Abstract

The euphausiids (Class Crustacea: Order Euphausiacea) one of the major components of the marine zooplankton occurring in the EEZ of the west coast of India (eastern Arabian Sea) and collected during the cruises of FORV Sugar Sampada during 1985-1992 period from the epipelagic zone were subjected to specieswise study for their distribution in space and time and for their ecology and biology. Seventeen species were encountered of which Pseudeuphasia latifrons (at an average density of 258/lOOOm^ of water), Euphausiia diomedeae (1,256), E. sibogae (1,437), Nematoscelis gracilis (309), Stylocheiron armatum (230) and S. qffine (216) were the most abundant and cosmopolitan in occurrence. The other 17 species namely Thysanopoda monacantha, T. tricuspidata, T. astylata, E. tenera, E. pseudogibba, Nematobrachion flexipes, S. suhmii, S. microphthalma, S. longicorne, S. abbreviatum and S. maximum were rather sparsely distributed and their average number per lOOOm^ of water ranged between 10 and 151 only. The major species exhibited marked variations in population during different months and seasons mainly depending on the changes in the environment.
