The samples were collected during the research cruise on board the Norwegian research ship “Dr. Fridtjof Nansen” in February - March on the Congo River and Luanda monitoring lines. Zooplankton sampling was performed using a multinet net in an oblique trawl (2014) and a WP2 net in a vertical trawl (2015 and 2016), both with 180 µm mesh. The samples were fixed in 4% formaldehyde and analyzed in the oceanography laboratory of the National Institute of Fisheries and Maritime Research in Angola. In the three years of sampling, copepods were present in the zooplankton community. The diversity of copepods on the northern Angolan coast, from 2014 to 2016 in the hot season, included 27 genera corresponding to 19 families. The Copepoda class was the most abundant group in the zooplankton community, corresponding to more than 80% of the abundance, having been represented by the orders Calanoida, Cyclopoida and Harpacticoida.</abstract><trans-abstract xml:lang="ru">Обсуждается разнообразие и численность копепод в сообществе зоопланктона у северного побережья Анголы в жаркий сезон 2014-2016 гг. Образцы зоопланктона были собраны во время рейсов на борту норвежского исследовательского судна Dr. Fridtjof Nansen в феврале - марте на линиях мониторинга Луанды и реки Конго. Пробы зоопланктона отбирали с использованием мультисетевой системы - наклонный трал (2014) и сети WP2 - вертикальный трал (2015, 2016), обе с размером ячеи 180 мкм. Образцы закрепляли в 4%-м формальдегиде и анализировали в океанографической лаборатории Национального института рыбного хозяйства и морских исследований (INIPM) в Анголе. Копеподы присутствовали в сообществе зоопланктона все три года исследований. Веслоногие ракообразные у северного побережья Анголы в жаркий сезон 2014-2016 гг. были представлены 27 родами, относящимися к 19 семействам. Класс Copepoda оказался самой многочисленной группой зоопланктона, составляя более 80 % общей численности сообщества, и представлен тремя отрядами: Calanoida, Cyclopoida и Harpacticoida.</trans-abstract><kwd-group xml:lang="en"><kwd>zooplankton</kwd><kwd>north coast</kwd><kwd>Angola</kwd><kwd>copepods</kwd><kwd>zooplankton abundance</kwd><kwd>diversity</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>зоопланктон</kwd><kwd>северное побережье</kwd><kwd>Ангола</kwd><kwd>копеподы</kwd><kwd>численность зоопланктона</kwd><kwd>разнообразие</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Ré P.
