| Abstract | ||
| effect of some environmental factors on the density of the adult of the barnacles Balanusamphitriteamphitrite was studied at water intake of Al-Najibiyah electric power station for the period from December 2010 until November 2011, as samples were collected a record of 12 duplicate each month of the study area as well as measured the environmental factors. Results showed that the density of adult barnacles ranged between (55-139) individual / 100 cm 2 water temperature ranged between 16.4 ºc - 28.5 ºc and salinity between 1.2 - 2 mg / L, pH between 6.8 to 7.8, the concentration of calcium ranged between 310-470 mg / L, dissolved oxygen between 2.8 - 4.2 mg / L and the vital requirement of oxygen ranged between 1.3 - 9.4 mg / L. As shown a positive relationship between adult density and salinity, pH and the concentration of calcium and dissolved oxygen in water, while an inverse relationship emerged between adult density and water temperature and the vital requirement for oxygen. | ||
