中文摘要：对银鲫 (Carassiusauratusgibelio)进行投喂、饥饿 (1～ 4周 )、饥饿投喂 (饥饿 2周再投喂 2周 )处理后 ,测定其血液组分和卵巢发育的指标。结果表明 :饥饿处理后银鲫血液中血糖、甘油三酯的含量显著降低 ;红细胞数量、血红蛋白含量和胆固醇含量先显著降低 ,随后回升到投喂组水平 ;在饥饿过程中白细胞的数量、红细胞的长短径、红细胞沉降率和总蛋白均无明显变化。饥饿投喂处理的银鲫血液中红细胞数量、甘油三酯和胆固醇含量与投喂组无差异 ,但血糖含量仍显著低于投喂组 ,而白细胞数和血红蛋白含量显著高于投喂组。饥饿 4周延缓了银鲫卵巢发育 ,其性腺成熟系数和卵径均显著低于投喂组 ;饥饿投喂组的性腺成熟系数和卵径仍显著低于投喂组。分析说明饥饿阻碍了银鲫的卵巢发育 ,而饥饿对银鲫血液组分的影响在再投喂后得到恢复。

外文摘要：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:①The 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.②Starvation 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.
