Achuthankutty,-C.T.; Nair,-S.R.S.; Haridas,-P.; Madhupratap,- M. Zooplankton composition of the Kalpeni and Agatti Atolls, Lakshadweep Archipelago. INDIAN-J.-MAR.-SCI. 1989. vol. 18, no. 3, pp. 151-154. Composition of zooplankton in the lagoons was quite different from that of the sea and, to a large extent, was independent of oceanic influence. While copepods were dominant in the sea, meroplankton, particularly brachyuran zoeae constituted the largest group in the lagoons. Zooplankton standing stock was lower in the lagoons as compared to the sea. Among copepods, calanoids showed higher abundance in the sea whereas harpacticoids and cyclopods dominated the Kalpeni and Agatti lagoons respectively. Several striking similarities were observed in the zooplankton composition between the coral and coastal lagoons.
