Abstract

In April, July, October 2012, and January, April 2013, marine nematode dominant genera and feeding types were sampled for diversity analysis from five mangrove wetlands（Zhangjiang Estuary in Yunxiao Country, Jiulongjiang Estuary in Longhai City, Fenglin in Xiamen City, Luoyangjiang Estuary in Quanzhou City, Wanwu in Ningde City）in Fujian Province. It was found that the nematode dominant genera with dominance of percentages≥5% were Sabatieria, Ptycholaimellus, Parasphaerolaimus, Terschellingia, Daptonema, Viscosia and Dichromadora, which had dominance by 19.82%, 7.88%, 7.45%, 7.26%, 6.79 %, 6.00%, 5.25%, respectively. Sabatieria was the most predominant genus in the mangroves wetlands of Zhangjiang Estuary, Jiulongjiang Estuary and Luoyangjiang Estuary, with dominances are 27.87%, 28.37%, and 23.40%, respectively. Terschellingia was the most dominant genus in Fenglin mangrove wetlands, with a dominance of 18.10%. Daptonema was the most dominant genus in Wanwu mangrove wetlands, and dominance was 22.86%. The seasonal variations in abundance of their feeding types were as follows, in Zhangjiang Estuary wetlands, 1B>2A>2B>1A. In Jiulongjiang Estuary wetlands, 1B>2B>2A>1A. In Fenglin wetlands, 1B>2A>2B>1A. In Luoyangjiang Estuary wetlands, 2B>1B>2A>1A. In Wanwu wetlands, 2A>1B>2B>1A. Therefore, type 1B marine nematode showed to be the dominant in Zhangjiang Estuary, Jiulongjiang Estuary and Fenglin, type 2A was dominant in Wanwu wetlands, type 2B was dominant in Luoyangjiang Estuary wetlands, type 1A are the lowest in five regions.
