摘要

Studies (1996-99) on the community structure of zooplankton in Coringa estuarine mangrove environment on the east coast of India revealed altogether 12 Biologically Important Species (HIS) of zooplankton represented by 6 major groups. Description of zooplankton structure included species composition, density and spatial distribution patterns of BIS at 15 GPS fixed locations. Acartia erythraea, bivalve veligers, Eucalanus elongatus, Paracalanus parvus, zoea of Scylla serrata, gastropod veligers and Acartia clausi were the important BIS species. The distribution and density of BIS revealed that the majority of them are represented by typical brackish water forms. The ambient salinity and degree of stability achieved through neritic influence are prime influencing factors in limiting the BIS distribution in the estuarine mangrove environment of Coringa.

由1996至1999年期間在印度東岸Coringa河口紅樹林濕地進行浮游動物群聚結構的研究結果，共發現12個重要物種(BIS)分別屬於6個主要類群。其中較常見的重要物種包括屬於橈足類之Acartia erythraea, Eucalanus elaongates, Paracalanus parvus,及Acartia clausi，二枚貝面盤幼體(bivalve veligers)，梭子蟹幼生(zoea of Scylla serrata)及腹足類面盤幼體(gastropod veligers)等。浮游動物群聚結構分析則是針對這些重要物種在15個衛星定位測站之組成、密度及分布情形進行描述，結果顯示大部分均屬於典型的半淡鹹水域種類。Coringa河口紅樹林水域之鹽度及穩定程度，受控於沿岸海水之入侵狀況，是影響及限制這些重要物種分布之重要因素。
