Abstract

In 2012-2013, mangrove sediment samples were collected from four stations in Jiulong River Estuary in Longhai City and Luoyang River Estuary in Quanzhou City. The individual dry weight of marine nematodes was analyzed in four seasons. Based on size measurements of the dominant nematode genera, the individual dry weight ranged from 0.14 to 4.88 μg for adults, from 0.17 to 1.87 μg for juveniles, with an average of 0.826 μg per individual. The analysis showed that the proportion of the juvenile nematodes in different seasons and the species composition were the main factors affecting the estimation of the individual biomass of marine nematodes. For better estimation of nematode biomass, it is suggested to calculate by direct measurement, while simple estimation by using 0.8 μg/ind. is practical for the estimation of nematode biomass in mangrove sediments.
