Abstract
Magnetically treated water has been used in many research, medical, industrial, agricultural and other fields. Therefore, the present study was conducted to study the effects of magnetically treated water with different intensities such as 500, 1000 and 1500 Guass in some aspects of life of the Iraqi freshwater snail, which is an important component of the food chain, Physa acuta (Drapanoud, 1805), and the results were compared to those living in the river (non-magnetically treated). The samples were collected from the Al-Khawaja channel in the Alexandria-Babylon region using the deep scoop. The current study showed a significant increases in the growth of the body of the animals under study. The size of the shells increased significantly with the height of the shell, the length of the opening of the shell, the width of the shell opening and the shell width by increasing the magnetic intensity, especially the density of 1500 Gauss compared to those living in the control water. The study also showed a significant increase in the values of the index of growth rates of shellfish for each of the snails treated with three treatments and non-treated snails from the first week of life to the last week. There was also a gradual increase in both the values of the treated water weight of the treated snails and the three intensities with control snails from the first week of the hatch and the last day of the life.
