Abstract:

Abstract: The effect of starvation periods and refeeding on blood physiological and non-specific immune parameters in Carassius auratus gibelio(15.6 ±0.84) were studied. Compared to the control, the content of blood glucose and malondialdehyde (MDA) were significantly decreased during starvation (P <0.01 ). The starvation led an initial significantly decreased superoxide dismutase (SOD) activity followed by increased. The phosphatase (ACP) activity was not effected in short-term starvation, however prolong the starvation, ACP activity increased, but then sharp declined (P<0.01). The content of blood glucose and MDA, the activity of SOD and ACP were significantly increased in short-term starvation group after re-feeding. The content of blood glucose and Hb , ACP activity also increased, however, SOD activity and content of MDA were significantly declined in middle-term starvation（P<0.05）after re-feeding. The content of blood glucose and MDA were remarkable declined compared to control, but ACP activity was gradually restored to the control level in long-term starvation after re-feeding. The results showed that short-term hunger and then re-feeding could enhance metabolism and non-specific immune function of Carassius auratus gibelio .
