Effects of Starvation on Blood Composition and Ovarian Development in Carassius auratus gibelio

Blood compositions and ovarian development in Carassius auratus gibelio were examined after treating by feeding (control group),4-week starvation,and 2-week starvation followed by 2-week refeeding,respectively.Results were as following:1)The red blood cell count,hemoglobin,blood glucose,triglycride and cholesterol contents were decreased significantly.The white blood cell counts,the size of red blood cell and the total serum protein contents were similar to the level of control group during starvation period.After being refed for 2 weeks the blood glucose content of the starvation-treated fish was still significantly lower than the control group.2)Starvation delayed the ovarian development,and decreased the gonadal somatic index and egg diameters.After being refed for 2 weeks the ovarian development of the starvation-treated fish was still lagged behind that of control group,and gonadal somatic index and egg diameter were lower than that of control group.Analysis showed that the blood composition of starvation-treated fish could recover to the level of control fish after refeeding,and starvation delayed the ovarian development.
