Dominant species were comprised of mainly micro- and meso-zooplankton species and planktonic larvae of benthos such as Parvocalanus crassirostris, Cirripedia nauplius, Oithona attenuata, Acrocalanus gibber, Nauplius, Bivalvia veliger, Copepodite, Oithona simplex and so on.

Biological Activated Carbon Filter could provide ideal habitats for invertebrates, but invertebrates may lead to aesthetic problems and adverse health effects of drinking water. This paper studied the invertebrates in biological activated carbon filters in a water plant of the south of China during Sep. 2006 to Sep. 2007. The results implied that BAC filters were colonized by invertebrates, in which 23 species of invertebrates were found, the dominating organism group was the rotifer, and others included Copepoda, Cladocera, Oligochaeta, Nauplii and Nematoda.

生物活性炭(Biological activated carbon， BAC)滤池能够为无脊椎动物提供理想的生境，但无脊椎动物可能给饮用水带来负面的健康效果和感观问题。2006年9月～2007年9月，对南方某水厂BAC滤池无脊椎动物滋生状况进行了为期13个月的调查研究，共发现无脊椎动物23种，优势类群为轮虫，其他类群还有桡足类、枝角类、寡毛类、无节幼体、线虫等。
