Abstract

The results of meiobenthic survey on Con Dao Archipelago (Vietnam) is present. Samples were collected in five locations in mangroves and on the adjacent reef-flat. Quantitative date form meiobenthos is given along with taxonomic composition of two most abundant groups^ nematodes and harpacticoids. High species diversity occurs in two main groups – harpacticoid copepods and free-living nematodes. High level of species diversity together with a large number of singleton species prevents direct comparison on the species level and makes it non-informative. The general characters (composition of families and the spectra of live-forms) are more informative. The taxonomic composition of each of the studied bays were shown, inter-biotopic differences make a smaller contribution to the overall diversity, i. e. each bay has its own set of species, from which the population of each of the biotopes is formed with no respect to the distance.
