Night, surface zooplankton samples at one position in the West Passage of Narragansett Bay yielded 10 calanoid, three cyclopoid, and one harpacticoid species of free-swimming copepod nauplii. The seasonal abundance of all species of nauplii combined during the 12 months of study showed significant peaks in spring and mid summer. The holoplankters were grouped into four seasonal categories: summer–fall, winter–spring, spring, and year-round; the meroplankters were put in another category. The first two groups dominated the collections. The seasonal occurrence and relative abundance of the individual species of nauplii is shown for the period of study. Included is a short synopsis of the geographical distribution of the adults along the east coast of North America as recorded in the literature. |
