Invasion
Invasion Description
1st Records: St. Petersburg area/Russia/Neva Bay (2007, Alekseev et al. 2009, 59°32'36'' N, 29°28'17''); Russia/Luga Bay (2007, Alekseev et al. 2009, 59°24'13'' N, 28°11'6'' E),). These copepods were identified by molecular identification as matching the North American East Coast subclade that was also introduced to San Francisco Bay, Grays Harbor, and the Great Lakes (Lee 2000; Alekseev et al. 2009; Sukikh et al. 2013)

| In some years (2010, 2015), Eurytemora carolleeae was the dominant, replacing native E. affinis in Neva Bay, Gulf of Finland, Russia, but was less abundant in the nearby Luga Bay, with lower summer temperatures, and higher fish predation. Eurytemora carolleeae has higher fecundity and larger egg-sacs, giving it a competitive advantage, but increasing vunlerabilty to fish predation (Sukhikh et al. 2019). | ||
