Abstract
This research was carried out in the research fish farm – Faculty of agriculture – Mansoura University during season 2011 in order to study the effect of controlling the water temperature and the quantity of pumping air on tilapia fish growing dissolved oxygen quantity and power consumption in fish farm to reach the study goal the tilapia fish were cultured in two cement ponds (experimental and the traditional pond). The cement experimental pond was built as a cuboid-shaped with dimensions of 1500 ´ 1000 ´ 1800 mm length, width and height respectively. The pond has been equipped with Adding air compressing unit provided with perforated pipe, heating unit and water supply source. On the other hand the traditional pond with cylindrical shape has diameter of 1500 mm and height of 800 mm. Air was added with a hose in the traditional pond at the center of the pond bottom. The aeration system was evaluated in the two ponds by measuring the dissolved oxygen concentration, determine the uniformity of the dissolved oxygen, calculate the air quantity and measure the fish growing rate. From the prior results it can be concluded that the fish pond aerator using the perforated pipe is suitable for the tilapia fish at perforated pipe depth of 1200 mm, distance between holes of 150 mm and air pressure of 0.2 bar which obtain the suitable dissolved oxygen uniformity (the difference between the maximum and the minimum dissolved oxygen value) of 1.5 mgl-1, with average of 6.92 mgl-1, the highest growth rate in the experimental pond was higher than the traditional system about 60.74 % and keep the dissolved oxygen higher than the low limit to fish good life about 1.92 mgl-1. This experimental pond conditions with the perforated pipe may give a chance to more perfect diffusion for fish along the all pond size.
