| 本文对烟台海域海月水母水母体阶段伞径、腕长及体重的生长规律进行了研究,并首次对其生长过程中水管系统的发育进行了观察。结果表明,在人工培养条件下,海月水母体重(W)与伞径(D:15~150㎜)呈幂函数增长；腕长(L)与伞径(D)呈线性关系；伞径生长曲线方程为：Dt = 4×10-6t4-0.0014t3 0.1087t2 0.5079t 9.428 (R2=0.9993)。。海月水母初生碟状体出现主辐管与间辐管,3日龄时碟状体出现从辐管,11日龄时出现环管、分离点。随着水母的生长,伞径增大,水管系统的分离点数与聚合点数逐渐增多,成熟时1/4伞部分离点数最多为66个,聚合点数最多为32个。 |
| 英文摘要: |
| The growth models of the diameter, wrist length and weight of the moon jellyfish medusa in Yantai waters were studied in this present study, and the development of radial canals was observed in details for the first time. Our results showed that the cultured moon jellyfish (15-150mm of the umbrella-part diameter) displayed a power function growth equation between weight and diameter, and a linear relationship between the wrist length and diameter. The growth curve equation of diameter of Aurelia aurita is Dt = 4×10-6t4- 0.0014t3 0.1087t2 0.5079t 9.428 (R2=0.9993). The perradial canals and interadial canals appeared in the newly released ephra. The adradial canals formed in the 3-day ephyra. And the Ring canal formed in the 11-day ephyra with the divergences. The number of convergences and divergences increases with the development of the moon jellyfish medusa diameters. Moreover, the maximum number of convergences and divergences in 1/4 umbrella of mature moon jellyfish medusa was 66 and 32, respectively. |
