| 摘要: |
| 采用实验生态学方法，通过分析摄食喜好系数、平均个体摄食量等参数，研究香螺（Neptunea arthritica cumingii）摄食选择性，以及温度、饵料状态对香螺摄食量的影响。结果表明，香螺成螺对不同的饵料具有明显的摄食选择性，喜食程度的顺序依次为缢蛏（Sinonovacula constricta）、菲律宾蛤仔（Ruditapes philippinarum）和毛蚶（Scapharca subcrenata）。随着温度的升高，不同规格香螺摄食量先升高后降低，摄食高峰出现在15℃，香螺对于已开壳饵料的摄食量显著高于未开壳饵料。 |

| Abstract: |
| This study aimed to demonstrate feeding preferences and effects of temperature and bait state on the food intake of Neptunea arthritica cumingii using the feeding preferences coefficient, average individual food intake, and other parameters. The results indicated that N. cumingii was a remarkable species that was selective toward diverse baits, with a clear preference for Sinonovacula constricta, Ruditapes philippinarum, and Scapharca subcrenata. With increasing temperature, the food intake of N. arthritica cumingii having different sizes first incereased and then decreased. The feeding peak was observed at approximately 15℃. The food intake of N. arthritica cumingii was significantly higher than that of the unopened bait. |
