| Research Abstract |
This study attempts to clarify the role of thraustochytrids as a food source for zooplankton in the marine food webs. Feeding experiments were conducted to determine whether or not marine zooplankton could feed upon thraustochytrids. Both marine ciliate and rotifer could feed on thraustochytrids. Fatty acid analysis revealed that the rotifer fed upon thraustochytrids had polyunsaturated fatty acids (PUFA), particularly docosahexaenoic acid (DHA). The results strongly suggested that thraustochytrids play an important role as PUFA sources to marine zooplankton, especially DHA.
