    Abstract
    Chaetognaths from the Rodriguez Triple Junction and adjacent parts of the Indian Ocean were studied based on zooplankton samples collected during July to September 1993. Chaetognaths population drastically reduced to the RTJ area (av 158/1000 m sup(3)) as compared to the Central Indian Ocean (av 639/1000 m sup(3)). A total of 15 species of chaetognaths belonging to the genera Eukrohnia, Krohnitta, Sagitta and Pterosagitta were found in the collections. Contribution of epi, meso and bathypelagic species were respectively 60, 33 and 7 percent to the total population. Species diversity was more in the upper 500 m water column than the 150 m stratum due to the mixing of mesopelagic species in the former. Statistical grouping of stations indicated the presence of ecologically significant factor groups. Community structure of chaetognaths indicated predominance of Sagtta pacifica in the upper 150 m water column while in the 500 m S. hexaptera was the dominant species. At the RTJ area the predominance of S. hexaptera alongwith unusual congregations of P. draco area could be associated with the difference in temperature due to hydrothermal activity
