“…The comparison of zooplankton density between seagrass ecosystem and the control station revealed that the former is more than the later. Jeyaraj et al, (2016) observed the maximum density of 11733 nos./m 3 in the Gulf of Mannar region. The species richness value of zooplankton in all both the stations varied from 2.97 to 7.13.…”

“…The number of species is more in seagrass ecosystem compared to the other stations. Anandakumar and Tajuddin (2013), Pitchaikani and Lipton (2015), and Jeyaraj et al, (2016) have documented 72, 49 and 114 species of zooplankton respectively in Gulf of Mannar region. Among the zooplankton species, diatoms were found to be the dominant group followed by meroplanktonic forms.…”

“…Catch composition of minor groups recorded in shore seine fishery 1999). So far, 114 species of zooplankton have been reported from GoM, in which copepods were dominant (Jeyaraj et al, 2016) and 43 species of diatoms and 2 species of blue-green algae recorded from PB. The food content of oil sardines collected from the shore seines were mostly copepods and the species Microsetella rosea was dominant in the diet.…”

The southeast coast of India bordering Gulf of Mannar and Palk Bay has luxuriant growth of seagrass beds which sustain good fisheries and is a biodiversity hotspot. Many fishers living along the coast depend on these resources for their livelihood. Several species of invertebrates and vertebrates fully depend on the seagrass resources for their survival and sustenance. In this paper, the diversity of species commonly associated with the seagrass beds and their present status is presented followed by the fisheries associated with this ecosystem. The type of fishing activities including the details of crafts, gears, number of fishers involved and catch statistics are presented. The main objective of this approach is to understand how the fishing activities influence the ecosystem and fishermen. Underwater monitoring and visual observations were documented through photographs and videos. Artisanal fishing activities such as bottom set gillnet, push net, lead-fish trap net and shore seine are in detail discussed and the conservation measures which are urgently required are also presented.

Zooplankton play a pivotal role in connecting primary producers and high trophic levels, and changes in their temporal and spatial distribution may affect the entire marine ecosystem. The spatial and seasonal taxonomic composition patterns of mesozooplankton in Bohai Bay were investigated in relation to a number of water parameters. Bohai Bay is a eutrophic semi-enclosed bay with dynamic physico-chemical conditions influenced by terrestrial inputs and seawater intrusion. The results showed that under the condition of terrigenous input, the diversity of mesozooplankton species near the eutrophic Haihe River Estuary and Jiyun River Estuary was lower than that in the central Bohai Bay, with gelatinous Oikopleura dioica as the dominant species. The mesozooplankton diversity was highest in the bay mouth affected by seawater intrusion, and the dominant oceanic species, mainly copepods Corycaeus affinis, Calanus sinicus, and Oithona similis, entered the inner bay from the bay mouth. Meanwhile, the abundance of mesozooplankton in summer was significantly higher than that in autumn. Compared with historical data, the dominant species in Bohai Bay has evolved from arrow worm Sagitta crassa to copepod Paracalanus parvus, probably due to global warming, indicating the effects of human activities on the succession of mesozooplankton community.
