1991年和1992年，在亚北极太平洋西部的浅海和海洋区域进行了浮游植物自然种群的孵化。在孵育过程中，观察到Parmales目、绿藻纲中的藻类数量增加。在5 ~ 12 °C光照条件下，裸甲藻的生长速率为0.012 ~ 0.016 h-1或0.41 ~ 0.54 d-1，低于硅藻，但与一般甲藻相当。异养领鞭毛虫在光照和黑暗条件下的生长速率分别为0.016 ~ 0.040 h-1和0.54 ~ 1.39 doughd-1，与15 °C时的生长速率相当或略低。结果表明，Parmales可以在光照下生长，并喜欢低温。
Incubations of natural populations of phytoplankton were carried out in neritic and oceanic areas of the western subarctic Pacific in 1991 and 1992. Algae in the order Parmales, class Chrysophyceae, were observed to increase in number during the incubations. In the light-exposed treatments, the growth rate of Parmales at 5 to 12 °C was 0.012 to 0.016 h-1or 0.41 to 0.54 doubling d-1, which is lower than that of diatoms, but comparable to that of common dinoflagellates. On the other hand, heterotrophic choanoflagellates grew positively in both light and dark at the rate of 0.016 to 0.040 h-1or 0.54 to 1.39 doublings d-1, which is comparable or lower than the reported value at 15 °C. The results obtained demonstrate that the Parmales can grow vegetatively in light and prefer low temperatures.
