Impact of Nickel Intoxication on Ovarian Histology in Oreochromis mossambicus
The effect of chronic sublethal concentration of nickel on ovarian histology in two-month old Oreochromis mossambicus was analyzed histologically. The control ovaries showed abundance of vitellogenic oocytes with smooth and intact membranes and few atretic and previtellogenic oocytes. The ovaries of...
