تأثير استخدام الماء الممغنط على نمو أصبعيات أسماك الكارب الاعتيادي Cyprinus carpio

Abstract EN

The current study was conducted to determine the effect of water treated magnetically on fingerlings common carp fish.

The study included four different treatments: first treatment (control treatment) contained a normal water which non-treated magnetically, while the other three treatments have been magneted by three different intensities with (500, 1500, and 2500) Gausses (G) respectively.During this experiment, all of the growth effects (such as the increase in the average weight and the relative growth rate) as well as the phenotypic characters (such as the total length and body depth) in addition to the physical characters (average of the dissolved oxygen, PH and EC water) were measured and calculated in order to determine which treatment is the best in terms of increasing the physiologic dynamic growth of carp fingerlings.The study concluded that, treated water magnetically by 2500 G was provided a better environment for the fish growth by improving the physical characters (higher dissolved oxygen rate, best PH and less EC), which reflected positively on all the growth indicators (average weight gain and the relative growth rate) as well as to improve the phenotypic characters (such as total length and body depth).
