ABSTRACT :

Cyclopoida are represented in the Indian Ocean by neritic and oceanic species. They have overwhelming abundance and play the diverse and important roles in marine food webs. Do we have enough knowledge on their species composition, spatial distribution, multiscale dynamics, and roles of different species in functioning of the Indian Ocean pelagic ecosystem? Today there are 94-95 identified species of 7 families: 1. Oithonidae (Oithona ¿ 21-22; Dioithona ¿ 4; Triconia ¿ 2); 2. Corycaeidae (Corycaeus ¿ 28; Farranula ¿ 7); 3. Lubbockiidae (Lubbockia ¿ 1; Homeognathia ¿ 1); 4. Oncaeidae (Oncaea ¿ 5; Archioncaea ¿ 1); 5. Sapphirinidae (Copilia ¿ 7; Sapphirina ¿ 14; Vettoria ¿ 1); 6. Clausidiidae (Saphirella ¿ 1); 7. Thaumatopsyllidae (Orientopsyllus ¿ 1). Among them there are cosmopolitan and endemic species, which constitute a most part. There is an apparent paucity of information on Cyclopoida. We conclude that identified species are not more than 60-70% of total Cyclopoida species in the Indian Ocean, that¿s we cannot discuss long-term changes of species composition in the ocean. A paucity of information on spatial distribution, temporal population fluctuations, ecology, migrations, and ecosystem roles of Cyclopoida is more pronounced. Some Cyclopoid species may swarm; we need to spend more attention to this aspect of their ecology to better understand pelagic ecosystem functioning. Available in literature data in different languages, including in Russian, on ecology Cyclopoida was not collected, summarized and analyzed enough yet. We must do this. We also need to initiate comprehensive studies on the taxonomy, distribution, population dynamics, biology and ecology of Cyclopoida in the Indian Ocean.
