New findings of the flying fishes <italic>Cheilopogon furcatus</italic>, <italic>C. nigricans </italic>and <italic>Prognichthys occidentalis</italic>, halfbeaks <italic>Oxyporhamphus micropterus similis </italic>and <italic>Hemiramphus balao </italic>in the study area allow us to somewhat update current ideas about the distribution of these species. Our collections show a sharp dominance in numbers of four-winged flying fishes (subfamily Cypselurinae) over two-winged flying fish (subfamily Exocoetinae), which dominated the study area in previous years. In addition, within the subfamily Cypselurinae, the nerito–oceanic species <italic>Hirundichthys affinis</italic>, <italic>C. nigricans </italic>and <italic>P. occidentalis</italic>, which were previously absent or rare in the study area, began to quantitatively predominate over the oceanic species <italic>H. speculiger</italic>,<italic> C.</italic> <italic>exsiliens </italic>and<italic> P.</italic> <italic>glaphyrae. </italic>We attribute all these changes to invasion of large quantities of sargasso seaweeds (genus <italic>Sargassum</italic>) in the study area,<italic> </italic>which apparently facilitated colonization of open ocean waters by previously rare species. Large quantities of sargasso weeds may also lead in the future to the increasingly frequent appearance in the open waters of the tropical Atlantic of coastal species characteristic of flotsam, such as <italic>Lobotes surinamensis</italic>, <italic>Caranx crysos </italic>and <italic>H. balao.</italic></p></abstract><trans-abstract xml:lang="ru"><p>Приведены данные о поимках в открытых водах северной тропической части Центральной Атлантики 16 видов рыб из восьми семейств. Новые обнаружения летучих рыб <italic>Cheilopogon furcatus</italic>, <italic>C. nigricans</italic> и <italic>Prognichthys occidentalis</italic>, полурылов <italic>Oxyporhamphus micropterus similis</italic> и <italic>Hemiramphus balao</italic> в районе исследования позволяют несколько дополнить современные представления о распространении этих видов. В сборах отмечено резкое доминирование по численности четырёхкрылых летучих рыб (подсемейство Cypselurinae) над двукрылыми (подсемейство Exocoetinae), доминировавшими в районе исследования в прошлые годы. Кроме того, внутри подсемейства Cypselurinae нерито-океанические виды <italic>Hirundichthys affinis</italic>, <italic>C. nigricans</italic> и <italic>P. occidentalis</italic>, которые ранее отсутствовали или были редки в районе исследования, стали количественно преобладать над океаническими <italic>H. speculiger</italic>, <italic>C. exsiliens</italic> и <italic>P. glaphyrae</italic>. Все эти изменения мы связываем с появлением в районе исследования больших количеств саргассовых водорослей (род <italic>Sargassum</italic>), поспособствовавших, по всей видимости, освоению вод открытого океана ранее редко встречавшимися здесь видами. Большое количество саргассов может привести в будущем и к всё более частому появлению в открытых водах тропической Атлантики прибрежных видов, характерных для плавника, таких как <italic>Lobotes surinamensis</italic>, <italic>Caranx crysos</italic> и <italic>H. balao</italic>.</p></trans-abstract><kwd-group xml:lang="en"><kwd>flying fishes</kwd><kwd>Exocoetidae</kwd><kwd>Hemiramphidae</kwd><kwd>Lobotes surinamensis</kwd><kwd>Caranx cryos</kwd><kwd>Phtheirichthys lineatus</kwd><kwd>Sargassum</kwd><kwd>Central Atlantic</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>летучие рыбы</kwd><kwd>Exocoetidae</kwd><kwd>Hemiramphidae</kwd><kwd>Lobotes surinamensis</kwd><kwd>Caranx crysos</kwd><kwd>Phtheirichthys lineatus</kwd><kwd>Sargassum</kwd><kwd>Центральная Атлантика</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Министерство науки и высшего образования Российской Федерации</institution></institution-wrap><institution-wrap><institution xml:lang="en">Ministry of Science and Higher Education of the Russian Federation</institution></institution-wrap></funding-source></award-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Правительство РФ</institution></institution-wrap><institution-wrap><institution xml:lang="en">Government of the Russian Federation</institution></institution-wrap></funding-source><award-id>0149-2019-0009</award-id></award-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Правительство РФ</institution></institution-wrap><institution-wrap><institution xml:lang="en">Government of the Russian Federation</institution></institution-wrap></funding-source><award-id>0128-2019-0009</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Баширова Л.Д., Сивков В.В., Кулешова Л.А. и др. 2020.
