ABSTRACT
The present study was conducted to determine the effects of magnetized water treatment with in different intensities 500, 1000 and 1500 Gauss on some ecological aspects one' species of freshwater Ostracoda Cyclocypria kinkaidia Dobbin 1941, which important species in faun of aquatic habitats of Iraq. This species are considered a component of the food chain.The obtained results compared with these species which lived in the river [control]. These samples of Ostracodean animals were collected from Al - Habebia lake in Baghdad province by using the test sieve with mashed sized about 75um and zooplankton net with opening diameter about 25 cm and mesh sized 335 um.These species were exposed to three different intensities 500,1000 and 1500 Gauss magnetized water treatment under laboratory conditions, the resulting effects were compared with those obtained from a control experiment where the individuals kept in normal untreated water.Result of these experiments showed the indicated variation in the some physical and chemical characteristics of water.The present study showed non significant change in pH values, electrical conductivity and total dissolved solids in the magnetized water. But increased these values was increased with increased intensity of magnetized water treated with 1500 Gauss intensity for Ostracodean animals where restrict this study.Dissolved oxygen concentration was signifi cantly increased intensity of magnetized water especially in treated water with 1500 Gauss intensity for Ostracodean animals comparated with untreated water. Nonsignificantly change in water temperature values with increased intensity of magnetized water comparrison with untreated water where those Ostracodean animals lived
ABSTRACT
Magnetic energy controls on a Sot of cosmic phenomena, as well known that the magnetic properties are not confined to iron and manganese, but a feature associated with all solids, liquid and gas, as well as all life.This research was conducted to identify the effect of magnetic water treatment in various intensity [500, 1000 and 1500] gauss in some aspects of life for the Iraqi fresh water ostracoda Cyclocypris cruciata Furtos 1935, which is an important component of the food chain in the waters.The samples of Ostracoda were collected from Al-Habebsa lake in Baghdad governerat by using sieve with mesh sized 75 micro m and zooplankton net with opening diameter about 25 cm and mesh size 335 micro m.Results were compared between the control animals that live in the natural waters with those treated with three different magnetic intensities. Research has shown a significant increase in the growth rate of the length and width of the shield for each male and female of the ostracoda with the increases in the intensity of magnetic water treatment, especially in 1500 Gauss.As well as, get a significant increase in the fertility of animals with the increases of magnetic intensity, also increase in the number of eggs and diameters per female treated compared with control.While sex ration didnet shows any differences between the control and water treated animals
