| 摘要: |
| 中华鲎(Tachypleus tridentatus)是保障我国医疗检测安全的重要战略生物资源,国内外中华鲎行为生态学相关研究极少。在实验室内模拟砾石底(NS)、细砂(SS)、中砂(MS)、粗砂(CS)、泥(AR)、泥沙1 (AA)、泥沙2 (AB)和沙泥(SA) 8种不同比例的泥沙类型对中华鲎行为特征的影响。结果表明,稚鲎较多时间潜藏于泥沙中,较少时间裸露于泥沙表面活动(如爬行、游泳等)。稚鲎偏好在含淤泥较多的泥沙类型中潜沙,且在泥质和泥沙质类型中埋栖时间较在沙质中埋栖时间长;在裸露于泥沙表面时,稚鲎相对偏好栖息于沙质底。泥沙环境下稚鲎用于游泳的时间比例高于砾石底。在凌晨、上午、中午、下午、夜晚5个时间段中,稚鲎在夜晚和凌晨活动较活跃。通过揭示不同比例的泥沙类型底质对中华鲎稚鲎行为特征的影响,为野外增殖放流计划的设计与实施、放流适宜地点的选择以及稚鲎人工养殖环境的优化提供科学理论依据。 |

| Abstract: |
| Horseshoe crab Tachypleus tridentatus is an important strategic biological resource for ensuring the security of Chinese medical detection.Eight substrates in different grain sizes of pebble,sand,silt,and mud or their mixture were used for the substrates in an aquarium tank in laboratory,on which the impact of different substrates on the behavioral preference of T.tridentatus was simulated.Observation showed that juvenile horseshoe crabs hid into substrates most of the time and went out of substrates temporarily for crawling,swimming,etc.Juvenile T.tridentatus preferred to muddy substrates for hiding,spent more time on swimming in the substrate-paved environment than in bare gravel bottom,and inclined to inhabit in sandy substrates.Among 5 diurnal periods of a day (before dawn,forenoon,noon,afternoon,and night),they were more active before dawn and at night.Therefore,the effects of different substrates on the behavioral characteristics of T.tridentatus are different.This study provided a scientific basis for the design and preparation for the culture or proliferation projects of the species,for the selection of suitable releasing sites,and for the optimal artificial breeding environment building for juvenile horseshoe crabs growth. |
