Abstract

The present study was designed to investigate the effect of magnetic water technique and different stocking density on water quality parameters and growth performance of Nile tilapia (Oreochromis niloticus) and Common carp (Cyprinus carpio). Magnetic water at 14500 gausses (1.45 Tesla) was used compared with normal water (0 gauss) for experimental groups of fish which reared with three different levels of stocking density 12, 25, 50 fish/m3 and each group was replicated with an average initial weight 10 g/fish. Experimental fish were fed on commercial diet (25 % protein). The fish tanks were supplied with aeration and filtration systems. At the end of the experiment, the results indicated that water quality and growth performance improved significantly (P<0.05) in magnetic water treatment compared to the normal water with different stocking densities. The results recorded that dissolved oxygen, pH and total hardness values in magnetic water increased in comparison with the normal water, but ammonia was inversely related to magnetic field, while total alkalinity and water temperature were not affected by treatment. The data revealed that growth performance, water quality improved and significantly in magnetic water treatment between different stocking densities, and pointed that, the stocking density of 12 fish/m3 with magnetized water was the best treatment. Results indicated that fish reared in magnetic water treatment improved significantly (P<0.05) compared to those in the normal water with different stocking densities. In shortly, applying magnetic water on aquaculture definitely on Nile tilapia and Common carp farming improves growth performance.
