The results show that 154 species were found in the area,including 60 species of Polychaeta,30 of Crustacea,28 of Mollusca and 24 of Echinodermata;the dominant species are not very distinct,the relative important or common species are Listriolobus sp.,Xenophthalmus pinnotheroides White and Cossurella dimorpha Hartman.

本次调查共获得长江口附近海域大型底栖动物154种，其中多毛类环节动物60种，甲壳动物30种，软体动物28种，棘皮动物25种，其它类群动物11种。群落中优势种的地位都不明显，只有螠虫(Listriolobus sp。)、豆形短眼蟹(Xenophthalmus pinnotheroides White)、拟单指虫为相对重要的种类。

The results show that the number of zoobenthos species declines in rice-duck farming ecosystems compared with conventional paddy.

结果表明：与常规稻田相比，稻鸭共作使水体底栖动物的种类数减少。

In order to study the impact of rice-duck farming ecosystem on zoobenthos biodiversity in paddy waters, surface soil samples taken from rice-duck farming ecosystem and conventional paddy fields were analyzed for zoobenthos biodiversity.

在水稻不同生育时期对稻鸭共作稻田和常规稻田的土壤取样，研究不同稻田生态系统水体底栖动物的生物多样性。

The total number of zoobenthos in rice-duck farming ecosystem declines remarkably during the early stage of rice growth, but almost equals that of conventional paddy at late growth stage.

水稻生育前期，稻鸭共作使底栖动物的个体总数减少较大，后期与常规稻田差异较小。

Among the water insect distribution, the most found species was zooplankton, and the dragonfly and damselfly were the next. There were 16 families and 22 geniuses of insects found in Ba-Lein and Lau-Mai rivers.

根据现场勘查，八连与老梅溪中之水栖昆虫中以蜉蝣为最多，其次为蜻蜓、豆娘、水黾、石蝇、等共16科22属，生物多样性指数介於1.4~3.5之间，并且有由下游至上游渐增的趋势。
