| 中文摘要: |
| 对壳长为65 mm的皱纹盘鲍进行投喂2 d、饥饿1~4 d的周期性断食处理，连续投喂组作为对照。皱纹盘鲍的摄食、生长、排粪和血细胞组成的研究结果表明，当投喂2 d，饥饿天数少于2 d时，皱纹盘鲍的生长没有显著差异（P＞0.05），饥饿天数多于3 d，鲍体重开始下降；摄食率呈随解饿时间增加呈升高趋势，但实验组间无显著差异（P＞0.05）；排粪率与粪便中的有机物含量随饥饿时间增长而降低，其中，各处理阶段间的差异显著（P＜0.05）。血细胞中颗粒细胞的比例在饥饿少于2 d的实验组间无差异，但显著高于投喂2 d、饥饿3 d的实验组与投喂2 d、饥饿4 d的实验组（P＜0.05）。 |
| 英文摘要: |
| Aquaculture of abalone was limited in northern China by the lack of fresh food in summer. For a new feeding method, the Pacific abalone Haliotis discus hannai Ino at shell length of 65mm were treated with periodic starvation, i.e. feeding for 2d, then starving for 1~4d, with continuous feeding treatment as control. Results of growth, feeding, defecation and granulocyte suggested that there was no significant difference in growth when starvation was less than 2d (P＞0.05), while body weight dropped in other groups(more than 3d starvation). Food intake rate increased as starvation lasted, but there was no significant difference between each group (P＞0.05). Fecal production rate and organic matter in feces decreased with prolonged starvation, and it was significantly different during each treatment stage (P＜0.05); Ratio of granulocyte showed no difference in treatments of starvation less than 2d, and significantly higher for group of starvation less than 2d than groups of f2s3 and f2s4 (P＜0.05). |
