Abstract A survey along the coast of India (~1100 km stretch) between Benaulim (Goa) in the west coast and Thoothukudi (Tamil Nadu) in the east coast was conducted during summer 2014, to evaluate the mesozooplankton community structure. Zooplankton community was dominated by holoplanktonic forms representing 93.7% of the total zooplankton, while meroplanktonic forms constituted 6.3%. Zooplankton was generally dominated by copepods which contributed about 69%. In total, forty-eight species of copepods belonging to eighteen families dominated the zooplankton abundance, with a significant contribution of small-sized copepod genera, viz. Bestiolina, Parvocalanus, Acrocalanus, Corycaeus, Oncaea and Oithona. Total mesozooplankton and copepod density ranged from 80 ind. m−3 to 804 ind. m−3 and 28 ind. m−3 to 570 ind. m−3, respectively. Considerably higher abundance of cladocerans (Penilia avirostris and Evadne tergestina) with a significant contribution to zooplankton biomass (r2 = 0.984, p

热带沿海水域中型浮游动物的空间异质性

摘要 2014 年夏季,在西海岸的 Benaulim(果阿)和东海岸的 Thoothukudi(泰米尔纳德邦)之间的印度海岸(约 1100 公里范围)进行了一项调查,以评估中型浮游动物群落结构。浮游动物群落以全浮游形式为主,占浮游动物总数的93.7%,而小型浮游形式占6.3%。浮游动物一般以桡足类为主,约占69%。总共有属于 18 个科的 48 种桡足类动物主导了浮游动物的丰度,小型桡足类属的贡献很大,即。Bestiolina、Parvocalanus、Acrocalanus、Corycaeus、Oncaea 和 Oithona。中型浮游动物和桡足类动物的总密度范围为 80 ind。m−3 至 804 工业。m-3 和 28 英寸 m−3 至 570 英寸 分别为 m−3。
