate shows identical result between linear and parallel shape (97.22±4.81%), while the lowest is control (33.33±8.33%), Harvest for linear shape gain highest (6512±59.12 gr) and the control recorded lowest value of harvest (2028±166.83%). Water quality parameter showed that treatment relatively better than control. All the experimented diffuser shows good result for growth hybrid catfish. However, linear shape performed best result among the other.
