Distribution of planktonic ostracods along the south-west coast of India

Abstract

Fourteen species of ostracods were identified from the collections of 2 cruises of Blue Fin (February and April 1970) off the south-west of India. Euconchoecia aculeata and Cypridina dentata were the most common and abundant species which showed aggregation above the thermocline. For certain species, viz. Microconchoecia curta, Orthoconchoecia atlantica and Spinoecia porrecta discontinuity layer did not act as a barrier in their vertical movements. Some species like Conchoecetta giesbrechti and Metaconchoecia rotundata showed aggregation below the thermocline.
