“…The high salinity was observed during summer (April-June) might be due to low rainfall and high degree of evaporation of surface water. Similar observations were recorded in the earlier report [2,20].…”

“…In all the stations the lowest temperature was recorded between October and December and highest in the month of April, May and June. The similar type of water temperature ranges was reported in earlier observations [2,19,20] in Gulf of Mannar and Palk Bay region.…”

“…Zooplankton acting a vital role in the aquatic realm due to the direct influence on phytoplankton and play in higher trophic levels also [1]. Fishery productivity can be indirectly influenced by zooplankton in marine sector [2]. Marine zooplankton comprises of a broad range of different organisms with about ten thousand species of meroplankton which includes small flagellates to large jellyfish.…”

“…Copepods are the major group of zooplankton in terms of biomass, abundance and species number in marine pelagic ecosystems [3]. They are the most important secondary producers in coastal and marine ecosystems which holds link with phytoplankton and higher tropic level animals [2]. They are extensively distributed throughout the world and represents about 80% of the total zooplankton biomass in marine environment [4].…”

“…Copepods are one of the most broadly studied marine zooplankton groups especially on the species composition, temporal distribution in the Indian coastal waters [6,7,8,9,10,11]. There are about 210 described families, 2,280 genera and more than 14,000 species of copepods were recorded throughout the world [2]. As per the earlier reports, about 540 copepod species were documented in Indian waters [13].…”

The aim of this study was to find the species abundance and composition of copepod zooplankton in four selected sites such as Karangadur, Thevipattinam, Athangarai and Mandapam in Palk Bay region during February 2022 to January 2023. There is no significant difference (P<0.05) in water temperature, salinity, DO and pH values between the sites during this study period. In this study, we have observed 46 species of copepods belongs to 30 genus, 20 families and four orders. The overall percentage of copepod species composition in the four collection sites was: Calanoida (58.7%), Poecilostomatoida (17.4%), Harpacticoida (15.2%) and Cyclopoida (8.7%). In Athangarai site, a maximum of 40 copepod species were recorded. In Karangadu site, 34 species, in Devipattinam site, 28 species and in Mandapam site only 25 species were observed. In calanoid copepods, Acartia, Calanopia and Temora was the dominant genus which representing three species. In Poecilostomatoida order, four families, seven genus and eight species were observed. Out of the seven genus, Corycaeus was the dominant genus which comprises two species such as Corycaeus crassiusculus and C. speciosus. In Harpacticoida order, six families, six genus and seven species were recorded. Among the six genus, Longipedia represents two species (Longipedia coronata and L. weberi). The order Cyclopoida, has only one family, two genus and four species. Among the genus, Oithona was the dominant genus which contains three species. Among the 20 families, Pontellidae was the dominant one includes six species.
