| 中文摘要: |
| 在室内可控环境下对褐菖鲉进行了不同饥饿时间处理，通过分析饥饿对褐菖鲉消化道指数及肌肉成分的变化情况，研究了饥饿对褐菖鲉消化道指数及肌肉成分的影响。褐菖鲉在饥饿胁迫下，随着饥饿时间的延长，其肠道萎缩，比肠长逐渐变小，与对照组相比，差异显著(P<0.05)；比肝重、比胃重、比幽门重指标均随着饥饿时间的延长而下降，其中比肝重下降幅度最大,饥饿21d的比肝重与对照组相比下降了85.033%；饥饿对褐菖鲉肌肉中水分、蛋白质、脂肪和灰分含量变化有显著影响，蛋白质、脂肪含量皆显著下降（P<0.05）,水分含量显著增加（P<0.05）,而灰分含量变化不大，差异并不显著(P<0.05)。 |
| 英文摘要: |
| Experiments were conducted to study the effects of starvation (0, 3, 7, 14, and 21d) on the ratios of liver weight to body weight, stomach weight to body weight, pylorus weight to body weight, and intestine length to body length, and muscle composition in Sebastiscus marmoratus reared in culture water under indoor conditions. We observed that all of the digestive organs atrophied and all the ratios decreased during the starvation period. The ratio of intestine length to body length decreased gradually and showed a significant difference compared to the control group (P<0.05). The ratio of liver weight to body weight decreased most dramatically (P<0.01), showing a decrease of 85.033% at 21d compared to the control group. At the meantime, starvation resulted in the increase of water and ash contents, and the decrease of the protein and fat contents. |
