Abstract—

The oceans are changing on a global scale. Zooplankton of the marine ecosystem are microscopic myriads of diverse, floating and drifting animal-like organisms found either on or near the surface of water bodies. Zooplankton samples were collected from the surface water and substratum of the ship hull during the study period from June 2015 to May 2016. Population density ranged from 68 000 to 194 000 cells/L was recorded in the water and substratum of the ship hull. Shannon–Wiener’s diversity index (H') values ranged from 4.97 to 5.57 (bits/ind) at station I and station II. Simpson’s richness ranged from 0.967 and 0.977 at station I and station II. Pielou’s evenness index (J') ranged from 0.976 to 0.994 at station I and station II, respectively. In total, 56 and 48 zooplankton species were recorded in water and substratum of the ship hull in the Chinnamuttom harbor water, respectively. Among the recorded zooplankton, calanoid copepod was found to be dominant followed by ciliata, cyclopoida, harpacticoida, polychaeta, amphipoda and barnacle nauplii in water samples, whereas in substratum samples the Harpacticoid copepod was predominant followed by ciliata, cyclopoida, calanoida, polychaeta, amphipoda and barnacle nauplii. Among the estimated zooplankton, the copepods were found to be dominant throughout the year in the selected site and seasons with appreciable numbers.

印度东南海岸钦纳穆托姆渔港浮游动物的生态

摘要——海洋正在全球范围内发生变化。海洋生态系统中的浮游动物是在水体表面或附近发现的无数种多样、漂浮和漂移的动物状生物。在2015年6月至2016年5月的研究期间，从船体的地表水和底层采集了浮游动物样本。人口密度为68 000至194 000个细胞/L记录在船体的水中和底层中。在站点I和站点II，Shannon–Wiener的分集指数（H'）值范围为4.97至5.57（bits/ind）。在第一站和第二站，Simpson的丰富度介于0.967和0.977之间。Pielou的均匀度指数（J'）在I站和II站分别为0.976至0.994。Chinnamuttom港水域的水中和船体底层共记录到56种和48种浮游动物。在有记录的浮游动物中，在水样中，浮游桡足类占主导地位，其次是纤毛虫、类水蚤、叉足类、多毛类、两足类和藤壶无节幼体，而在底层样品中，软体桡足类居主导地位，然后是纤毛虫，类水蚤，浮游动物，多毛类，两足类，藤壶无节幼体。在估计的浮游动物中，桡足类在选定的地点和季节全年都占主导地位，数量可观。
