研究了不同温度对内刺盘管虫Hydroides ezoensis幼虫生长发育及变态的影响.结果表明:24 ℃下内刺盘管虫的孵化率最高(85.20%±2.36%),30 ℃下孵化率仅为1.70%±1.70%,按孵化率大小依次为24 ℃>21 ℃>18 ℃>27 ℃>30 ℃;30 ℃下孵化时畸形率、死亡率大幅增加,18～27 ℃下孵化正常,且27 ℃下孵化时间最短(511 min);5种温度下内刺盘管虫幼虫圆盘直径大小随时间变化呈"弧"形分布,体长则逐渐上升;18 ℃下幼虫在试验第12 天全部死亡,而在21、24、27、30 ℃下浮游期存活率分别为75.73%±4.55%、74.03%±5.98%、64.43%±4.20%、58.67%±8.54%;变态率以24 ℃下最高(60.45%±7.52%).

The effects of different temperatures (18, 21, 24, 27, and 30 ℃) on growth, development and metamorphism of Hydroides ezoensis larvae were studied in the present experiment. The optimum temperature for incubation of H.ezoensis was found at 24 ℃ with the hatching rate of 85.20%±2.36%. The minimal hatching rate of only 1.70%±1.70% was observed at 30 ℃ with the rang as 24 ℃>21 ℃>18 ℃>27 ℃>30 ℃. There was significant increase in the malformation and mortality in group 30 ℃ compared to other groups. The larvae were hatched normally from 18 ℃ to 27 ℃, the shortest incubation period of 511 minutes at 27 ℃. The larvae had a large diameter at first and then had small diameter as they developed and growth. For group under 18 ℃, all larvae died at the 12th day. Survival rates of the pelagic larvae was found to be 75.73%±4.55%, 74.03%±5.98%, 64.43%±4.20%, and 58.67%±8.54% for the groups 21, 24, 27 ℃, and 30 ℃, respectively, with the optimum metamorphic temperature of 24 ℃ (metamorphic rate of 60.45%±7.52%).
